===== Notes =====

  * :!: Booting macOS ((any media: Internal HDD, USB, CD/optical, 10.4 install CD and Sorbet Leopard)) from OpenFirmware or ''Option''-key-hold boot menu causes corrupted graphics ((CD/optical boot with ''C''-key-hold is fine))
  * :!: 10.4 Tiger requires an external mouse for install ((touchpad isn't native-supported on base ''10.4'' but works on ''10.4.11'' and out-the-box Sorbet Leopard))
  * Disk Utility has a long delay with loading disk info if internal HDD is formatted ''Unix File System'' (not Mac OS Extended)

====== Sorbet Leopard ======

  * https://macintoshgarden.org/apps/sorbet-leopard
  * https://lifedigital2010.wordpress.com/2011/04/03/how-to-install-mac-osx-from-usb-on-powerbook-g4/
  * Sorbet Leopard copies to USB as a pre-installed OS ((LiveUSB-style with persistence; doesn't present an installer to install to internal HDD))
  * Carbon Copy Cloner (CCC) can be used to restore an OS-mounted Sorbet dmg to internal HDD ((the restore from image option in CCC didn't work; had high resource load trying to mount 5+ minutes))

  * Internal HDD install: Copy to USB -> boot Sorbet Leopard from USB -> restore USB to internal HDD (Disk Utility) -> Fix permissions -> Reboot into HDD install
