OS X Yosemite promises to make it easier to share information with your iPhone, iPad and iPod touch, can send and receive calls through your iPhone, more powerful Spotlight searches, iCloud Drive support, a redesigned interface that takes visual cues from iOS 7 and iOS 8, and more.
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. That said, sometimes a chart helps, too.

Apple has been pushing out updated versions of what it hopes will be the shipping version of OS X Yosemite to beta testers, and Thursday's media event would be a perfect time to announce an official release date. Yosemite will be a free update through Apple's Mac App Store.
