How do I correctly set strictly only one desktop? With Desktops, you can have more than one Desktop.

I want to assign absolutely only one Desktop, not two.

How do I do this exactly?



When I click F3, it looks like this:



(Does that mean I have only one?)



Resolved!

Buscar웃 has identified the issue.  I manually deleted the 400 desktops and now this issue:

Absolutely eliminate &quot;Automatic new Desktop when dragging&quot;

is finally resolved.
That is amazing.

You have created so many desktops that macOS can only display them as a dot.

That line of dots represents your desktops. I did not count but it must be more than 50.

How to delete them.

Press F3

Hold Option Key and keep clicking on the X showing to delete them.
