One of the biggest supporters of Mac gaming has been Blizzard Entertainment. In the past, the developer has released its major PC games for the Mac at the same time as their Windows counterparts, including StarCraft II, Diablo III, Hearthstone and most recently Heroes of the Storm. However, Blizzard has decided not to bring its next stand-alone game, Overwatch, to the Mac.

Overwatch was first revealed in 2014 as a team-based multiplayer shooter. While it will be released for Windows, the Xbox One and the PlayStation 4 in the spring of 2016, Overwatch game director Jeff Kaplan told Polygon there are technical reasons why the company won't release the game for the Mac:

"Currently with the technology behind Macs and the way Overwatch runs it's just too challenging for us at this point to support it," Kaplan said. "Our focus right now is entirely on PC, Xbox One and PlayStation 4."
