I want to thank both Mykola Grymalyuk (khronokernel) & Dhinak G (dhinakg) for your work on OpenCore Legacy Patcher + all of the contributing developers that help maintain the patcher!
DISCLAIMER: Please understand that installing macOS Sonoma, Ventura, Monterey or Big Sur on your unsupported Mac is a best effort by the community. A ton of work went into getting the patcher to work! Some things might not work exactly right but it's really really close. I would not recommend installing Sonoma (use Ventura or Monterey) on a system that you rely on for work or school. ALWAYS BACKUP YOUR FILES FIRST BEFORE YOU UPGRADE! The good news is that you are getting the latest security fixes from Apple. Some might argue that upgrading OCLP makes your Mac safer since Apple is no longer fixing security issues on Big Sur and below. But this process is not supported by Apple and is to be used at your risk only.

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!

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. I truly feel that I have acquired a 2023 calculator.

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.

@lovebirdsmusic 6 месяцев назад

this is EXACTLY what i was looking for!!! thank you so much! also in its entirety - absolutely beautiful. amazingly explained! i´m a music producer for 30 years and since 2009 i´m running my beautiful mac pro 4.1. for me it was always important not to overwrite existing systems so i can always go back and open old logic arrangements exactly how they were. my latest system was 10.9.5. (i know, pretty old) but all i need is a running machine and not the latest updates. i just moved into a new studio with 2 friends and i want to update to a more modern OS so we can all run on a very similar system. tomorrow i´ll try to install mojave on my mac pro. i´ve also ordered a graphics card because i hears its necessary. i´ve installed a 4TB internal HD on a RAID slot (all HD slots were full). wish me luck))

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.

@RikerJoe 7 месяцев назад

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.

@uttarbajarange 7 месяцев назад

Hi, that tip which you mentioned about bypassing to hold Option Key, can you please share where is that exact option to do it OCLP app?

@DuckDuckDad 5 месяцев назад

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.

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.

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!!!!!

@BATsTM 7 месяцев назад

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.

@denniseldridge2936 7 месяцев назад

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 7 месяцев назад

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.

@denniseldridge2936 7 месяцев назад

@@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.

@sjn7220 7 месяцев назад

@@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.

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

@rm3934 6 месяцев назад

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.

@EzraODay 7 месяцев назад

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.

@cj28739 7 месяцев назад

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

@olivieradam4710 10 дней назад

@pmtate 6 месяцев назад

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?

@dwaynefilipchuk9518 5 месяцев назад

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 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.

@recalcitrantimbroglio 5 месяцев назад

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!

@ivanmytube 7 месяцев назад

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)

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.

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.

Is there a discord to get some help with this.? I've been trying for the last 2 days to patch my Mac Mini 2012 without success. Followed a variety of video tutorials but seem to be hitting a brick wall each time and worried I'm screwing up my Mac permanently. Followed this latest one today by installing onto an external SSD but even this drive is coming up with an error even after erasing in DIsk Utility multiple times. I managed to get it onto a USB drive yesterday but it was failing at the installing after selecting the Boot EFI at reboot. Starting to tear my hair out..any help would be massively appreciated

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.

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)?

@@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.

Hi. I have a MacBook Pro late 2011 with Big Sur on my main SSD with Open Core Patcher. I have a second SSD using caddy and would like to install High Sierra, but High Sierra is fully supported for my Mac and don't need Open Core to install. I managed to install High Sierra on the second SSD but after installation I can't boot on High Sierra, OCLP only show me Big Sur. Is there any way to leave the second SSD with High Sierra without having to go through the OpenCore Patcher and have it appear normally on the boot screen? Even with Option pressed I can't see the second SSD

@AlbertoGarcia-px9ml 4 месяца назад

Maybe I'm terribly mistaken, and if I am, please someone correct me. I also have a second internal HD in my MacBook mid 2012 but I never tried to install an OS there... would be great if I'm wrong and it is possible! I think you need to have all the Internal OSs in the "primary" (bootable) partition on the first disk. After you can have the OSs running in separate partitions or different volumes in that disk. The decision is important depending on what you're planning to do with your OSs in the future. As long as I understood it, you can boot from external drives (DVD, USB, network?...) OR an internal drive with the initial system boot partition (the one that OCLP patches) "serving" all the OSs in that disk. I don't think you're able to have two bootable partitions in two different internal disks and be able to chose between them when rebooting using the Option key pressed. It will only show external drives already attached and the OSs the initial boot partition on the first disk "manages".

Hi I seem to have problems after trying both installing OCLP/Sonoma (previous and latest versions ) to internal drive/ partitions. and both versions have issues playing Netflix/ prime video/ discovery +.. they give errors and won't play video. the Sonoma is fully up to date and as is OCLP after checking once installed Sonoma. I really prefer to use Safari if possible .. any ideas how to fix this .(ie Netflix error :S7706). Its very frustrating. (I have a 15.1 iMac) installs all went well. I even did a update from Big Sur and it went well also bar the video play backs.. any help would be appreciated
