01. Reduce Transparency
When Transparency Settings are set to high, the graphics usage is also high. As a result, the WindowServer Process takes high CPU usage on Mac. Therefore we suggest you to reduce transparency in your Mac System to reduce the CPU usage by the WindowServer Process. Kindly follow the steps given below to reduce transparency on your Mac:
01. On your Mac Desktop, open Apple Menu.
02. Select “System Preferences” to go to that section.
03. Click on “Accessibility” icon to open Accessibility options.
04. Now select “Display” in the left side list.
05. Here you will see various options such as Invert Colors, Reduce Motion etc..
06. Find out “Reduce Transparency” option and tick the box.
07. Close the Accessibility Settings Window.
After reducing transparency, you will notice that your Mac’s Apple menu bar and Dock have become non-transparent. It also affects other apps which will ultimately reduce the WindowServer High CPU Usage on Mac.

02. Turn On/Off Automatic Graphics Switching
Many MacBook devices come with two graphics processors. The Mac System uses the suitable graphics processor as per its requirement. It also switches the graphics automatically which may cause high CPU usage by WindowServer. We request you to turn off the Automatic Graphics Switching option to check if the CPU usage gets reduced. Please follow the steps given below to turn off automatic graphics switching on Mac:
Wind Mover Mac Os Catalina
01. On your Mac, open Apple Menu.
02. Select “System Preferences” tab.
03. In System Preferences window, select “Energy Saver” icon.
04. You will see “Automatic Graphics Switching” option at the top of the Energy Saver settings window.
05. Un-check the Automatic Graphics Switching option to turn it off.
06. Close the Energy Saver settings window.
When you turn off Automatic Graphics Switching option, the Mac System will always use the high graphics processor for all apps. So you should check the WindowServer Process in Activity Monitor when Automatic Graphics Switching is turned off and turned on. If the WindowServer uses more CPU when auto graphics switching is off, you should turn it on again. You should keep the graphics switching mode which consumes less CPU usage by WindowServer.
03. Hide the Dock
On your Mac, Dock is situated at the bottom of the desktop screen. The dock contains many app icons. The WindowServer has to draw and show up those icons on your Mac display. Sometimes you don’t have any use of those icons still they are appearing on screen and using high CPU. Therefore we request you to turn on automatically hide dock option by following the steps given below:
01. On your Mac, open Apple Menu.
02. Select “System Preferences” option.
03. Find out “Dock” icon and click on it to open Dock Settings.
04. On Dock Settings Window, find out “Automatically hide and show the Dock.”
05. Check that box to turn on Auto Hide/Show the Dock feature.
06. Close the Dock Settings Window.
After the Dock is hidden from your Mac desktop, the WindowServer Process CPU Consumption will be reduced by a few percentage. You can check that change in your Mac’s Activity Monitor.
04. Disable Automatic Rearrange of Spaces
Virtual Desktop Environment is a feature provided in Mac System. If you are using Spaces, they may get rearranged by themselves. Because of this setting in Mission Control, WindowServer takes high CPU usage. You can get your CPU usage back to normal by disabling the automatic rearrange of spaces on Mac. Please follow the simple steps mentioned below:
01. On your Mac, go to Apple Menu.
02. Select “System Preferences” to open a new window.
03. Click on “Mission Control” icon to open its settings window.
04. Find out the option “Automatically rearrange spaces based on most recent use.”
05. Disable Auto Rearrange of Spaces in Mission Control Settings.
When you disable Automatically rearrange spaces option, it will make a little reduction in WindowServer Process CPU usage on Mac.
05. Turn Off Separate Spaces for Displays
Mac Computer allows the user to setup multiple displays for one system. But it can be the cause of WindowServer Process high CPU usage if each display has a separate space. Every space takes some amount of CPU and memory. As a result, WindowServer takes high CPU usage for multiple displays have separate spaces. That’s why you should turn off this feature on your Mac. Kindly follow the steps given below to turn off separate spaces for displays in Mac system:
01. On your Mac desktop, open Apple Menu.
02. Select “System Preferences” tab.
03. Find and Select “Mission Control” icon in System Preferences.

06. This setting requires log out to take effect on your Mac.
07. Log out from your Mac and Log in again.
