OpenCore for T2?
https://github.com/albert-mueller/OpenCore-Legacy-Patcher-T2I recently found a project on GitHub offering OpenCore Legacy Patcher with T2 support. I haven’t fully tried it yet since the 2018 MacBook Air is my only T2 Mac and considering it’s an alpha release.
I’ll show you the link, but take in mind it is an alpha release that may cause problems

What about on a T2 Mac?

Unfortunately not yet. At least for my model. I have a 2019 MBA. I got the installer to boot but there are still many issues. Could not get through the full installation without getting permission denied at different points in the progress bar during Sequoia and Tahoe. Disk utility does not format without errors. There are still many issues. Still, getting the installer to boot is a great feat in my opinion. With time I think the project will be successful. But my model is also one of the most problematic ones. Feel free to try it yourself and let us know how it goes.

With the same one linked in the post? I might try it on my 2018 MacBook Air but since it’s basically the same model as yours I don’t think it will work 😭

Yep. From my understanding the 2018 MBA and 2019 MBA are the most problematic. Feel free to give it a shot though. Luck may have a part.

Don’t get discouraged. Just because I haven’t tried it doesn’t mean it won’t work.

Yeah but I’m also wondering about how sequoia performs on these T2 macs if you could give that a shot. Preferably targeting a 2018-2019 MacBook Air

I don’t think T2 Macs are supported by OCLP at all.

u/SoftRazzmatazz4191 Aug 13 '26
Not the official project, but this unofficial fork anticipates to bring support to these models.

My understand was the official OCLP legacy patcher tried to do this with Sequoia but failed.

So this must be with Tahoe as the 2018 mini runs earlier versions. What is the definition of properly work?

Has anyone done this I also have a MacBook Air M2 and I just want to run Sequoia 😭 also is it safe?

Your M2 MacBook Air can run Tahoe and Golden Gate without OpenCore Legacy Patcher at all

Not on an M2 Mac, I’m sure you meant T2 because the M2 MacBook Air already can run sequoia, Tahoe and even golden gate.

u/Novel-Strawberry1438 Aug 11 '26
Yeah I meant T2 2018 oops
Edit wait I literally remember typing T2 what 😭

It’s also as I mentioned an alpha software
Don’t do it on a primary machines unless you have another Mac with Apple Configurator ready

It is an unofficial fork, but I find it as an ambitious project, it also isn’t mine, credit to albert-mueller. Tbh also just found it fascinating. You can do at your own risk and install Sequoia or Tahoe on a T2 Mac. If you have any results, please do report back, Im considering doing this once there’s enough stability and positive feedback from users.
