As of June 2015, the Android emulator BlueStacks is not officially available for Macintosh computers, and a release date has not been set. However, an older version that was previously available may still be found on some websites
The BlueStacks development team lists a Macintosh version as "coming soon" on their website, but no other details are available. Builds of a Macintosh version were available in 2013 and 2014, and these older versions are still available from some third-party sites. The development team is currently focusing heavily on the Windows version of the emulator. It may be possible for high-end Macintosh computers to run the Windows version of BlueStacks with the Wine emulator.
