A Limited Mac

Blueberry 350 MHz iMacAt 350 MHz, it may not seem a whole lot faster than the Revision D iMac, but the new “Kihei” iMac uses a 100 MHz system bus – plus RAGE 128 graphics and 2X AGP for superior video performance.

In addition to regular iMac features, the new iMac has two separate USB controllers and room for an AirPort card.

The new iMac is slightly smaller and about three pounds lighter than the earlier models.

  • 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.

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.
  • Update Firmware Before Installing Jaguar!, Geoff Duncan, TidBITS, 2002.10.28. If your firmware isn’t at version 4.1.9, you need to boot into OS 9.1 and install it before attempting to install Jaguar (OS X 10.3) on your slot-loading CD-ROM or DVD iMac.
  • You must have the keyboard plugged directly into an iMac USB port to boot with the power key; it will not work if the keyboard is attached to a hub.
  • You cannot boot the iMac from an external USB drive.
  • 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.
