history
Project history and usage
App Tamer is a commercial macOS process-management utility that automatically pauses or throttles background applications to reduce CPU use, heat, fan noise, and battery drain.
Project history
St. Clair Software developed App Tamer as a commercial Mac utility for automatically reducing background CPU use. Version 2 introduced the product generation represented by the current manual, and the vendor is publicly testing a major version 3 update.
Adoption history
App Tamer has been maintained across both Intel and Apple Silicon generations of macOS. The current 2.x line supports modern systems, while an older 2.7.6 build remains available for macOS 10.9–10.12.
How it is used
Users inspect processes from App Tamer's menu-bar window, then configure selected applications to stop in the background, run on efficiency cores, or stay within a CPU limit. Built-in policies cover common browsers, Adobe applications, Spotlight, and Time Machine.
Why package nerds care
App Tamer turns low-level process controls—pausing tasks, limiting CPU consumption, changing priority, and favoring efficiency cores—into per-application automation. It is notable to Mac utility users as a graphical, policy-driven complement to tools such as nice, Activity Monitor, and manual process suspension.
Timeline
- Before July 2013: App Tamer 1 licenses were already being sold.
- 2013: Purchases from July onward qualified for a free upgrade to version 2.
- Apple Silicon era: App Tamer added efficiency-core controls.
- 2026: St. Clair Software publicly tested App Tamer 3 betas.
Related projects
- App Tamer complements macOS Activity Monitor and command-line process-priority tools. It is produced by St. Clair Software, also known for Default Folder X.
