How do I control where apps open on Mac desktop spaces?

Create spaces: Use Mission Control to add multiple desktop spaces
All desktops: Right-click app in Dock > Options > All Desktops
Specific desktop: Go to desired space, right-click app > Options > This Desktop
Remove assignment: Right-click app > Options > None

🍎 Set Up Multiple Desktop Spaces on Mac

When using Luna Display, some apps may open on the wrong screen. You can manage where apps open by setting up Multiple Desktop Spaces on your Mac.

⚠️ Note: Since macOS Ventura 13.3.1, this feature may no longer work as expected. Results may vary.

With Luna running, open the Apple Menu in the top left and select System Preferences
Open Mission Control, or swipe up with 4 fingers on your trackpad
At the top of your screen, click the + button in the upper right to add more desktops
To switch between spaces, swipe up with 4 fingers or open Mission Control and choose the desktop you want to use

You can set apps to open on all desktops, one desktop, or no desktop.

Find the app in the Dock that you want to stop from opening on a specific desktop
Right-click the app and go to Options
Select None - the app will no longer be tied to a specific desktop space

Will this work on all macOS versions?

❌ Not reliably. Since macOS Ventura 13.3.1, this feature may not work as expected.

✅ Alternative: Try manually dragging app windows between spaces or using Luna Display's built-in display management.

❗Results vary: Desktop space assignment behavior depends on your specific macOS version and system configuration.
