System Tools Apps for Mac

Apps that monitor, tweak and extend macOS itself: menu bar tools, window managers, Finder extensions and system information utilities.

What Are Mac System Tools?

System tools integrate deeply with macOS: menu bar monitors, window managers, Finder extensions, keyboard customizers and system information dashboards.

How to Choose a System Tool

Because these apps hook into the operating system, prioritize native, actively maintained software with a good track record of supporting new macOS releases.
