Does dmidecode work, and produce any useful information? Is there anything under /sys that might be able to tell that the kernel is running on Apple hardware?

If so, I'd like to use this to be able to automatically skip the menu that asks if efibootmgr should install an EFI boot entry. It warns not to do it on a Mac, but I'd rather not give anyone the opportunity to shoot themselves in the foot. Especially because it's a pretty bad foot bullet that bricks the firmware, and would mean the machine would have to be sent in for service.

Any help appreciated.

Maybe a dumb idea but...

If Mac OS is installed and UEFI enabled, according to man bless, there should be a file /usr/standalone/i386/boot.efi. So maybe probe the existing partitions and check if it's there? Maybe you could have a look at this thread if not already done.

Of course that won't work if user wiped out all existing partitions before running setup...

You can probe /sys/class/dmi/id/sys_vendor and compare to "Apple Inc." and "Apple Computer, Inc.".
