It’s also possible that the windowserver process is using lots of CPU power even when you don’t have any resource-intensive programs open on your Mac. On the other hand, if you are uncertain about the program’s trustworthiness, it may simply be best to uninstall it. If, for instance, you’ve noticed that a certain app that shouldn’t be too resource-intensive is causing an unusual increase in CPU usage, then, if you know that the app is legitimate, you can contact its developer and let them know about the potential issue they may need to fix. In some cases, however, it’s possible that the high use of CPU that’s coming from windowserver is triggered by a bug in a program that you are running. Obviously, if you need to use the visually-intensive software that’s triggering the increased CPU usage, you’d need to put up with the potentially decreased performance of your Mac.

In such cases, if you want to decrease the CPU that’s being used, you’d need to close those programs. High CPU usage caused by this process is especially likely if you are running any visually-intensive software, such as video-editing apps or video games. For this reason, it wouldn’t be surprising if windowserver starts using up significant amounts of CPU in order to function. Basically, the windowserver process is responsible for the visualization of every app that you open and use on the computer. Windowserver is an important macOS process that’s constantly running and is responsible for the communication between the apps that are running on your Mac and Mac’s display. It’s common for Windowserver on Mac to consume lots of CPU power when the user is running games or video-editing software. I advise following this bug report and keeping track of when they resolve this so you can turn autoupdates back on afterwards.Windowserver on Mac causes high CPU usage when resource-intensive programs that constantly change what’s happening on the screen are running on the Mac. You should now be extra sure to check for an perform updates manually on a regular basis to keep your system secure.
