By default, OS X rearranges desktop spaces based on usage. If you’re like me and want to keep apps and desktops in nice tight order, here’s how to prevent that:
- Launch System Preferences
- Open Mission Control
- Uncheck: Automatically rearrange Spaces based on most recent use
I know this is an old tip, but I’ve been befuddled by this since Lion. And have just now fixed it. If you’ve just stumbled across this, let’s celebrate together not having to reset desktops every day.
