  • 500 MHz 256 KB on-chip cache, not 200 MHz 512 KB backside cache
  • ATI Rage 128 Ultra, not older Rage 128 Pro
  • 16 MB video memory, not 8 MB

Mac OS 9

  • If you are running Mac OS 9.1 or later, iMac Firmware Update 4.1.9 should be installed. If you are using Mac OS X, you must boot from a Mac OS 9.1-9.2.2 writeable partition (not a CD or network disk) prior to updating. You cannot update to OS X 10.3 or later unless you first install Firmware Update 4.1.9.
  • For more information on firmware updates, see iMac: When to Install Available Updaters.

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.

Be sure to read and follow Apple’s “Read Before You Install” install instructions to increase the likelihood of getting OS X installed and running on the first try.

Cautions

  • 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.
  • iMacs released in February 2001 and July 2001 should have iMac Power Management Update 1.1 installed to solve a problem with losing PRAM settings when the computer is disconnected from power for an extended period of time. See Knowledge Base article 120048 for full details.
  • 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.
