Apple Raises Leopard System Requirements

Susan Hall

The Inquirer cleverly uses a headline "Performance Too Spotty" on news that just weeks before launch, Apple has decided its Leopard operating system doesn't work well on G4 processors and has boosted the minimum system requirement to a G5. Leopard is due for release in October.


AppleInsider reports that Leopard ran too slowly on 800MHz PowerPC G4 systems, so Apple has been telling testers the OS can't be installed on those systems.


That means there will be no OS upgrade for the 800MHz systems PowerBook G4, PowerMac G4, iMac G4, iBook G4, and eMac.

Glad you included a link to AppleInsider, which has proven itself to be a very reliable source of late. Their article states more clearly (and with less dependence on witticism) that "an Intel processor or a PowerPC G4 (867 MHz or faster) or G5 processor" will be capable of running Leopard. This draws the line at portable models like some of the iBook G4 versions, introduced in October 2003, which included G4 processors operating at 800, 900, and 1,000 MHz, and at desktop models like the some of the Quicksilver G4s introduced in January, 2002. Apple's support for discontinued models appears to typically run about 5 years; this performance spec, it would appear, supports models on the edge of that time frame. Reply
