Mac screen zoomed in, or shifted to one side? How to fix it in seconds
It's the Zoom accessibility feature, usually turned on by accident with a keyboard shortcut or by holding Control while scrolling. Press Option-Command-8 to turn it off. If the screen looks shifted to one side and slides as you move the pointer, that's the same feature at a low zoom level, and the same shortcut fixes it.
Turn it off
- Press Option-Command-8. This switches Zoom on and off when keyboard shortcuts for Zoom are enabled.
- If nothing changes, hold Control and scroll down with two fingers on the trackpad, or with the mouse wheel.
- Still zoomed? Open System Settings, Accessibility, Zoom, and turn off "Use keyboard shortcuts to zoom", "Use scroll gesture with modifier keys to zoom" and any other zoom options that are on.
Stop it happening again
In System Settings, Accessibility, Zoom, turn off the scroll gesture if you don't use Zoom. Holding Control while scrolling is easy to do by accident, especially with a mouse.
If it isn't Zoom
- Everything is bigger, but sharp and not panning. The display resolution changed. Open System Settings, Displays, and choose the Default size.
- Only one app is zoomed. Press Command-0 in browsers and most document apps to reset that app's zoom.
- Everything is just too big. That's the resolution, not Zoom. Here's how to make the screen smaller.
- Zoomed in after plugging into a TV. Pick a resolution that matches the TV in Displays, and turn off overscan on the TV if it has that setting.
If the damage runs along one edge, CrackMac can keep windows, menus and the pointer off it. There's a free 30-minute trial.
Quick answers
How do I unzoom my Mac screen?
Press Option-Command-8 to turn Zoom off. If that doesn't work, hold Control and scroll down with two fingers, or turn Zoom off in System Settings, Accessibility, Zoom.
Why is my Mac screen shifted to the right or down?
Zoom is on at a slight level, so the screen pans as the pointer moves. Turning Zoom off puts everything back.
Was zoom a way to avoid a damaged area?

Some people zoom in to keep things off a broken part of the screen. There's a better way. CrackMac tells macOS where the working area ends, so windows, menus and the pointer stay on it at normal size.
