FreeBSD in Parallels
How to avoid a kernel panic when installing FreeBSD under Parallels
I was experiencing an issue trying to install FreeBSD 12.1 under Parallels on my MacBook Air where the kernel would panic immediately upon boot. A quick search of the Parallels forums returned this helpful thread.
TL;DR: The FreeBSD boot loaded needs to be told to expect an EFI BIOS, so set vm.bios.efi = 1
in the boot order settings.
Thanks Kaoru!
