App Tamer 2.8.4 for Mac
Mac UtilitiesApp Tamer 2.8.4, from St. Clair Software, tackles a problem every Mac owner recognises: apps you are not even looking at quietly eating processor time, spinning up the fans and draining the battery. App Tamer watches what is running, shows average CPU use for each process from its menu bar window, and automatically slows down or completely pauses background apps — then instantly wakes them when you switch back.
It ships pre-configured for common culprits including Safari, Chrome, Firefox, Spotlight, Time Machine, Photoshop, Illustrator and Word, and on Apple Silicon Macs it can push busy background work onto the efficiency cores, leaving the performance cores free for the app in front of you. App Tamer is paid software with a 15-day free trial, so you can measure the CPU and battery savings on your own machine before buying a license.
Key Features
- Automatically slows or pauses background apps and restarts them when you return

How is App Tamer different from App Nap?
macOS App Nap only works when an app's windows are hidden or fully covered, and it ignores background processes. App Tamer manages apps and behind-the-scenes processes whether their windows are visible or not.
Is App Tamer free?
No. It offers a 15-day free trial with full features, after which a paid license is required. Buy only from St. Clair Software to receive a genuine serial number and updates.
