However, on most Macs, the number of CPU cycles WindowServer consumes should be so small you don’t notice it. When you consider that windows in macOS have lots of effects, such as transparency and drop shadows, it’s hardly surprising that drawing and redrawing them on screen consumes resources. Every time you move a window around, edit an image in Photoshop, or switch to a different tab in Safari, WindowServer needs to redraw your screen. Most graphical elements are refreshed regularly, which is why WindowServer needs those CPU cycles. The more windows you have open at any one time, the more CPU cycles WindowServer needs. Simply, it’s the macOS process that draws elements on the screen, whether they are application windows, icons, or websites. Most of the time, you won’t have to think about it or even know it exists, but if it starts using lots of CPU cycles, it may slow down your Mac. That relationship is managed by WindowServer on your Mac - a process that is responsible for drawing graphical elements on display.
