What is Taskglass on Mac?
By Junaid, maker of Taskglass · Last reviewed
The app you're using right now: it measures your Mac and explains what it finds.
Taskglass samples CPU, memory, energy and temperatures and keeps a small local history. TaskglassHelper is its optional, read-only helper that measures macOS's own processes. Neither sends your data anywhere.

Why is Taskglass using so much CPU or memory?
- The main window or menu bar popover is open, so Taskglass samples every second instead of every 5–10 seconds.
- The Temperature screen is open, which reads all sensors.
What to do
- 1Close the window when you don't need it; Taskglass drops to background sampling automatically.
- 2Check its own cost any time at the bottom of the sidebar.
Safe to quit? Yes.
Quitting simply stops monitoring; history already saved stays on your Mac.
Typical usage
Rough ranges on Apple Silicon Macs. Yours will vary.
- CPU
- About 0.1–0.5% in the background; 1–3% with the window open
- Memory
- 60–120 MB
