A Mac window is stuck off screen.

When a window opens somewhere you cannot see, macOS is placing it at coordinates it saved earlier. Those coordinates usually belong to an external monitor you have unplugged, a display arranged differently, or a higher resolution than you are using now. The window is still open, just outside the visible area.

How do you bring an off screen window back?

• Window, Zoom. Click the app in the Dock so it is in front, then choose Window, Zoom in the menu bar. macOS resizes the window to fit the current screen.
• Window, Move to. On recent macOS the Window menu lists each connected display. Pick the one you are looking at.
• Mission Control. Press Control and the Up Arrow, then drag the window thumbnail onto a visible display or desktop.
• Change the resolution for a moment. In System Settings, Displays, switch to another resolution and back. macOS pulls stray windows into view.
• Reconnect the monitor. Plug the missing display back in, drag the window home, then unplug again with the window already on the built-in screen.

Why does macOS lose windows like this?

macOS stores window positions per app, not per monitor setup. If an app last closed on a second display and that display is gone, the app may reopen at the old spot. The same thing happens when a monitor wakes slowly or reports a different size. For related cases see restore windows after unplugging a monitor, Mac windows open on the wrong screen and windows jump to one screen after sleep.

Every window back on its own display. The 40 second demo shows a workspace saved from the SnapState menu bar and restored with one click: apps relaunch and windows go back to their saved displays, positions and sizes.

How does SnapState keep windows on screen?

SnapState is a Mac menu bar app that saves a named workspace: every window with its display, position and size, the apps to relaunch, the Space each app was on, full screen windows, and all open tabs in Safari, Chrome, Edge, Brave, Arc and Chromium. Restore it from the menu bar, with a Control-Command-1 to 6 shortcut, or automatically when a monitor connects or disconnects, on wake, or when a matching display layout appears.

Save one workspace for your desk and one for the laptop on its own. When you dock or undock, the matching layout comes back and nothing is left stranded off screen.

What are the practical details?

SnapState 2.7.5 costs $9.99 once, with a license for up to three Macs and a 14-day refund. It needs macOS 15.7 or later and runs natively on Apple Silicon and Intel. It needs Accessibility permission to move windows, and Automation permission if you want browser tabs reopened. Workspace data stays on your Mac. See SnapState.

What are the honest limits?

SnapState is not a tiling or snapping tool. It does not save browser tab groups, history or form data, Firefox is not supported, and it does not change the display arrangement, main display, menu bar or Dock. It restores app windows.
