Information and Educational Technology and the IT Express Computing Services Help Desk are ending their support of Mac OS X v10.4 Tiger, an operating system Apple introduced nearly five years ago. Support will cease June 30, the end of the current academic year.

Tiger, supplanted by newer Apple operating systems, received its last security update from Apple in September 2009. The end of continuing security updates means 10.4 will no longer meet campus cyber-safety standards, and anyone on campus whose computers still use 10.4 should upgrade as soon as possible.

An upgrade could require a new machine. Apple's latest operating system, OS X v10.6 Snow Leopard, does not run on older PowerPC-based systems, such as G4 and G5 Macintoshes. The previous operating system, OS X v10.5 Leopard, might be hard to find for some machines; Apple no longer sells it. Read more about upgrades at the IET Macintosh page.
