Gentoo Forums

• I should NOT use the Apple (gui) disk manager to do anything, but instead Apple's diskutil cli tool.

  Yeah... Apple really didn't make this easy. But at least they didn't forbid from booting other OSes.

Since you need to keep the first and last partition in place, that means most disk management operations from Linux will append partitions to the GPT, and put it out of order. Make sure you fix this. With the fdisk Linux command this can be done with x (go into expert mode) → f (fix partitions order) → r (return to main menu) → w (write changes and exit).

  ... So I will definitely have one EFI partition and one partition dedicated to lvm, so I don't need to worry too much.

• Well... I got rid of the correct partitions/containers. I left the first, last and the macOS disk image intact. The first and last are essential to boot and to be able to boot into recovery OS. I guess the macOS disk image isn't needed because it contains only the installer.
  But at this point the Asahi installed wouldn't continue after the first key press. It complained that the Mac didn't have any bootable macOSes. The thing I just wanted. The Asahi installer needs a macOS to be able to authenticate when modifying some boot parameters, I guess.
  Now the question is can I remove the macOS container after I have booted Gentoo live medium? I wish to be able to get along only with the Recovery OS (first and last container/partition).
  I'm currently reinstalling macOS... That'll take hours...

Re: RecoveryOS vs your main macOS install, the main macOS install is by default the "machine ower" in regards to the SEP, so no, RecoveryOS cannot directly replace it.

The problem is your system firmware. Getting the files is easy, we know how to do that, but nobody knows how to install them without macOS to do it.

Plus as I said the SEP machine owner user management. If you delete macOS, you are deleting the credential store for the only administrator as far as the machine is concerned. That means no more managing the Asahi install from the machine's perspective. Which means no bootloader updates, no recovery, no reinstalls, etc.

We tell people not to delete macOS for very good reasons. Yes, we know lots of people want to delete it. If this were an easy problem to solve we would have solved it already.
