What is WindowServer on Mac and How to Fix WindowServer High CPU

WindowServer draws the graphic elements on your screen every time a new window, app, or anything needs to change on the screen. If there are issues with WindowServer, it consumes a lot of CPU resources to reflect the changes on the screen. Here is the quick navigation of fixes to reduce the usage of CPU resources by WindowServer.

With time, the virtue of every electronic device is to slow down since it needs more resources to support the robust applications developed over time that use extensive resources. But if a brand new laptop's performance gets slow, we need to investigate it. This happens when a process called Mac WindowServer uses up most of the CPU resources resulting in the slowdown of the OS. In this article, we will learnwhat WindowServer is on Mac,为什么它会消耗许多资源,如何to fix this issue. Continue reading to know the details.

What is WindowServer on Mac?

The most important part of your Mac is your screen and the apps it displays on it. The Program or Software responsible for maintaining the relationship between the Screen pixels and the apps is WindowServer. The program is a collection of services grouped to manage the application windows on your Mac. You will never bother to learn about this and should know when it slows down the PC.

The function of WindowServer is to reflect the graphics of the applications on your Mac's screen. Whether you are using an app, playing a game, surfing the internet, or doing anything that requires you to open a window, it is managed by the WindowServer.

Though macOS largely support the program, it does not mean the software runs seamlessly at all times. This is where your problem comes in, theWindowServer high CPU on Mac. In the next section, let us understand why the WindowServer uses a lot of CPU cycles on the Mac and why it slows down the whole System.

Why the WindowServer process eats up a high CPU

必须定期refre屏幕上的图形shed to present the visual changes effectively on the net. Every time you move a window, edit a photo, write something, or even scroll down on your screen, the windows get refreshed, and the WindowServers redraw or present all these using CPU resources.

Along with these, connecting external monitors, improper implementation of transparency effects, clogged up files and folders, unused applications on the desktop, and additional desktops may contribute to this CPU usage.

Why You Should Reduce Mac WindowServer CPU Usage

Now that you know what WindowServer on mac is and why it uses a lot of resources let us understand why and how we can tackle the High CPU resource usage if we get into the details of how windows and desktops consume a lot of CPU cycles. Please take a look at these details to know more about it.

• Faulty or Out of date Apps:Due to inaccurate or out-of-date apps, the WindowServer has to frame the screen every few seconds due to the hogging memory.
• Multiple Displays:Multiple displays use more resources for an app and up the computer's memory.
• Messy Desktop:If you have multiple apps on your desktop, every icon or pixel change must be redrawn to reflect it, resulting in a cluttered desktop.
• Modern Graphics:For games and apps with high graphics, it is generally hard for any computer OS to keep up, so the old systems with new OS struggle with modern pictures.

Checking if the Windowserver Is Using Excessive CPU or Not

We can track the macOS utility of CPU usage on the Activity Monitor. This feature monitors the macOS usage of memory, disk, CPU, network, and energy.

How to Launch the Activity Monitor:

Step 1.Open the "Applications" and Navigate to the "Utilities" section.

Step 2.Launch the "Activity Monitor".

Step 3.Click on "CPU" to know the CPU usage.

If the WindowServer is on top and uses almost 60% of the CPU cycles, it is a problem you must address.

6 Ways: How to Fix WindowServer High CPU Usage on Mac

We have curated a list of solutions to reduce the high CPU usage on Mac. These are not one-fix-at-a-time solutions, and all the fixes aim to minimize the WindowServer work on your screen to reduce CPU usage. Try to follow as many as possible.

1. 1. Accumulate Files and Folders
2. 2. Close Unwanted Apps and Windows
3. 3. Turn off the Transparent
4. 4. Disable Rearranging of Spaces
5. 5. Update the Apps and the macOS
6. 6. Reboot your Mac

Solution 1. Accumulate Files and Folders on Your Desktop in One Place

If you have many folders, files, and applications on your desktop, for WindowServer to keep up with them takes a lot of memory and CPU cycles. Try accumulating or reducing the number of files and folders on your screen.

For example, if you have 30 files and 10 folders on your desktop, try to put them in one folder. This makes it easy for the WindowServer to visualize one folder instead of 40 on your desktop.

Solution 2. Close Unwanted Apps and Windows

If many apps and windows are opened at a time and run in the background, they will consume more CPU resources. Irrespective of the Mac you are using, the WindowServer has to allocate theCPU cyclesfor these unnecessary apps and Windows, even for the browser tabs. So, to reduce resource consumption, close the unwanted tabs and windows.

Alternatively, if any applications run in the background longer, especially high-resource applications like games, it is essential to quit them. We can do this by using Force to stop the applications.

ToForce Quit, PressCommand + Option + Escapeto open the applications list, select the apps you want to quit, and Click "Force Quit" at the bottom of the Window.

Solution 3. Turn off the Transparent Effects of macOS

Transparent effects consume a lot of CPU resources to give out better visual effects, but in turn, they use moreRAMand CPU and slow down the Mac. We can reduce the transparency effects on our Mac to speed up the OS processing to boost our machine.

Steps to reduce transparency on Mac:

Step 1.Open the "Apple Menu" and Select "系统设置".

Step 2.Navigate to the "Accessibility" section and open the "Display Option".

Step 3.Enable the "Reduce Transparency" box.

This is useful to run your Mac even faster, even if you are not facing any slowdown issues.

Solution 4. Disable Automatically Rearranging of Spaces Based on the Recent Use

If you have Spaces enabled on your Mac (Virtual Desktop Environment on macOS), it will make a massive difference for WindowServer if you disable their automatic rearranging. If this option is disabled, we must manually arrange the Spaces for further use.

Steps to disable Spaces Rearrangement:

Step 1.Open the "Apple Menu" and Select "System Preferences".

Step 2.Navigate to "Mission Control"and Disable the "Automatically rearrange Spaces based on the most recent use" setting.

If the spaces are arranging themselves automatically, the WindowServer has to allocate more CPU cycles to present them. However, this might seem small, but it reduces the CPU consumption for WindowServer.

Turn Off Spaces for Multiple Displays:

If you are using multiple display setups on your Mac, you can turn off Spaces for each display to lower the WindowServer CPU usage on your Mac. You will find the option in the Mission Control screen itself. Uncheck the "Displays have Separate Spaces."

Solution 5. Update the Apps and the macOS

Applications that are out of date cause may also use high CPU, so make sure all your applications are up to date, and yourmacOS is updated.

Launch the "App Store" app, and check for the updates for apps downloaded from it. For other apps, either download updates from the app or go to the website to check for updates and install them.

To update the macOS:

Step 1.Go to the "Apple menu" and navigate to the About this Mac section.

Step 2.Click on a software update to see if any updates are available to download.

Step 3.Download the available updates.

Solution 6. Reboot your Mac

We often try to keep our Mac in sleep mode to resume work after some time. But you must restart your Mac once in a while to free up RAM and remove the system cache and temporary files.

A simple reboot will give the OS a fresh start and fix minor glitches in the software. Sometimes, it can improve the high CPU usage by WindowServer issues also.
