What's the oldest version of MacOS that I could reinstall on Apple silicon?

[–] [email protected] 10 points 9 months ago

That depends on your Mac. The older the Mac, the older the version. On most M1 Macs, you can go back even to Big Sur, on M2 it's usually Monterey and so on. It might be different with the Pro/Max/Ultra variants though.

More important question for me:

what is the oldest MacOS with xcode support (and therefore oldest I can run brew on)?

I keep meaning to figure this out.

I believe brew dropped support for a high Sierra just a couple years back (2022 I think) but as of now my 2012 MacBook Pro is still chugging along whenever I need to compile or test something for x86 and can't be bothered to cross-compile from my new MacBook :)

This version naming is hrllaripusly awful. "It works on rotund tundra, but not alpine fresh. Hope that helps!"

Hehe, I absolutely agree.. for reference, High Sierra is v10.13, released in 2017. I'm now running v13, released 2022. They moved from v10.15 to v11 in 2020, when the arm chips were released.

My old MacBook could probably run 10.15 just fine, but I don't have any good reason to update it, as it's only purpose now is to compile distributables for other old machines.

Also: I really dislike that they've been pushing non-backwards compatible major releases so hard since 2020. I'm not updating my OS because I can't be bothered to break shit, it shouldn't be like that..
