RibbonWindow off screen on a Mac: how to get it back
Click the app so it's in front, then choose Window → Center or Window → Fill (macOS 15 Sequoia and later; Fn⌃C or Fn⌃F). On older versions, choose Window → Zoom. Each one moves the window back onto the screen in one step.
Step 1: make the app active
All of the fixes below act on the front window of the front app. Click the app's icon in the Dock or use ⌘Tab, and check its name is in bold at the top left of the menu bar. If the app has several windows, pick the lost one from the bottom of its Window menu.
Step 2: pull the window back
Try these in order:
- Window → Center (Fn⌃C, macOS 15 and later). Keeps the size and puts the window in the middle of the screen.
- Window → Fill (Fn⌃F, macOS 15 and later). Resizes the window to fill the screen. Useful when the window is bigger than the screen and the title bar is out of reach.
- Window → Zoom (any version). Resizes the window to fit, which brings it back on screen in most apps.
- Hover over the green button (macOS 15 and later) and pick a half or Fill. You need to see a corner of the window for this one.
If the app has no Window menu, or the commands are greyed out, keep going.
Step 3: the display tricks
- Change the resolution for a moment. System Settings → Displays, pick a different resolution, then switch back. macOS moves windows that are off the edge back inside the screen when the resolution changes.
- Window lost after unplugging a monitor? Plug the monitor back in, drag the window to the main screen, then unplug. Or, with the monitor connected, use the green button's Move to option to send it across.
- Window on a screen you can't see (a TV or projector that's off): turn on mirroring in System Settings → Displays for a moment so both screens show the same thing, then drag the window across.
Step 4: when it keeps happening
- The app remembers a position on a monitor you no longer use. Move the window back, quit the app with ⌘Q so it saves the new position, and reopen it.
- The display arrangement is wrong. If the monitor sits above or beside your laptop on the desk, arrange it the same way in System Settings → Displays → Arrange so windows don't end up in a corner you never look at. The external monitor guide walks through it.
Windows that are off screen on purpose
If you use a scrolling window manager, windows to the left and right of the screen aren't lost: they're columns on the strip that you scroll to. In Ribbon, ⌃⌥← / → or a three-finger swipe brings them into view, ⌃⌥1–9 jump to one by position, and the strip indicator at the bottom shows an icon for each, so you always know what's out of sight and where. That's the opposite of a lost window: everything has a place. You can scroll a strip in the live demo; pricing is $9.99 once.
FAQ
How do I move a window back onto the screen on a Mac?
Make the app active, then choose Window → Center or Window → Fill on macOS 15 and later, or Window → Zoom on older versions.
My window is bigger than the screen and I can't reach the title bar. What do I do?
Use Window → Fill (Fn⌃F) or Window → Zoom. Both resize the window to fit the screen.
Where did my window go after I unplugged my monitor?
macOS usually moves it to the remaining screen. If it doesn't, plug the monitor back in, move the window over, and unplug again, or change the resolution briefly to force windows back inside the screen.
