Apple's new desktop operating system – OS X 10.10 Yosemite – is out, and Mac users are asking the obvious question: Will my Mac run Yosemite?
I've dug around in the published specs for and drawn up a list of hardware that will run OS X 10.10 Yosemite.
Before you do that, you need to know what Mac you are running. To do find out, click on the Apple then select About This Mac and then click on More Info…. This will bring up a dialog box that tells you what hardware you are running.
With that out of the way, here's a listing of the oldest Apple hardware capable of running OS X 10.10 Yosemite.
This, incidentally, is the same list of hardware that can run OS X 10.9 Mavericks.
So, if you have the above hardware or newer (in any configuration, it doesn't matter if you did or didn't buy extra RAM or disk space or the better CPU) then you are good to go with Yosemite.
