App Tamer2.5.1

19 May 2020

Efficiently manage your CPU cycles, save energy, and more.

Overview

App Tamer tames your processor-monopolizing apps and keeps them from chewing up excessive CPU time and battery life. Powered by a unique AutoStop feature, App Tamer stops each application when you switch away from it - when you return to that app, it restarts automatically.

App Tamer is built around an attractive and clear user interface, designed for managing all your running applications with minimum distraction or frustration. With helpful displays, you can monitor the average percentage of your processor(s) being used by each app, or access a graphical history or your CPU usage. Easily enable AutoStop for any application, or limit it to a certain amount of CPU time.

Don't waste time trying to manage CPU usage on an app-by-app basis - liberate your Mac with App Tamer.

What's new in App Tamer

Version 2.5.1:
  • There is now a "manage" AppleScript command so you can change settings for an app using AppleScript.
  • App Tamer won't put up "using too much CPU" notifications for processes that it's already managing.
  • When App Tamer shows a notification about an app using too much CPU, clicking on the "Let it continue" button will silence warnings for the next 10 minutes. This length of time can be controlled from Terminal using "defaults write com.stclairsoft.AppTamer notificationMuteTime XXX" where XXX is the number of seconds to silence notifications.
  • Processes that are hidden by App Tamer's "Hide when idle" setting will no longer be automatically un-hidden if they were throttled or stopped and are returned to normal CPU usage.
  • App Tamer's window pops down from its menu bar icon correctly in full-screen mode even when App Tamer's icon is set to show in the Dock.
  • Setting the statistics update interval to "never" will no longer disable App Tamer's tracking of application idle time for the "Quit when idle" and "Hide when idle" features.
  • App Tamer will now correctly slow and stop web browsers that are being run with their ownership set to a different user.
  • Fixed problems with Command-Q being enabled even when App Tamer wasn't showing its icon in the Dock.
  • Processes that are run via 'sudo' or 'su' from the Terminal are now shown correctly in the process list.

New version, old love – since years ! App Tamer is one of my "must have" apps – whenever I see CPU spikes by other apps over a longer time, App Tamer is THE quick solution. Killer app!

Overall a very good app. But one issue: AppTamer interrupts Chrome when streaming music even if I tell AppTamer not to stop or slow down Chrome. Why? Same with Skype. So I can only stream music or skype when I stop AppTamer?

Simple to operate. Intuitive. Enables you to control how much and for how long an app can control your CPU. This is valuable when you are working on several projects at the same time so that it is far less likely that your Mac gets overwhelmed. Works perfectly under Mojave.

It's a good app, but the way it throttles browsers even when youre streaming music is asinine. How it doesn't automatically detect this is beyond me

Awesome update of App Tamer version 2.4 – if every developer would work like St. Clair Software Mac software could be such a pleasure. Thank you very much for these ongoing improvements of an already outstanding Mac software !

Update: The developer didn't release a fixed version about the critical bug which I mentioned before (in this app, I don't manage anything, but a lot of processes related to Today Widget are be managed). Poor Developer.

I really HATE this developer's Attitude. I found a critical bug (in this app, I don't manage anything, but a lot of processes related to Today Widget are be managed), and the developer admitted it's a bug, and he's fixed it, but he don't want to release an Alpha version, and it PASSED ALMOST 4 MONTHS after he fixed it. The following is his reason; you guys can judge it by yourself. Please note that it PASSED ALMOST 4 MONTHS after he fixed it. --- Releasing a new version requires significant testing to make sure everything in the product works as it should, and being a one-person business, that significantly affects the amount of development work I can get done. So I can't make new releases every time I make a change. --- It PASSED ALMOST 4 MONTHS after he fixed it. It's So Funny. Please judge it by yourself.

AppTamer is not able to slow down spotlight engine, spotlight indexer and hooker on 10.13.4. Makes the app pretty much useless I guess ?!?
