App Tamer

January 10, 2018

App Tamer 2.3.4 adds an option to quit idle apps and controls the CPU usage of complex applications more accurately.

This version is a free update for App Tamer 2 users. Please note that if you still have App Tamer 1.x, this is a $7.95 paid upgrade if you purchased version 1.x before July 1, 2013.

What's new in App Tamer 2.3.4

  • App Tamer can now be set to quit applications after they've been idle in the background for a certain amount of time. Note that if the application pops up alerts about unsaved changes, etc, those alerts will still pop up. App Tamer doesn't auto-OK them or otherwise intervene.
  • There were situations in which App Tamer's management of CPU usage could fail for apps that have multiple sub-processes, like web browsers and Spotlight. This issue has been fixed, so managed apps should stick more closely to the CPU usage you've set for them.
  • When you turn on Time Machine Acceleration, App Tamer checks to see if Time Machine is also configured to be slowed to a particular CPU limit and will put up an alert to let you know that these settings are at cross purposes.
  • App Tamer's own CPU usage has been reduced.

What a beautifully simple yet revolutionary App! But don't tell Apple that I can put off upgrading my Macbooks for another year ;)

It's "just working". Thank you so much. Love the product. Love the support.

A) the user interface is completely intuitive, B) it seems to work perfectly and instantaneously, and C) I did independent confirmation with my usual tool (top from the command line) and astonishingly, Safari was sitting there firmly fixed at 0 %CPU. That is awesome!!! I am absolutely going to be telling everyone I know to go buy this immediately!
