Mac OS X

Non-Apple upgrades and peripherals (such as unsupported USB devices, replacement drives, and third-party memory) may cause problems when installing or booting into Mac OS X.

Cautions

  • G3 Macs may not be supported in Mac OS X 10.5 “Leopard”, which is scheduled to ship in October. Apple has not spoken on the record, but the beta cannot be installed on any G3 Mac.
  • You cannot plug the iPod shuffle directly into the iMac’s USB port – it will not fit. It will not charge if plugged into a keyboard USB port or an unpowered USB hub. To charge it while using it with your iMac, you must us a USB extension cable, powered USB hub, iPod shuffle dock, or a USB power adapter.
  • OS X: Macworld UK noted on 2001.03.28 that the OS 9.1 CD included with OS X will not install on the PowerBook G4, Power Mac G4 (133 MHz bus), or 2001 iMacs. The solution is to use the Mac OS 9.1 CD that came with the computer.
  • You must have the keyboard plugged directly into an iMac USB port to boot with the power key (Eject on the Apple Pro Keyboard); it will not work if the keyboard is attached to a hub.
  • The iMac loads the MacOS Toolbox into RAM, unlike other Macs which use it from ROM. You lose the use of 3 MB of memory but gain faster performance.
