Grub Bug?? I think. Dual booting Macbook pro Arch/mac os big sur

I'd like to preface this post that I can get everything to work normally, but I have to select the booting option by holding the alt/option key on my 2013 Macbook pro. Upon cold start the grub menu normally comes up with Arch linux or Macosx as a bootable option. Selecting Archlinux boots it normally as expected. Selecting Macosx boots until an error window is reached. It indicates that there is a problem with the selected drive and requires a reboot. It refuses to boot from the grub menu and will only boot if I press and hold the option key and manually select the Macosx partition. Now generally, this doesn't really bother me that much, I have a work around, but I'm just wondering if someone else has encountered this issue.

It's a known limitation.  According to a few notes in the wiki, you cannot dual boot arch + macOS both via GRUB - or more specifically, MacOS can't be booted via GRUB:

I'd ditch grub and use another boot manager - but another wiki page suggest that using grubs --removable flag might get this working.
