St. Clair Software has updated App Tamer — its Mac utility that manages applications to yield more efficient CPU usage, increased battery life and quieter operation — to version 2.4.3.

The app’s AutoStop capability automatically slows down or pauses applications when you switch away from them, and then restarts them when you click back to them. With version 2.4.3, App Tamer can now be configured to let all processes run at full speed when the keyboard and mouse are idle (ie. you’re away from your Mac). There are also bug fixes and performance tweaks. 

App Tamer 2.4.3 requires macOS 10.8 or higher. A demo is available for download; registration is $14.95. This update is free for users who purchased App Tamer 2.x or bought App Tamer 1.x after July 1, 2013. For those that purchased a license before that date, the upgrade is $7.95.
