No, but I think it’s unlikely that Apple actually has this information in a format that it could easily publicly release. They aren’t going to make any special effort to make Linux on Mac easier, but they also aren’t actively blocking it.

Well, I was more talking about the fact that you can still install Windows 11 on an Intel Mac right now; the drivers are still there for those few Intel macs still supported.

As for Windows on ARM, I'd bet that if Microsoft had managed to figure out their own product, Apple might have been tempted to support it. I mean why go through all the trouble of developing the most advanced firmware on the planet to support a fully secure macOS next to an unsecured OS if you do nothing with it?
