OpenCore Legacy Patcher overview
OpenCore is a sophisticated boot loader used to inject and patch data in memory, instead of on disk. This means that we're able to achieve a near-native experience on many unsupported Macs.
Built with security in mind
Supporting System Integrity Protection(SIP), FileVault 2, .im4m Secure Boot and Vaulting. For many machines, you're just as secure as a supported Mac.
Native OTA updates
Install updates the moment they come out, with native System Preferences support, just like a supported Mac.
Zero firmware patching
Using the capabilities of the OpenCore boot manager, our protocol upgrades are done in memory and are never permanent.
Supporting more hardware
New life is breathed into your decade-old graphics card or WiFi and bluetooth chipsets.
The newest features
Unlock Sidecar, AirPlay to Mac, Night Shift, and Universal Control, even on natively supported models!
A helpful community
Whether it's getting started or learning the specifics, you can always find answers with our amazing community of tinkerers, developers, and dreamers.

Version: 1.4.1
I would love to upgrade my late 2013 iMac to a more recent MacOs. By the same token I still require to boot from an external disk that runs Mojave because of legacy software. I tested the boot drive on a 2020 Intel macbook and an M1 macbook both running Sonoma. Both macbooks did not allow a boot into MacOs Mojave. Is this an architecture (M1) problem or is Mac Sonoma too new. Who knows which MacOs if legacy patched would still allow me to boot into Mojave?
Second question: Once the newer MacOs is running on the old machine, how will security updates be handled that Apples distributes now and then?

Hello, I made a big mistake by not updating OpenCore to 1.41 instead of the 1.3. Now I can't use the mouse or keyboard. Is there a way to fix it?
Thanks,
Jim

Version: 1.2.1
Have a IMAC 15.1, picked up the open-core to be able push IOS to Sonoma. Needed Parallels 19 with windows 11 to reinstall my quickbooks. Noticed with the current graphics patch with the virtual machine my windows11 screens are blank. Ran through tech support with parallels for a good hour or so and they could not fix the glitch unless in windows the videocontroller is disabled. Assuming the opencore patch used to push the IOS to Sonoma parallels is unable to read. I guess a patch on top of a VM patch is creating the issue?
-Any known fixes for this? I can keep the video disabled but blocks me from running in coherent which I really like, also when in windows have to control/alt to release my cursor to drop back into my mac, kind of a pain in the a@@.

The developer website is riddled with entreaties to download and install malware. Whether this is intentional or the site has been hacked doesn't really matter--in either case this app should not be considered safe. I poked around in the contents of the app and didn't find anything immediately untoward, but there are a couple of encrypted disk images in there so... IMHO, between the encrypted app contents and the malware on the website one should stay afar way from this until it is demonstrated to be safe.

Hi: I have a problem in that my iMac Retina 5K has no internet connection. Has anyone tried downloading OCLP for a Mac to a USB storage device on a Windows system, then using that download on the Mac to install the current OCLP on the Mac ? Could this approach work?

I am really keen on using oclp for updating my Imac 11-3 to more current OS. it went all fine untill I had to selelct the target Drive for installing the new OS. In my case this is an SSD, samsung 2 Tb. It appears that this destination drive is formatted as MAC OS extended journaled. so is my additoanl HDD for backing up my system by using TIme machine.
What I can find on the internet is that Time machine cannot work with FAT.
As it is unlcear to me on how to proceed: Any suggestions on how I can use oclp for installing more recent MAC OS given the above configuration?

Hey there. I’ve got a quick question, I recently installed Mac OS Monterey on my 2010 Mac Pro. It runs like new and I can install more software for Music Production and Editing.
My question is this now: I bought an audio interface which is Thunderbolt 3 and was going to buy a Thunderbolt 3 PCIe card to in order to run this piece of gear, but I’m not sure if it work as all the info seems to suggest it won’t though I’m not sure those people have OPEN CORE LEGACY PATCHER running on their machines.
Any info on this would be greatly appreciated as I am now considering sending the interface back

I've got OCLP 0.6.1 installed on 3 machines -- a mid-2009 15" MacBook Pro, a 2011 Mac Mini, and a mid-2011 MacBook Air. All running MacOS Monterey 12.6.3 flawlessly. The work the Dortania team did on this is truly incredible. Yes you'll lose 32-bit applications but if your workflow relies on them, don't upgrade. But for me, I can now use the "current" version of Pages, Keynote, and Numbers interchangably on a whole bunch of Macs in different locations -- which simplifies my life significantly. Thanks guys!

WARNING TO YOU USERS THAT HAVE A MAC STILL CAPABLE OF RUNNING 32-BIT APPLICATIONS -- if you upgrade to Monterey or Ventura, you will LOSE QuickTime Pro -- just one of the INVALUABLE applications still 32-bit native only - also, Tex-Edit Plus, and many others. I say to you - DO NOT DO IT. Apple has screwed us big time by forcing 64-bit without recourse on its customers! Mac OS 12 and 13 brings nothing valuable to the table in real-life.

I tried this on my late 2014 MacMini. I managed to install Ventura following the detailed instruction on the developers website. Unfortunately my Internet failed to work. I thought at one point that I had totally mucked up my Mac. I then was inspired to do a fresh install from the USB stick with the Ventura previously downloaded from the developers website. It worked. I was also able to download Ventura 16.2 from Apple and it works very well. This app has given my Mac mini a new lease of life and gives me the latest Apple updates and I no longer have to think about buying a new Mac mini.A great app.

My second comment on this app is that they must repair a big bug in Monterey, because if you look at the supported models and you see that Ventura is not supported why does i see that i can upgrade to Ventura in the updatebox in Monterey ? I hope they fix this but i think a developer does not read this ! This is a bug in the opencoreapp and is not ok !

OPenCore Legacy Patcher. Wow. Beware. It essentially bricked my mbp 2013. If you go to github to report a bug you will find that the lead developer has turned off bug reporting and has basically quit the project. Incredibly improper. The guy should state this on the landing page for OpenCore. So basically I got the opencore legacy patcher to install, I rebooted, followed the instructions to boot to the correct partition, and whoa, the keyboard will only allow certain characters for the password input. I tried a USB keyboard too: I can't enter password. So I am stuck in an infinite loop. Recovery boot allows me to reset my password to use a few keys that still work on the keyboard...but then this horrible software states my password is incorrect. If I could submit a bug report, perhaps that would be ok. At this point I need to create a new boot stick and start over. What a garbage tool.

Well, if you download the app from the developer there is is bug in the newest version, i get a message that the installer was not valid………but there was a link in a magazine and that worked, now i have installed big sur because Ventura does not work on my old Macbook pro from late 2010 haha ! If you dowload Monterey you get a message in updates that you can upgrade to Ventura……..so i stick with Big Sur for now !
