Opencore-Legacy-Patcher VS big-sur-micropatcher

At a guess I would say probably using OCLP - https://github.com/dortania/OpenCore-Legacy-Patcher - lots of life left in old Mac’s using that tool !

I had this issue, too. But luckily, I've got a solution. First, you'll need to check your MacOS Sonoma version. If you're using 14.1 beta, this method will NOT work. In such cases, I recommend installing the official 14.0. Thankfully, this commit (https://github.com/dortania/OpenCore-Legacy-Patcher/commit/1aee2e5dfa12d10e218a51e4151ac2e96705ae9e) solved the problem! However, the latest OCLP 1.0.1 still doesn't have it. To use it, you can build OCLP from code or use the OCLP Nightly link found here. After you find the nightly link and download OCLP, build it onto your MBP, and after rebooting, install the patches. If you look carefully, you'll see that 'experimental T1 Patches' will be available in the list of post-installation patches.

From what I've assessed reading other posts, Monterey (Ventura has USB & stability issues) with OCLP 0.6.7 is the most stable install for this device (have not yet seen any reports using OCLP 1.0+, although happy to see some new non-Metal fixes going in). This is a bit of a bummer, as Monterey will not likely receive updates past end of 2024 (next year).

I'm not taking a position on OCLP being trustworthy or not, but at least the project appears to be 100% open source [0], which is more than we can say about Apple.

Have you explored https://github.com/dortania/OpenCore-Legacy-Patcher?

I have used it before and, in my experience and everyone else I know who has used it, the vast majority of time the newer versions run absolutely fine with no issues. Occasionally some newer features don't work, but I'd but confident that 2015/2017 iMacs would be able to run the latest version no problem.

I might have pushed my 2010 MacBook a bit too far. Back in 2020 I installed DosDude1's Catalina patcher on my 2010 Unibody MacBook and it worked great! Then, I learned of [this](https://github.com/barrykn/big-sur-micropatcher) new patcher tool that would enable my 2010 MacBook to run Big Sur, albeit slowly. Ever since then I've noticed some odd quirks about my machine. To clarify, it is still working, just not 100%.

I am trying to install from a USB, and am following this guide. https://github.com/barrykn/big-sur-micropatcher

Also you could check out the micropatcher , I used it before switching to patched Sur and it worked for me.

I’m running Big Sur on mine. It was a pretty simple process. I used this.

The link for the patcher is here.

Thanks for getting back to me. I created the usb using themicropatcher via another Mac as I previously used the usb to create the patch for Monterey. Should I try recreating the usb with patches Sur?
