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

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.
