Standalone Updates let you update to a newer version of Mac OS X from your hard drive instead of using Software Update, which requires an Internet connection. Tiger is immune to the “goto fail” bug discovered in early 2014. The following Macs were supported in OS X 10.3 but not 10.4: beige Power Mac G3, tray-loading iMacs (which can run it via an unsupported installation), and the Lombard PowerBook G3 (which can also run it via an unsupported installation). See Installing OS X 10.4 Tiger on DVD-Challenged Macs Using FireWire Target Disk Mode and Using FireWire Target Disk Mode to Install OS X on Macs without DVD Drives for details. It is possible to install Tiger on Macs without DVD-compatible optical drives. The PowerPC and Intel versions of Tiger were maintained in parallel, and you can’t boot a Mac from a version of Tiger made for the other hardware architecture. Tiger would become the first version of OS X to support Intel Macs when they began to ship in January 2006. We strongly recommend more than 256 MB of memory – at least 512 MB if your Mac supports it. Many consider Tiger a high point because of the wide range of hardware it supports and its length of time on the market, which we will probably never see matched with Apple moving toward an annual update cycle.Īpple’s official hardware requirements for Tiger are a G3 CPU, 256 MB of system memory, 3 GB of available hard drive space, an optical drive that supports DVDs, and a built-in FireWire port, although it can be run on the 350 MHz iMac, which does not have FireWire. Mac OS X 10.4 Tiger was released on April 29, 2005, went through 12 revisions, and wasn’t replaced until OS X 10.5 Leopard arrived on Octo– two-and-a-half years later (almost 30 months to the day).
