Issue/Bug Description:
The installation fails to finish. Installation fails.
installer.log

Steps to reproduce (if you know):
Attempt to install Pop!_OS on a 21.5 inch 2011 iMac

Expected behavior:
Successful installation

Other Notes:
Issue occurs on both custom and clean install.

[pacman-admin]

It appears Pop!_OS deletes the Apple UEFI partition when Clean install is selected.
This renders the system non-bootable.

[pacman-admin]

Clean install should preserve EFI system partitions.
Rescatux cannot fix the issue.
I had to use disk utility(on a bootable MacOS installer) to reformat the drive as HFS+ and do a custom install.

It wouldn't be a clean install if it was preserving a partition, including the ESP. On UEFI-compliant computers, the ESP that the Pop!_OS installer creates should work. I understand Apple's EFI implementation can work differently.

Were you able to identify the difference between the default Pop!_OS ESP and the working one from macOS?
