I also have this issue right now

From https://github.com/desktop/desktop/issues/13540:

When the desktop app updater window pops up asking for credentials, if it goes unnoticed, it will spin up the CPU. I stepped away from my laptop running macOS Big Sur and when I came back the fans were going nuts. Checking activity monitor showed it was using 99.9% CPU.

Got this as well on MacBook Pro 16-inch 2019 running Big Sur. Over 500% 😃

@ReagentX thanks for the extra details. I’m not quite sure what’s happening on your setup but I’ll call out some interesting things that I’ve spotted:

The CPU usage of the main app is relatively low overall (the orange chart) but the FPS chart has lots of gaps (which suggests something is awry with painting the UI):

The frames list, which breaks down how long it took to draw each frame, shows some periods where it’s above 30fps (so it’s responsive) but then has some periods where it takes 30s - 90s (yep, seconds) to paint. I can’t see anything interesting in the main process flame graphs to indicate something is stealing CPU time (for example, Git operations) but the only thing I can see is GPU activity.

@ReagentX could you try setting the GITHUB_DESKTOP_DISABLE_HARDWARE_ACCELERATION environment variable to a value like 1 and launching Desktop fresh? I had an issue a while ago where some update changed the graphics card settings on my macOS, and I wonder if you’re encountering something similar.
