Overview

The first iMac to reach 1 GHz, the 17" G4 iMac has a wide aspect ratio "cinema" type screen and displays 1440 by 900 pixels - just perfect for DVDs. Other improvements over the old 800 MHz model include a slot for an AirPort Extreme card, space for internal Bluetooth, 64 MB of video memory, a 133 MHz system bus, 4x DVD burning speed, and a 7200 rpm UltraATA/100 hard drive.

17-inch iMac G4

Some Leopard users have reported problems with G4 iMacs that have GeForce2 or GeForce4 graphics. When the system wakes from sleep, the screen will be completely white, making the computer unusable. This is fixed by Leopard Graphics Update 1.0, which requires OS X 10.5.2 or later.

Why you should partition your Mac's hard drive, Dan Knight, Mac Musings, 2008.12.11.
