It's hard to believe that the Macintosh is 30 years old. To learn more about the venerable line of computers, you must make room on your iPhone, iPad or Mac for the Mactracker app from Ian Page. Mactracker is THE reference guide for the Mac, providing specifications and support details for every Apple Macintosh computer ever made.
We've covered Mactracker over the past decade as it evolved from a Mac to an iPhone and then an iPad app, but on the anniversary of the Macintosh, it's worth taking another look. The tracker continues to be updated with new model information and updated support statuses for now obsolete models. It also tracks OS X and iOS versions as well as peripherals like Apple mice, keyboards and more. If it has an Apple label on it, it's likely in the Mactracker database.
While the iOS version is a handy pocket reference, the OS X version of Mactracker has a few extra goodies like a "My Models" list that stores the models you own and tracks their warranty status. There's also a compare feature that allows you to compare the specifications or the differences between several Mac models at the same time.
