If you can run the software, the question then becomes: Should you? The answer is up to you, but remember - I can't stress this enough - this is a beta. MacBook Pro from mid-2009, any MacBook Air from 2008, any Mac Mini from 2009, any Mac Pro from 2008, and (if you have one) any Xserve from 2009. Yosemite runs pretty much on any Mac that can run Mavericks - that includes any iMac from mid-2007, any MacBook from late 2008, any 15-in. Still interested in testing the software? You'll need to have Mavericks installed (which is a free upgrade you can download from Apple's App Store). If you choose to proceed, make sure to back up your data beforehand. Don't install Yosemite on computers that you rely on because, by definition, beta software is at best unreliable. "The Summer of Bugs" is what I like to call the period between WWDC and Apple's fall software and hardware releases. Expect that there will be bugs, some minor and maybe some major. Instead, I'll be looking at the major additions since last year's release of OS X 10.9 (Mavericks), and detailing how the features are implemented.īefore we start, let me be clear: Yosemite is beta. Since this isn't a final release, I haven't written a formal review, nor will I be discussing speed, stability or battery life. I installed the beta build on a 2012 Mac mini, and have been running the developer builds since their first release in June on a 2012 MacBook Pro.
