400 MHz iMac DV (Late 1999)

Kikei iMacDevelopment of the “Kihei” iMac began the day after the first iMac shipped. The new model is an evolutionary development of Apple’s 2,000,000 unit seller.

The first iMacs with a DVD-ROM drive, the iMac DV  and DV SE run a lightning fast 400 MHz G3 processor on a 100 MHz system bus and are the first iMacs with FireWire. The slot-loading drive protects the drive mechanism, while the new Harman Kardon sound system improves audio output. (HK released a complementary subwoofer in November.)

The RAGE 128 graphics and 2x AGP give it superior graphics performance, and the VGA port allows using an external monitor or LCD projector.

Available in the same five colors as the Revision C and Revision D iMacs, the DV is a bit smaller and has more transparent plastics. The new case allows the iMac to air cool (just like the old Volkswagen Beetle), eliminating the need for a cooling fan.

  • 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.

  • 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.
