Mac OS Support
OIT currently supports Macintosh computers running Mac OS X, the minimum OS is 10.3 or later on a G3 or higher processor. Mac OS 9.2.2 is not supported as a stand-alone operating system, only when used as Classic mode running under Mac OS X.
Apple does not support Mac OS 10.3 or later on any of the G3 Macintoshes that do not have built-in USB ports. The original beige G3 systems as well as the early G3 Powerbooks do not have built-in USB ports and are therefore no longer supported by OIT.Mac OS 10.4 will not install on systems that do not have built-in Firewire ports such as the early iMac computers and clamshell iBook.
Mac OS 10.5 will not install on any G3 Macintosh or any G4 Macintosh with a processor speed equal to or below 800 Mhz. Mac OS 10.5 also will not run Classic; users will no longer be a be able to run Classic applications.
Mac OS 10.6 eliminates support for any Macintosh with a PPC processor.
If you're not sure which Macintosh you have select About This Mac from the Apple menu. The window which appears will tell you the version of the Mac OS your system is currently running as well as the processor type and speed. Any Macintosh purchase in the past 3 1/2 years should have an Intel processor; older system will have a PPC processor.
