Remarks
Mac Os Big Sur Download
- 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 !!!
