How to pin an app to a specific Mission Control Desktop
You can assign an app to a specific desktop in Mission Control—perfect for keeping your programs in their proper “spaces,” particularly when you’re booting up your Mac.
Before we begin, something to keep in mind: this trick applies only to apps running in standard “windowed” mode. Programs running in “full screen” automatically get assigned to their own desktops.
Are you ready to start “pinning” your apps to specific desktops? Here we go…
▪ First, navigate to the desktop where you’d like a particular program to call home. If, for example, you want Calendar to sit in Desktop 2, launch Mission Control, then click on Desktop 2 from the overhead Mission Control view (or create a second desktop if there isn’t one already).
▪ Launch the app you want to assign to the desktop—again, let’s use Calendar as our example.
▪ Go down to the Mac desktop dock at the bottom of the screen, find the icon for Calendar, and right-click it.
▪ In the menu that appears, select Options, then select “This Desktop” under the “Assign to” heading.
Now, let’s test. Go ahead and close the app you just assigned to a desktop, navigate to Desktop 1 in Mission Control, then launch the app again—and when you do, it should launch in the desktop you assigned it to.
Also, if the app you’ve pinned to a desktop opens automatically when you start up your Mac, the app will now launch in its assigned window.
OK, but what if you want to “unpin” an app from a desktop? Just right-click its icon in the dock, select Options, then select “None” under “Assign to.”
