600 MHz iMac (Summer 2001)

The July 2001 iMac came in speeds of 500, 600, and 700 MHz, although the 700 wasn’t available until August.

All models included CD-RW drives and at least 128 MB of RAM. Except for the $799 model, only available in indigo, each version was available in snow (white). The 500 MHz models were available in indigo, and the faster two models were also available in graphite.

A special 64 MB/CD-ROM version was released at $799 in September 2001. This is the same as the education model Apple had been selling since July 2001.

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

  • 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.
  • 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.
  • 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 earlier Macs which use it from ROM. You lose the use of 3 MB of memory but gain faster performance.
