Apple is expected to release OS X Yosemite this Fall, possibly today after their October Media Event. Jeff Gamet of the Mac Observer has posted a handy chart detailing which Macs support OS X Yosemite and how to find out which model Mac you have.

The short answer to the question of which Macs support OS X Yosemite is pretty simple: If your Mac supports OS X Mavericks, it supports Yosemite, too.
