App Tamer 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 version 2.8.3

Updated on Feb 26 2024

  • Corrected issues with process control not working correctly during and after system sleep.
  • You can now create a sample report (like in Apple's Activity Monitor) using the contextual menu in App Tamer's process list.
  • vdhcoapp, the helper app for the Video DownloadHelper browser extension, is treated as a distinct application so CPU limits can be set for it separately from the web browser that hosts it.
  • Fixed the appearance of buttons in the process lists on older versions of macOS.
  • Changed several status messages so they are more informative.
  • Added support for Chromium web apps.

The app is useful for slowing down and killing apps that are consuming a lot of resources. But, the statistics it shows about the CPU is completely wrong. - Right now, Activity Monitor is showing that my CPU is 86% idle (and the other 14% is being used) while this app tells me that 100% of my cpu is being used. It, however, doesn't show which app is consuming it. The information it shows about the CPU usage is simply wrong.

App Tamer works great! Keep naughty apps from sucking up cycles for no good reason. Keep your computer running cooler, too. The program is a bit complex, but only because taming apps is a complex thing to do. There is no simple way to tame apps. Sure, you can try to prioritize apps on your own using terminal and renice, but doing that is a royal pain in the buttocks. App Tamer should be on every Mac owned by someone who wants it to last.

This is an excellent app. Unlike many of the silly mac "optimizers" this works, and works well. It's worth telling everyone about the development release that lets you move apps between performance and efficiency cores on M series macs. I've been using that for a month and it works well. Nice work by the developer. https://www.stclairsoft.com/blog/2022/01/21/app-tamer-experimentation-running-apps-on-m1-efficiency-cores/

Using an old Mac Mini to store photos, and as an audio/video server, this program is a godsend. Apple Photos can suck up CPU for no good reason, stressing my little box. This program keeps that in check. There is nothing in photos which needs to be done hurriedly. So lowering the related processes keeps things cool. There is a "Detection" setting which can alert the user to processes sucking up CPU cycles. For anything related to Photos or Spotlight, I set those processes to 10-20%. That way they still get the job done, just more slowly. Heat is the worst enemy for electronic equipment, especially computers. Anything which lowers the temperature will extend the lifespan of equipment. Whenever I hear the fan spinning loudly, I check what's going on. After weeks using App Tamer, my little box runs a whole lot happier. (And hopefully, for many more years to come.)

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

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 ?!?

Crashes when run on 10.10.5. Can't find /usr/lib/libcrypto.35.dylib

[update] turned out to be the Xcode update f-ed up the build and pulled the wrong library. Once the dev knew what was going on, he rebuilt it with the correct library and it runs fine now. All we could say after all this was
"I hate when that happens."
