APPLE MAC G5 1.6 RELEASED PRICE MAC
Reliability ratings are based on statistics compiled by MacInTouch in June 2006, at which time the dual-core Power Mac G5 models had only been on the market for 8 months. Unfortunately, reliability has been all over the board, with up to one-third of some versions requiring service in the first few years of use. Leopard (the first version of OS X with no support for Classic Mode) is supported on all G5 Macs. Still, SATA drives are inexpensive, so a Power Mac G5 can make an inexpensive Time Machine backup server. Bear in mind that Apple’s partion mapping system can only support drives with up to 2 TB capacity – about half as much as today’s biggest hard drives. When running OS X 10.5 Leopard with Personal File Sharing enabled, you can use a Power Mac for Time Machine backups on your network. Although all G5 Power Macs use 150 Mbps SATA for their hard drives, they use the older Ultra ATA/100 for their optical drives. With the final generation, Apple moved to dual-core CPUs and PCIe, the same expansion bus found in Mac Pros prior to the 2013 model. Prior to the last generation, Apple used the same PCI slots found in previous Power Macs in the entry-level model and the newer, faster PCI-X slot in the two faster versions of each generation both PCI and PCI-X lines used 8x AGP for video cards.
There were the first Power Macs with built-in USB 2.0 and the first to use SATA. The Power Mac G5 line included the most powerful PowerPC-based computer Apple ever sold, also making it a powerful line for Classic Mode – especially the last generation dual- and quad-core models, as Classic then has unfettered access to one of the Power Mac’s cores.
