Remarks

Macos Catalina

  • Erase/format the MAC HD/SSD before installation !! I really think that this does it more simple for the installer !!
    • With an old non SSD HD use 'Mac OS Extended(journaled)'
    • 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 !!!
  • In TUI '5. Miscellaneous Settings => 1. Set Showpicker Mode:' was set to 'False'
