Krisp High Memory and CPU Usage on Mac

Ongoing macOS Updated October 21, 2026

Quick answer

Users report Krisp using ~1.4 GB of RAM even on standby and heavy load during Teams screen sharing. Turn off the note taker if you don't need it, use the Balanced mode, and quit Krisp between calls.

Most likely fix: Confirm Krisp is the culprit.

Symptoms

Mac slows down, fans spin up or audio gets choppy during calls; Activity Monitor shows Krisp near the top of Memory or CPU.

Why it happens
