My WindowServer usage was over 90% before but it went back down to under 10% after I did what he said. I also only needed it to test one site I was developing. I had the exact same things he did: MBP slow even when nothing is running, WindowServer always running high. So I think I can vouch for it being true. It seems to have worked for me also.

EDIT: Maybe it's just placebo. I checked the CPU usage on WindowServer before and after deleting & restarting.

If you’re having visible performance problems, file a report with Feedback Assistant. It’s ok if it seems to be a 3rd party app causing the issue.

(High CPU use isn’t necessarily a real performance issue and might be caused by just having Activity Monitor open.)

Apple does not support or fix third party apps.

This is 100% chrome, with their annoying updating agent, which you can't remove

You're awfully confident for someone who has provided no additional evidence.

The OP claims the high CPU usage went after uninstalling chrome and rebooting their machine.

Rebooting their machine.

The thing we tell everyone to as the absolute first step in trying to solve any problem with a computer, "have you tried turning it off and on again?".

This isn't proof that chrome or keystone or anything at all caused the problem. We have nothing to determine the root cause.

I've had numerous problems with keyagent. It was horrible. I spend way too much time on trying to get that monster to work normally or get it removed.

But it's an "essential part" of chrome

Apple likes it when the products they sell work properly and would like to hear about it when common third party products are causing that to not happen.

Yeah, next time I'll try that as well! Completely forgot Feedback Assistant existed, but I'm glad it is back to normal speeds now.

After reading your post I did the same thing. Similar results 90% to 20% in my case. Anecdotes aren't data but I am glad I tried.

Yeah, I had my friend try it as well because he said his was suggish as well. He said he had a similar experience
