App Tamer 2.0.5 makes your Mac run cooler, quieter and longer Posted 3/25/2015 at 16:53 UTC in Mac by gnye@amdesign.net | Permalink | Tweet St. Clair Software today introduces an update for App Tamer, its Macintosh utility that manages applications to deliver more efficient CPU usage, increased battery life and quieter operation. App Tamer's unique AutoStop capability automatically slows down or pauses applications when you switch away from them, and then restarts them when you click back to them. This version fixes a compatibility issue with Safari and improves its user interface and usability.
