Plans to support macOS Monterey? #133

Closed benmwebb closed 2 years ago

benmwebb commented 2 years ago

Any plans to support installation of macOS 12 (Monterey) on Intel? Or perhaps it's not possible for reasons outside of your control (maybe VirtualBox doesn't support it)?

In my limited testing (I am happy to help) installinstallmacos.py was able to download the installer, but installation failed because while apfs.efi appeared to find a new filesystem, it wasn't able to find any files on it so couldn't boot from it.

Good point. I started testing it:

Seems I don't run into the apfs.efi issue (for macOS 12 on macOS 12), however, I sometimes run into kernel panics. As it works for others it's probably just a question of the VM configuration.

Yes, I should have said this was on a Catalina host. On a Big Sur host I see the same as you - the installer starts up, but panics long before the installation can complete.

Those Monterey guest kernel panics can be fixed if you apply the following setting to the VM:

VBoxManage setextradata "macOS-VM" "VBoxInternal/TM/TSCMode" "RealTSCOffset"

Although I found that fix mentioned in several places, I couldn't find an explanation of why it fixes it but I'm not complaining since it now works 😄
