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

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?
