I have seen these two questions
and I have the same problem with
WindowServer on both a Macbook Pro 16" and an Macbook Air 2020, but I also have problems with
According to the script here https://apple.stackexchange.com/a/393207/31395 my Air's total awake time since last restart is 1 day, 22:07:19.374478 (
9 days, 13:59, 5 users, load averages: 5,04 5,11 4,79).
Looking in Activity Monitor, WindowServer has used 42h05m since last restart (since the awake time is 46 hours, that is over 90 % on average) while kernel_task 14h19m ≈ 31 % (I will update this question with corresponding number for my MBP later on).
I mostly use this machine for web browsing and office tasks. These numbers are completely unreasonable! The computer is updated and reasonably "clean". Since I have the same problem on my other machine I don't think it is anything specific to this setup.
The only slightly odd usage is that I use Firefox - a well known resource hog - and it is hard to test if Firefox is the culprit since I need to use it 80-90 % of the time. A different browser isn't really an option.
Any ideas what might be going on here?
