How to Move a Window to Another Monitor on Mac

Moving a window to your other monitor should be one motion — and it is, once the display arrangement matches your desk. Here's the plain drag, the Mission Control route for when the window is buried, the fix for windows that hit an invisible wall, and the rescue for a window stranded on a screen that isn't there anymore.

The basic move: drag it across

Grab the window by its title bar and drag toward the other display. The pointer — and the window with it — crosses at the shared edge of the two screens. Keep going until the window sits mostly on the target display and let go. That's the whole technique, identical on macOS 13 through 15.

Details that make it smooth:

• A window straddling the boundary shows on both screens; it belongs to whichever display holds more of it when you release.
• Displays can run different scales, so a window may look bigger or smaller after the move — its point size hasn't changed, the pixels have.
• On macOS 15, a hard drag against the far edge can trigger window tiling. If the window snaps to a half you didn't ask for, press fn + Ctrl + R (Return to Previous Size) — or drop the window short of the edge.

Through Mission Control

When the window you want is buried under six others, skip the excavation:

1. Enter Mission Control (Ctrl + ↑ or a three/four-finger swipe up). With Displays have separate Spaces on — the default — each display shows its own Mission Control and Spaces bar.
2. Drag the window's thumbnail across to the other display, dropping it on that screen's desktop thumbnail in the Spaces bar.
3. Click through — the window is now on the target display and Space.

This also lets you place the window on a specific desktop of the other monitor in one motion, which a plain drag can't do.

If the pointer crosses in the wrong place

Windows refuse to cross, or cross at a weird height? The arrangement doesn't match your desk. Open System Settings → Displays → Arrange… and drag the display rectangles so the on-screen layout mirrors the physical one — left monitor on the left, tops aligned where the screens actually align. The shared edge between rectangles is exactly where windows and the pointer can cross; a mis-drawn arrangement is the invisible wall.

Rescue a window stuck off-screen

Unplugged a monitor and lost a window with it? Usually macOS pulls orphaned windows back — but when one stays lost:

1. Click the app in the Dock so it's frontmost, and pick the missing window from the bottom of its Window menu.
2. Choose Window → Zoom. Zooming re-fits the window inside the visible screen.
3. On macOS 15, fn + Ctrl + F (Fill) does the same job even faster.
4. Still hiding? Reopen Displays → Arrange and jiggle the layout — re-arranging forces macOS to re-place every window inside a real screen.

Full-screen windows move too

A full-screen app occupies its own Space, so a title-bar drag isn't available. Two clean options: take the app out of full screen with the green button, drag the window across, and go full screen again on the target display — that display now owns the Space. Or stay in Mission Control and drag the full-screen app's thumbnail from one display's Spaces bar to the other's; with separate Spaces on, the whole full-screen Space migrates in one motion.

Make apps open there in the first place

Moving windows by hand gets old if the same app always starts on the wrong screen — teach it a home with the wrong-display fix.
