About this guide

If you use several desktops, called Spaces, macOS reorders them so that the ones used most recently are quicker to reach. That means Desktop 2 is not always where you left it. One switch keeps the order fixed.

The screenshots show System Settings on macOS Tahoe 26.

Good to know

Group windows by application, in the same group, organises the windows by app in Mission Control when several apps have windows open.

In short: Apple menu > System Settings > Desktop & Dock > Mission Control > Automatically rearrange Spaces based on most recent use off.
