Mac Os Big Sur Compatibility

Remarks

Erase/format the MAC HD/SSD before installation !! I really think that this does it more simple for the installer !!

'Mac OS Extended(journaled)' with an old non SSD HD
With en SSD use 'APFS'

The Mac rebooted several times during install.

Don't remove the USB until at the very end.

If you, like me, have a Mac which need the legacy video acceleration support please note that the Mac have a painfully slow display update before you have applied the 'Post-Install volume Patch'.

Updating the Mac from Big Sur 11.4 to 11.5, made the messages.app stop working fixed in release 0.2.4

Please note that 'Nightly Builds' are available but are for testing purposes only !!!
