Another feature that impresses me is that it is able to airplay MKV video movie from Mac to Mac, from Mac to Apple TV. This means that you can watch MKV on Mac even on airplay supported TV with no limits.
Method 3: QuickTime Plugin Perian
Mac Quicktime MKV plugin - Perian also has a solution to the problem How to play MKV on Macbook, iMac or Mac mini. With Perian, you can play MKV video movie in HD, SD on any Mac OS X 10.6.8 or later, El Capitan, Yosemite, needless of MKV player for Mac.
