You can use multiple virtual desktops, called Spaces, on macOS 27 just as on previous major versions.


How to Create and Manage Desktops

  • Open Mission Control: Swipe up with three or four fingers on your trackpad, or press Control + Up Arrow (or the F3 key on some keyboards).
  • Add a Desktop: Move your cursor to the top edge of the screen inside Mission Control to reveal the Spaces bar, then click the + (plus) button on the right. 



  • Switch Desktops: Swipe left or right with three or four fingers on your trackpad, or press Control + Left/Right Arrow.
  • Move Apps Between Desktops: Open Mission Control, then drag an app window up and drop it onto the desired desktop thumbnail in the top bar. 
  • Close a Desktop: Open Mission Control, hover over the desktop you want to remove in the top bar, and click the X icon in its corner

If that is not working as expected, there are some standard troubleshooting steps to follow. Have you rebooted your Mac? If not, that's the first step. If that does not help, then see if the problem is present when you boot in safe mode. That process performs some system cleanup and clears caches, and also disables 3rd party extensions that may cause problems.

If that does not correct the issue, test in a new user account. A newly-created user account will have all settings at default, and if the issue does not occur in that new account then it provides guidance on what may need to be changed to correct the issue.

Once the testing is complete, the new account can easily be deleted.

Those steps will help to isolate the problem.

More than what exactly?

How many desktops do you have added currenlty?

What happens when you try to add another desktop?

Do you get an error? If so, what does it say?
