Unsupported UtilityX is a utility which helps to install and boot Mac OS X, Mac OS X Server, and Darwin 1.4.1, on certain unsupported systems. The only difference from a supported installation is 3 extra clicks of your mouse.
The unsupported hardware that can work with Unsupported UtilityX is the 7300, 7500, 7600, 8500, 8600, 9500 and 9600, as well the clones that were based on one of these systems (the Umax S900 and J700, and the Power Computing PowerWave and PowerTowerPro).
The original 604 processor in these systems will work with Mac OS X. The 9500MP and 9600MP work, but only one processor is active at this time. G3 and G4 upgrade cards work, though you will need a utility to enable the L2 cache.Compatibility
Unsupported UtilityX requires Mac OS 9 (or later).
