omarchy mac installer on M2/M3 macs: resize and partitioning go through, then the engine quits at "Writing boot files" with diskUnchanged: false, so the partitions stay behind. 2.3.16 was supposed to sort out the ._ AppleDouble files on the EFI partition but it still fails the same way, and macOS 27.2 doesn't help.

Edge channel in the installer menu is what gets around it. That pulls the newer 0.9.2 engine instead of the stale one, and two M3 Max owners on the github issue confirmed it boots. Go back to Stable inside omarchy after.
