Partition vs. Volume. If you have a partition with Monterey (for example) and you create a second partition and install Sonoma (for example) and after using it you decide to keep Sonoma and get rid of Monterey you can't because you are not allowed to delete the first partion so you can't really get rid of the Monterey installation. If you make a second volume in the Monterey partition and install Sonoma and it works and you like it you can just delete the Monterey volume and you're done. Also, you can just drag all your apps from the Monterey Apps folder into the Sonoma apps folder and you're good to go. Possibly there may new variations in the file system but I imagine the utility that comes inside Disk Utility can clean that up if you run it. In any case, I have done this process on many Macs for each new OS that comes out without an issue. My 2009 MBP went from Catalina to Big Sur to Ventura to Monterey to Sonoma. Each time I was amazed at how well it ran on the new OS but I always had a fall back volume. Now, all the clutter is gone and I just have a Sonoma volume on the 2009 - Amazing. OCLP is definitely Amazing!
Thank you Mr. Macintosh for yet again a very easy to follow OCLP install tutorial. I truly appreciate you dedication to the whole Mac community and save our unsupported Macs from the recycle bin. Best CO2 avoiding action for any computer is to give it a long and happy running life extension. Kudos.
Mid 2010 MBP running Monterey SUCCESS! (with SSD and 6Gb RAM). Zoom and Maps not working as expected. Chose Monterey to avoid USB1 issue. Surprisingly usable for light duty work with little memory pressure despite only 6Gb RAM. Strangely Activity Monitor shows no GPU activity despite dock transparency clearly present. Your excellent videos are indespensable! Thanks for all your hard work Mr. Macintosh!!
WORKED FLAWLESSLY! I was referred to your vids from a thread on Reddit. I was having trouble following the official documentation and your video helped a lot. I upgraded my 2014 Mini to 14.1.2, then a few minutes later got a notification that OCLP 1.3.0 was available for 14.2, so upgraded OCLP and then OSX. I next wanted to test Sonoma on my 2011 Mini since I currently have it running HomeBridge for my smart devices, Plex, and it does a bunch of other stuff. I saw this vid to walk through creating an external drive (or a dual boot) for OSX. Again, worked flawlessly. OCLP doesn't show support for 14.2 on a 2011 (yet) so I added 14.1.2 to a 2 TB external SSD. Now need to get the other services on it and will swap out the SSD and install the 16 GB RAM. Not bad for a dual core i5 powered machine designed more than a decade ago.
You will remain the best. I do not know how to thank you. I felt that the Mac mid-2012 that i had become new in everything. a difference there is between the old system that I was working on and what is now, that everything is available in speed and aesthetics.

Great video, Mr. Macintosh! One tip for your viewers interested in multiboot is to configure OCLP to always show the boot picker via Settings in the OCLP app, which allows one to bypass the need to hold Option key at boot to get the OpenCore boot picker. I use multiboot on my vintage Macs to select among different installations: (1) I always keep a version of the last natively supported version of macOS just in case; (2) one or more versions of macOS installed via OCLP, typically Ventura which works well on my vintage Macs, and Sonoma which I’m testing and is problematic on some of my older Macs; (3) my favorite Linux distro, right now Linux Mint 21.2.
Hey there, I'm hoping you can help. I run macOS Monterey (latest supported), Windows 10 (bootcamp partition), and Fedora, all natively in a multi boot configuration on my mid 2015 MBP. I want to run Ventura or Sonoma. I created the OCLP installer, but it attached to the Windows boot loader, not macOS like I expected. I can still boot into any of the 3 OSs, but I can't complete the installation of the unsupported macOS. I'm trying to figure out how to get OCLP to attach to the macOS boot loader.
My 2 Cents. Install the last supported OS on the main drive, THEN add a volume and install opencore and the new OS. If you ever have severe problems, you can always Otn+Cmd+R+P, then hold down option at startup and boot to the last supported system. The 6-10 GB of "wasted space" is worth the sanity check.
At the moment i have setup a triple boot with Opencore: Ventura running on my MacMini (2014) and on an external disk Win11 and Linux MX (on two different partitions). I installed Win11 on the external hd using WinToUSB and the MacMini drivers downloaded through the Bootcamp app. Everything works perfectly and i am able to boot to any of the 3 OSes by pressing Option at boot.
I have to say that this is what I did with both my OCLP installations. Both were on >2012 iMacs, so the idea of opening the case and swapping out the internal drive for an SSD was too much of a hassle. So I just plugged the SSD into one of the USB 3.0 ports and they both run every bit as fast as if they were internal drives. Also, I had no issues installing OCLP.
@@sjn7220 Not really, but then I don't reboot very often lol. Actually my larger iMac 2012 does take a bit of time, but that's simply because it's got to time when looking for signs of life from the very dead internal drive. When it's thoroughly convinced that the internal drive is not going to respond it then defaults to the SSD. But again, it doesn't bother me because I only do it once in a blue moon. If you're talking about the process of loading the UI and all that after logging in though, I can say that I've never had any problems along those lines.
@@denniseldridge2936 Thanks. I seemingly need to reboot more often than normal due to the computer crashing for reasons I can't figure out. I turned on verbose booting but it hasn't been helpful in figuring out the boot delay.
Just about to do this on my wife's machine. Any recommendations for which external SSD to purchase? What's the best connection to use on the late 2012 iMac? Does it have thunderbolt or usb type c? Which is the fastest transfer speed? (Sorry I'm tech savvy but I use Windows rather than OSX so not too sure on some Mac things)
@@danludlam1562 So here's the state of my journey through OCLP. The external SSDs I've used have been name brand SATA SSDs attached to generic USB 3.0 adapters. This used to work great with older versions of OCLP, but the latest versions seem to fail when I try to install even versions of macOS that worked perfectly originally. But I've pretty much given up as I really didn't see much advantage in using macOS for my purposes. But it was a great learning tool, as I'm a tech by trade and I really did need to get to know the whole Mac thing more deeply. I'm back to Windows now where all the tools I use for fun and profit all just work. I'd love to have a new M-series Mac though hehe.
Attempted this using the guidance on the OCLP site; greviously mistaking it for a better and simpler guide; many hours later I have an option to install Sonoma but am afraid and can find little info. as to what that means i.e. install where and with what implications for the current OS. Three or so hours spent trying to format a USB drive to APFS but the iMac is apparently convinced that it is its mother and won't allow any alteration. In short I would have been wiser to follow this advice here.
great video, I have an old iMac mid 2011 and thinking of trying to use the external hard drive using big slur or monterrey on my old mac, but not sure though.
Great video! I had OCLP set up on a MacBook Pro 15' 2017 and I went to update it to version 1.2.1...after rebooting I was only getting to the login screen where I would enter my password and no loading bar would appear and it would just hang. Tried to boot into EFI recovery but that also produced a hanging black screen. Was directed by a different video of Mr. Macintosh's to keep an OCLP USB handy (which I did not have handy), so I made a bootable Sonoma drive for 14.2.1 with the OCLP GUI application on another Macbook. I did not build and install Opencore on the USB, only installed macOS. Plugged the USB into the problem Mac Pro and booted holding 'Option' key to get to boot options, then pressed 'Control' key while clicking on 'EFI Boot.' Was brought to an additional boot options Menu where I could select the 'Install MacOS' option from my USB. If you select 'Install MacOS' option on the first menu on boot instead of 'EFI Boot' you may be greeted with a startup error apple logo and link, so make sure EFI Boot first, then USB installer. Waited anxiously through a series of reboots and progress bar pages and sure enough was able to boot to a login screen, enter my password, and get back into my Mac Pro without losing any data. Thanks a bunch!!!!!
So far this works great. Can't figure out how to update to the latest version of Ventura, since I originally installed it. I am on 13.6.7 and want to install 13.6.8.? Thanks for your great tutorials.
I was hoping that updating the supported OS while the OCLP OS was on the same drive would get a mention; I've done two; the first seemed to work fine but the second one has brought up an alert from Apple along the lines of: Volume hash error - reinstall OS; so it seems that OCLP on the EFI interferes with OTA updates of the supported OS. An extensive search indicates that the install of both types of OS on the same drive as depicted in this video may have been the only case ever recorded in either video or print - on the Internet.
You do such a great job. But I think there is a small problem. It could be Mac's upgrade 14.1 or Open Core. 1.2, but Ram has been affected. I realized my 2015 MacBook Pro is eight years old, but with the problem of loading on the upgrade of Mac 14 things are not the same. Buffering has or could be a big problem without Clean My Mac. I also realize that buffering can be a problem of too many open tabs or programs running in the background. I have deleted and turned off everything but what is needed to make it open up and run. Nothing helps, the crux of the problem is with Yellow Mail it will not open up just the small circle that keeps turning. Thanks for listing. Carl
This was the video I was waiting for. You are the best! I have a 2014 macbook pro and a 2014 27” iMac. Both stuck on Big Sur. Been very undecided on what to do. I was thinking about trying this first. Not sure about Monterey or Ventura or even Sonoma. Do you have any recommendations?
I got Monterey installed on an external USB 3 ssd on my 2012 imac and it works fine BUT reboots are super slow (almost 10 min). Had to revert back to Catalina and reboots are a minute or 2. Wish I could figure this out.
Many thanks for this wonderful tutorial. Worked perfectly. I did an upgrade but my logic pro x now doesn't boot up. Is there a patch or solution for this? Also my final cut pro is requesting I buy a new license . Is there a patch or work around to fix these urgent issues?
Many thanks for this great tutorial. I did an upgrade and it worked perfectly. However, my LOGIC PRO X is no longer working and my FINAL CUT PRO is requesting a new license. Is there a patch or solution around these? I need to sort them out urgently. Thanks
just spent 4 hours trying to install this onto a usb drive, just keeps re-booting doing same install over again, waste of time really, just glad it hasnt ruined my mac pro
Thank you so much for all the content, much appreciated! I currently have a 2013 iMac with the 1TB fusion drive. Rather than taking it apart to upgrade the HD i have been using a crucial external SSD as my boot drive. Works awesome, but I'm stuck with Catalina. Does anyone know if OCLP installed with Sonoma or Ventura on the external SSD would work? and would i just leave the internal fusion drive as is? thanks in advance.
I’m so glad I DONT really need to watch these videos you make anymore. In the nicest way lol. Upgraded all my stuff to 2023/2024 systems. So I can take a few years off open core 🎉🎉. Still love ur videos man
Installing to an external USB drive: Now that I've installed to the USB drive, how do I delete the "Install" partition (or expand the Macintosh HD External) partition? It is taking up 25% of my external drive. How do I recover that space?
Please, looking for assistance. The instructions worked perfectly for me and I have the new OS on my external hard drive. Rather than moving on to the 2nd volume option I want to keep the new OS on my external drive for a few days. However whether I first shut down or restart and hold the option key I'm no longer able to access the new OS on my external. In summary what I'm trying to do is to be able to switch between my regular OS on my hard drive and the new OS on my external. I appreciate any assistance on how to do this, sincere thanks!
I would like to use the same USB across all types of Macs - Can you install the OCLP as to use for any Macs or do you have to specify the build beforehand? I followed everything, but wanted to use this same setup from a MacBook Air 2013 to a MacBook Pro 2013.
When I watch this video, the currently available OCLP version is 1.2.1 and macOS version is Sonoma 14.1.1. But my successful experiences vary in Sonoma 14.0, 14.1 and 14.1.1 on internal and external SSD start up drives. The worst case so far has been the MacBookPro13,2 (Late 2012) where the internal SSD can use Sonoma 14.0 and external SSD fails to start up Sonoma 14.1.1 and not even able to do Recovery 14.1.1 (dmg) after EFI 14.1.1. (same versions of KDK applied and Ethernet cable / usb-c adapter connected)
great work allways view your posts ... question i have got sonoma on main drive on mac mini i7 2012 i also have monterey on usb drive works treat if i put in mac internally will it still boot up like it does on usb or is usb boot install os only gonna work via usb keep the expert knowledge flowing
**Excellent video** Is it possible to repeat this process and install 2 additional macos on 2 additional partitions, from 2 additional thumb drives? TIA
I loved you video and your patience and positive attitude and genuine passion for the subject matter, but I am sorry to say I spent 10 hours over and over with your video and I cannot get os Monterey installed on my MP3,, 1. I cannot get passed this infinite loop to keep reinstalling Monterey over and over again. it just refuses to cooperate or even to toss me a freaking bone
Thanks a lot for this video, very useful ! I have one question. Is it possible to keep one Volume with Monterey and one volume with Sonoma on the same disk (with a Mac Pro 2013) ? Thanks for your advice.
heh. Couple of months ago I removed my main SSD with OCLP Ventura from my mbp late 2011. I replaced it with a brand new SSD and installed linux mint on it. After couple of months on linux mint, I thought it would be nice to have a dual boot. I bought an optibay and put Ventura SSD onto it. Then I realized it won't be that easy to just boot into Ventura. Besides, it turned out, linux makes it somewhat tricky to access APFS volumes. I'm wondering, is this tutorial suitable for such cases as mine, or it is just for installing from scratch?
I had to boot from external for my every day use because my 2018 Mac mini only came with 256gb and I can’t increase it. Having kernel panic issues after using open core for the past 12 months. But it had been fine off the usb c
Thank you for this video Mr Mackintosh, I tried this to load Ventura on a MacMini 2014 + Magic keyboard and mouse, Main OS is Ventura OCLP 1.2, could get to 1st Reboot and screen displayed both internal drives but keyboard/mouse not connected - is this just a case of resetting NVRAM and PRAM per issue 251? or do I need to buy a wired mac keyboard? Alternatively should I install Monterey on the USB disk first?
Thanks for this very helpful tutorial. I’ve been running Monterey on a Mac Pro 5,1 using both ssd and a Samsung nvme, using clover configurator. I wanted to update and transfer to open core patcher so installed Ventura on another ssd using oc from my mbp pro 2015. All worked great, rebooted fine through the mbp. I then placed the drive in my Mac Pro but it wouldn’t boot. Can you or do you know why that may be? Thanks
Failed for my iMac (Retina 5K, 27'', ultimo 2014, FusionDrive). Following all the steps, but never get an option to select my external SSD. Everything runs fine up to 14:18 Min. SSD is formatted Mac OS Extended (journaled). Think there is a problem with the OCLP Bootloader (1.4.3) under Big Sur.
Hi, Mr. Macintosh. Right at the end of the instructions you emphasize that the dual boot will work with a native macOS as the 1st partition - just as we saw it in your video. But while watching I was asking myself if this kind of Dual Boot also works, if the 1st partition already has installed an unsupported macOS? To be exact: I have a MBP 2011 running (unsupported) 10.15 Catalina. Is it possible to install a 2nd unsupported macOS on this internal SSD? Thank you in advance.
@Mr.Macintosh Need your help/ideas Whenever I have two macOS versions installed on my unsupported MacBook Pro with OCLP, I always have the problem that iCloud displays a issue when I switch from one system to the other and I have to log in to iCloud again each time. This happens every time I switch from one macOS version to another. I currently have macOS 14.7 installed on the internal SSD and macOS 15.0 installed on the external SSD (Samsung T7) the day before yesterday. I need the same Apple-ID on both macOS. 👉🏻 Is there a solution to this?
Successfully running Ventura on my old late 2013 iMac on an external SSD. However, my Zoom TAC-8 Thunderbolt device is not working. System Report shows it under "Thunderbolt/USB4" and as "connected". Just booted into Catalina, and it's working fine there, and the System Report seems to show the same info (TAC-8 as connected). I've re-installed all the TAC-8 drivers, but nothing worked. I could try a clean install of Ventura, but wondering if anybody is using Thunderbolt?

Do you follow the same steps if you have a 2012 Mac mini with two internal hard drives? I would like to leave the original fusion HDD alone, and install OCLP/MacOS Sonoma on my recently purchased SSD. Now when you add the 1.3.0 OCLP update into the mix, it just leaves me confused. Please help Mr. McIntosh for I do not know where to begin!

The Big Sur begins to load and then half way stops. Any help would be appreciated, please and thank you.
I don't know what I'm doing wrong, but booting from external drive fails for me on Mac Mini 2012 (macmini6,2). Tried from SD card, from an external SSD, issue is the same. It's a shame because the machine is still great, but the internal hard drive is as slow as it gets. Is there anything one can do to force boot from external drive? I even tried Carbon Copy Cloner after installing successfully to the internal drive, to copy the entire contents of the internal to the external drive (external drive still shows up and bootable since I tried installing the OS there). But it doesn't get pass the boot screen.
Thanks for the tutorial. This is my first OCLP install, I did Big Sur on a mid-2010 MBP, and it seems to have gone perfectly. 1 Question Please: After I option-click EFI Boot, I'm seeing extra USB drives with crazy names like "___~ks ujV_" and "_______p0_D@l". Are these an issue? If so, how do I kill them? Thanks
My OCLP-Intaller gets to 307 mb and then stops. i tried a 128gb flash drive and a 240gb ssd. both stopped in the same area it sted thaat i dont have permission to save file.
Thank you! I have a question: I have a 2015 MBP with OS X 10.11 El Capitan, but I’d like to test Monterey (officially supported on my Mac, so no need to use OCLP) on an external SSD, but I’m afraid that the boot selector tool won’t detect the SSD after the installation, since El Capitan cannot read APFS volumes. Is this possible or do I need to upgrade to High Sierra before?

Mr.Macintosh, it is very important for me to uprade my Macbook Pro Retina 15" mid 2012 to Ventura.Currently running Mojave. Using external drive backed up with SuperDuper I am trying to use my backup done by SuperDuper but boot software cannot do it since the backup is not in APFS format. Is the upgrade a good option. If the compatibility list says Macbook Pro does it mean it include my Retina model. Would really appreciate your help in this matter.
ive done this exactly the same more than 10 times, from updating to clean install and when i reboot, i never get the efi pop up to say that sonomo is available to install. it always greys out the install. ive looked online, ive asked people. ive got nothing in return.
i've manage to install ventura on my old hp desktop pc by downloading a copy of olarila ventura from their website along with one of their haswell efi folders everything works well except for wifi and sound i haven't figured it out yet i wanted to try patching a few things up so i decided to install oclp everything went fine according to your video but after finishing up i don't have the option to boot into oclp boot menu i guess because i'm using an unsupported pc that's only designed to run windows is it anyway possible to get oclp boot-menu from my hp "thanks"
Nicely explained! Big question: I run Monterey on my Mid11 iMac. It works mostly and to be safe for the business I have to stick to it. But I miss certain things, as not all works well or even at all on Monterey. It seems it should be possible to create a dual boot with High Sierra as the secondary system. But: Do I have to erase all and start with High Sierra first and add Monterey, or can I keep Monterey an add High Sierra. How to format the High Sierra partition? Will it work on APFS - then I could only add a volume, correct? - or do I have to make it macOS Extended (journaled)?
@@LernGuru Ok, Thanks Lern!.Its the best one, ive been studying this.. can you post the results please.... Black magic speed test.if you have 2015 or newer it will be faster.Mr macintosh is very busy guy..lol
@@stephencawker1565 I wanted to partition from inside of Monterey but got an information that it may take forever and it should be significantly faster to partition from the recovery in the installer. This however did not work. So, I went back to Monterey, bit in the bitter apple - pardon the pun - and created a partition for High Sierra with the format You suggested. Presently, High Sierra is installing on its partition. I will let You know, when it's done.

Partition vs. Volume. If you have a partition with Monterey (for example) and you create a second partition and install Sonoma (for example) and after using it you decide to keep Sonoma and get rid of Monterey you can't because you are not allowed to delete the first partion so you can't really get rid of the Monterey installation. If you make a second volume in the Monterey partition and install Sonoma and it works and you like it you can just delete the Monterey volume and you're done. Also, you can just drag all your apps from the Monterey Apps folder into the Sonoma apps folder and you're good to go. Possibly there may new variations in the file system but I imagine the utility that comes inside Disk Utility can clean that up if you run it. In any case, I have done this process on many Macs for each new OS that comes out without an issue. My 2009 MBP went from Catalina to Big Sur to Ventura to Monterey to Sonoma. Each time I was amazed at how well it ran on the new OS but I always had a fall back volume. Now, all the clutter is gone and I just have a Sonoma volume on the 2009 - Amazing.

I can still boot into any of the 3 OSs, but I can't complete the installation of the unsupported macOS. I'm trying to figure out how to get OCLP to attach to the macOS boot loader.
Great tutorial, thx.
For those with issues getting the installer to run through without errors - boot to safe mode before running OCLP, worked for me

Do you have slow reboots? I did this as well to a 2012 iMac but it takes forever to reboot compared to Catalina. Had to go back to Catalina.
@@sjn7220 Not really, but then I don't reboot very often lol. Actually my larger iMac 2012 does take a bit of time, but that's simply because it's got to time when looking for signs of life from the very dead internal drive. When it's thoroughly convinced that the internal drive is not going to respond it then defaults to the SSD. But again, it doesn't bother me because I only do it once in a blue moon. If you're talking about the process of loading the UI and all that after logging in though, I can say that I've never had any problems along those lines.
@@denniseldridge2936 Thanks. I seemingly need to reboot more often than normal due to the computer crashing for reasons I can't figure out. I turned on verbose booting but it hasn't been helpful in figuring out the boot delay.
Just about to do this on my wife's machine. Any recommendations for which external SSD to purchase? What's the best connection to use on the late 2012 iMac? Does it have thunderbolt or usb type c? Which is the fastest transfer speed? (Sorry I'm tech savvy but I use Windows rather than OSX so not too sure on some Mac things)
@@danludlam1562 So here's the state of my journey through OCLP. The external SSDs I've used have been name brand SATA SSDs attached to generic USB 3.0 adapters.
This used to work great with older versions of OCLP, but the latest versions seem to fail when I try to install even versions of macOS that worked perfectly originally. But I've pretty much given up as I really didn't see much advantage in using macOS for my purposes. But it was a great learning tool, as I'm a tech by trade and I really did need to get to know the whole Mac thing more deeply. I'm back to Windows now where all the tools I use for fun and profit all just work.
I'd love to have a new M-series Mac though hehe.
THANK YOU! This worked as was trying to figure out how to boot new Sequoia OS from external SSD on my 2013 iMac.
Attempted this using the guidance on the OCLP site; greviously mistaking it for a better and simpler guide; many hours later I have an option to install Sonoma but am afraid and can find little info. as to what that means i.e. install where and with what implications for the current OS. Three or so hours spent trying to format a USB drive to APFS but the iMac is apparently convinced that it is its mother and won't allow any alteration. In short I would have been wiser to follow this advice here.
Thank you for your wonderful and educational efforts at the same time
Thank you for your work making these videos.
great video, I have an old iMac mid 2011 and thinking of trying to use the external hard drive using big slur or monterrey on my old mac, but not sure though.
I’ve been using oclp. With Ventura and Sonoma on external drive. No problems
As always an top tier video
thank you very much for this walkthrough! It answered all my questions!!!!
Great video! I had OCLP set up on a MacBook Pro 15' 2017 and I went to update it to version 1.2.1...after rebooting I was only getting to the login screen where I would enter my password and no loading bar would appear and it would just hang. Tried to boot into EFI recovery but that also produced a hanging black screen. Was directed by a different video of Mr. Macintosh's to keep an OCLP USB handy (which I did not have handy), so I made a bootable Sonoma drive for 14.2.1 with the OCLP GUI application on another Macbook. I did not build and install Opencore on the USB, only installed macOS.
Plugged the USB into the problem Mac Pro and booted holding 'Option' key to get to boot options, then pressed 'Control' key while clicking on 'EFI Boot.' Was brought to an additional boot options Menu where I could select the 'Install MacOS' option from my USB. If you select 'Install MacOS' option on the first menu on boot instead of 'EFI Boot' you may be greeted with a startup error apple logo and link, so make sure EFI Boot first, then USB installer.
Waited anxiously through a series of reboots and progress bar pages and sure enough was able to boot to a login screen, enter my password, and get back into my Mac Pro without losing any data. Thanks a bunch!!!!!
You are so Good at what you Do!....Thanks...
So far this works great. Can't figure out how to update to the latest version of Ventura, since I originally installed it. I am on 13.6.7 and want to install 13.6.8.? Thanks for your great tutorials.
Thank you for your videos ! It's a great help for using OCLP.
This video helped me out a lot - Thanks!
I was hoping that updating the supported OS while the OCLP OS was on the same drive would get a mention; I've done two; the first seemed to work fine but the second one has brought up an alert from Apple along the lines of: Volume hash error - reinstall OS; so it seems that OCLP on the EFI interferes with OTA updates of the supported OS. An extensive search indicates that the install of both types of OS on the same drive as depicted in this video may have been the only case ever recorded in either video or print - on the Internet.
VIELEN VIELEN DANK HERR MACINTOSH !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
Thank you, perfect tutorial!
You do such a great job. But I think there is a small problem. It could be Mac's upgrade 14.1 or Open Core. 1.2, but Ram has been affected. I realized my 2015 MacBook Pro is eight years old, but with the problem of loading on the upgrade of Mac 14 things are not the same. Buffering has or could be a big problem without Clean My Mac. I also realize that buffering can be a problem of too many open tabs or programs running in the background. I have deleted and turned off everything but what is needed to make it open up and run.
Nothing helps, the crux of the problem is with Yellow Mail it will not open up just the small circle that keeps turning. Thanks for listing. Carl
You just saved me 3000bucks by this tutorial thank you
Great video. Thank you. After installing SSD can we delete/format original HDD and use it for something?
Keep it up Mr Macintosh 👌
This was the video I was waiting for. You are the best! I have a 2014 macbook pro and a 2014 27” iMac. Both stuck on Big Sur. Been very undecided on what to do. I was thinking about trying this first. Not sure about Monterey or Ventura or even Sonoma. Do you have any recommendations?
I got Monterey installed on an external USB 3 ssd on my 2012 imac and it works fine BUT reboots are super slow (almost 10 min). Had to revert back to Catalina and reboots are a minute or 2. Wish I could figure this out.
Many thanks for this wonderful tutorial. Worked perfectly. I did an upgrade but my logic pro x now doesn't boot up. Is there a patch or solution for this? Also my final cut pro is requesting I buy a new license . Is there a patch or work around to fix these urgent issues?
Thanks a lot for shaing !
Thanks for your instructions they are on point. Howerever, I have a problem with my 2010 mac doing the final boot up. Any advice?
Many thanks for this great tutorial. I did an upgrade and it worked perfectly. However, my LOGIC PRO X is no longer working and my FINAL CUT PRO is requesting a new license. Is there a patch or solution around these? I need to sort them out urgently. Thanks
just spent 4 hours trying to install this onto a usb drive, just keeps re-booting doing same install over again, waste of time really, just glad it hasnt ruined my mac pro
Thank you so much for all the content, much appreciated!
I currently have a 2013 iMac with the 1TB fusion drive. Rather than taking it apart to upgrade the HD i have been using a crucial external SSD as my boot drive. Works awesome, but I'm stuck with Catalina. Does anyone know if OCLP installed with Sonoma or Ventura on the external SSD would work? and would i just leave the internal fusion drive as is? thanks in advance.
I’m so glad I DONT really need to watch these videos you make anymore. In the nicest way lol. Upgraded all my stuff to 2023/2024 systems. So I can take a few years off open core 🎉🎉. Still love ur videos man
Installing to an external USB drive: Now that I've installed to the USB drive, how do I delete the "Install" partition (or expand the Macintosh HD External) partition? It is taking up 25% of my external drive. How do I recover that space?
Please, looking for assistance. The instructions worked perfectly for me and I have the new OS on my external hard drive. Rather than moving on to the 2nd volume option I want to keep the new OS on my external drive for a few days. However whether I first shut down or restart and hold the option key I'm no longer able to access the new OS on my external. In summary what I'm trying to do is to be able to switch between my regular OS on my hard drive and the new OS on my external. I appreciate any assistance on how to do this, sincere thanks!
I would like to use the same USB across all types of Macs - Can you install the OCLP as to use for any Macs or do you have to specify the build beforehand? I followed everything, but wanted to use this same setup from a MacBook Air 2013 to a MacBook Pro 2013.
When I watch this video, the currently available OCLP version is 1.2.1 and macOS version is Sonoma 14.1.1. But my successful experiences vary in Sonoma 14.0, 14.1 and 14.1.1 on internal and external SSD start up drives. The worst case so far has been the MacBookPro13,2 (Late 2012) where the internal SSD can use Sonoma 14.0 and external SSD fails to start up Sonoma 14.1.1 and not even able to do Recovery 14.1.1 (dmg) after EFI 14.1.1. (same versions of KDK applied and Ethernet cable / usb-c adapter connected)
great work allways view your posts ... question i have got sonoma on main drive on mac mini i7 2012 i also have monterey on usb drive works treat if i put in mac internally will it still boot up like it does on usb or is usb boot install os only gonna work via usb
keep the expert knowledge flowing
Thank you very much, I updated my imac 2011 perfectly. I need to know if there is a way to update my old Ipad2, any tips, any tutorials?
**Excellent video** Is it possible to repeat this process and install 2 additional macos on 2 additional partitions, from 2 additional thumb drives? TIA
I loved you video and your patience and positive attitude and genuine passion for the subject matter, but I am sorry to say I spent 10 hours over and over with your video and I cannot get os Monterey installed on my MP3,, 1. I cannot get passed this infinite loop to keep reinstalling Monterey over and over again. it just refuses to cooperate or even to toss me a freaking bone
Thanks a lot for this video, very useful ! I have one question. Is it possible to keep one Volume with Monterey and one volume with Sonoma on the same disk (with a Mac Pro 2013) ? Thanks for your advice.
I think I will be listening more too you 😮
Thank you I have been looking for this one 🎉😊
heh. Couple of months ago I removed my main SSD with OCLP Ventura from my mbp late 2011. I replaced it with a brand new SSD and installed linux mint on it. After couple of months on linux mint, I thought it would be nice to have a dual boot. I bought an optibay and put Ventura SSD onto it. Then I realized it won't be that easy to just boot into Ventura.
Besides, it turned out, linux makes it somewhat tricky to access APFS volumes.
I'm wondering, is this tutorial suitable for such cases as mine, or it is just for installing from scratch?
I had to boot from external for my every day use because my 2018 Mac mini only came with 256gb and I can’t increase it. Having kernel panic issues after using open core for the past 12 months. But it had been fine off the usb c
Amazing!!! Thank u love the detailed video
Mine won't let me download into my new partition. It is grey and only gives me the option to select external hard drive
Excellent video tutorial ... 👍
it's interesting you are using an older version of OCLP for this tutorial. was there a reason to not use the newest OCLP?
It’s useful, thanks!
If I install MacOS via Opencore on an external SSD via USB, will TRIM be enabled? Or can't it be enabled via USB?
How to remove installation partition from USB drive to keep only macOS on external drive?
Thank you for this video Mr Mackintosh, I tried this to load Ventura on a MacMini 2014 + Magic keyboard and mouse, Main OS is Ventura OCLP 1.2, could get to 1st Reboot and screen displayed both internal drives but keyboard/mouse not connected - is this just a case of resetting NVRAM and PRAM per issue 251? or do I need to buy a wired mac keyboard? Alternatively should I install Monterey on the USB disk first?
Noob question: I understand option-boot, but what does holding option do when selecting EFI Boot?
Thanks for this very helpful tutorial. I’ve been running Monterey on a Mac Pro 5,1 using both ssd and a Samsung nvme, using clover configurator. I wanted to update and transfer to open core patcher so installed Ventura on another ssd using oc from my mbp pro 2015. All worked great, rebooted fine through the mbp. I then placed the drive in my Mac Pro but it wouldn’t boot. Can you or do you know why that may be? Thanks
If you have configured OCLP on and for a Macbook Pro, it will not be compatible with a Mac Pro.
This is great. Thank you!
Failed for my iMac (Retina 5K, 27'', ultimo 2014, FusionDrive). Following all the steps, but never get an option to select my external SSD. Everything runs fine up to 14:18 Min. SSD is formatted Mac OS Extended (journaled). Think there is a problem with the OCLP Bootloader (1.4.3) under Big Sur.
Does this work on a FireWire connected external drive?
Hi, Mr. Macintosh. Right at the end of the instructions you emphasize that the dual boot will work with a native macOS as the 1st partition - just as we saw it in your video. But while watching I was asking myself if this kind of Dual Boot also works, if the 1st partition already has installed an unsupported macOS? To be exact: I have a MBP 2011 running (unsupported) 10.15 Catalina. Is it possible to install a 2nd unsupported macOS on this internal SSD? Thank you in advance.
Very useful. Thanks for sharing.
@Mr.Macintosh Need your help/ideas
Whenever I have two macOS versions installed on my unsupported MacBook Pro with OCLP, I always have the problem that iCloud displays a issue when I switch from one system to the other and I have to log in to iCloud again each time.
This happens every time I switch from one macOS version to another.
I currently have macOS 14.7 installed on the internal SSD and macOS 15.0 installed on the external SSD (Samsung T7) the day before yesterday. I need the same Apple-ID on both macOS.
👉🏻 Is there a solution to this?
Successfully running Ventura on my old late 2013 iMac on an external SSD. However, my Zoom TAC-8 Thunderbolt device is not working. System Report shows it under "Thunderbolt/USB4" and as "connected". Just booted into Catalina, and it's working fine there, and the System Report seems to show the same info (TAC-8 as connected). I've re-installed all the TAC-8 drivers, but nothing worked. I could try a clean install of Ventura, but wondering if anybody is using Thunderbolt?
Maybe you can make a video how to instal windows 10 to external usb drive and play from usb i got macbook air 2012 5.2 13 inch when i unstal windows 10 graphic card make screen go black i watch so many video and no one didnt show propaply never work
Do you follow the same steps if you have a 2012 Mac mini with two internal hard drives? I would like to leave the original fusion HDD alone, and install OCLP/MacOS Sonoma on my recently purchased SSD. Now when you add the 1.3.0 OCLP update into the mix, it just leaves me confused. Please help Mr. McIntosh for I do not know where to begin!
I have an iMac late 2013 with 1tb HDD which i don't want to open to upgrade to SSD. Can i use this method to install an external SSD with USB 3.0 and have very good speeds?
HELP!!I have made two drives, one with High Sierra and one with Big Sur, I tested them on my 2013 Mac Book pro and they work fine, when I put them on my 2009 Imac, the High Sierra loads but no keyboard and mouse. The Big Sur begins to load and then half way stops. Any help would be appreciated, please and thank you.
what do i do if holding option to see boot options wont work?? have tried everything, cant find a solution...
I don't know what I'm doing wrong, but booting from external drive fails for me on Mac Mini 2012 (macmini6,2). Tried from SD card, from an external SSD, issue is the same. It's a shame because the machine is still great, but the internal hard drive is as slow as it gets. Is there anything one can do to force boot from external drive? I even tried Carbon Copy Cloner after installing successfully to the internal drive, to copy the entire contents of the internal to the external drive (external drive still shows up and bootable since I tried installing the OS there). But it doesn't get pass the boot screen.
Wowww amazing video. Thanks.
Thanks for the tutorial. This is my first OCLP install, I did Big Sur on a mid-2010 MBP, and it seems to have gone perfectly.
1 Question Please: After I option-click EFI Boot, I'm seeing extra USB drives with crazy names like "___~ks ujV_" and "_______p0_D@l". Are these an issue? If so, how do I kill them? Thanks
Installed Sonoma on my mid 2011 imac 27" and bluetooth is not working. How do i fix that?
This was awesome, thankyou.
My OCLP-Intaller gets to 307 mb and then stops. i tried a 128gb flash drive and a 240gb ssd. both stopped in the same area it sted thaat i dont have permission to save file.
Thank you! I have a question: I have a 2015 MBP with OS X 10.11 El Capitan, but I’d like to test Monterey (officially supported on my Mac, so no need to use OCLP) on an external SSD, but I’m afraid that the boot selector tool won’t detect the SSD after the installation, since El Capitan cannot read APFS volumes. Is this possible or do I need to upgrade to High Sierra before?
Is 14.2 going to break OCLP? Should I wait until 14.2 dust settles?
Hello, thank you for this video ! I wanted to follow your procedure but I got stuck creating the USB key with the following message: Error:2023-12-26 13:19:01.291 OpenCore-
Patcher8264:44266] Starting./Volumes/OCLP-Installer is not a valid volume mount point. Have you ever seen this type of message? Thank you. Daniel
If you want to keep the updated OS via OCLP and delete the original supported OS can you simply delete that partition instead of the OCLP partition?
Great JOB !
Hey Mr Mac. I have just put Ventura on my imac 2013 but now replacing it and need to clear all my info and can't find anything to allow me to reinstall Ventura , can you help how do I wipe it clean?
I follow all steps but when it came to hold down option key to select the usb startup disc with ventura instaler and partioned .. it just doesnt show it. I can see it on my desktop and in disk utility but not as an option to startup.
help please.
thanks
Mr.Macintosh, it is very important for me to uprade my Macbook Pro Retina 15" mid 2012 to Ventura.Currently running Mojave. Using external drive backed up with SuperDuper I am trying to use my backup done by SuperDuper but boot software cannot do it since the backup is not in APFS format. Is the upgrade a good option. If the compatibility list says Macbook Pro does it mean it include my Retina model. Would really appreciate your help in this matter.
ive done this exactly the same more than 10 times, from updating to clean install and when i reboot, i never get the efi pop up to say that sonomo is available to install. it always greys out the install. ive looked online, ive asked people. ive got nothing in return.
Bro if this works good man I will subscribe. I was having issues
i've manage to install ventura on my old hp desktop pc by downloading a copy of olarila ventura from their website along with one of their haswell efi folders everything works well except for wifi and sound i haven't figured it out yet i wanted to try patching a few things up so i decided to install oclp everything went fine according to your video but after finishing up i don't have the option to boot into oclp boot menu i guess because i'm using an unsupported pc that's only designed to run windows is it anyway possible to get oclp boot-menu from my hp "thanks"
I have a windows partition on my drive, can I still use this upgrade? Thanks.
Nicely explained!
Big question: I run Monterey on my Mid11 iMac. It works mostly and to be safe for the business I have to stick to it. But I miss certain things, as not all works well or even at all on Monterey. It seems it should be possible to create a dual boot with High Sierra as the secondary system. But: Do I have to erase all and start with High Sierra first and add Monterey, or can I keep Monterey an add High Sierra. How to format the High Sierra partition? Will it work on APFS - then I could only add a volume, correct? - or do I have to make it macOS Extended (journaled)?
extended journaled, it will change to apts buy itself,,hope this helped
@@stephencawker1565 thanks. I'l try this.
@@LernGuru Ok, Thanks Lern!.Its the best one, ive been studying this..
can you post the results please....
Black magic speed test.if you have 2015 or newer it will be faster.Mr macintosh is very busy guy..lol
@@stephencawker1565 I wanted to partition from inside of Monterey but got an information that it may take forever and it should be significantly faster to partition from the recovery in the installer. This however did not work. So, I went back to Monterey, bit in the bitter apple - pardon the pun - and created a partition for High Sierra with the format You suggested. Presently, High Sierra is installing on its partition. I will let You know, when it's done.
As promised: it worked. Thanks Stephen.
If you install it on your main hard drive does it erase your old data?
