How To Un-Zoom Mac Screen

It sounds like you accidentally triggered the screen zoom feature on your Mac. Here's how you can un-zoom it:

Method 1: Using the Keyboard Shortcut
Press Command + Option + - (minus key) to zoom out.
You can also try Command + Option + 8 to toggle the zoom feature on or off (if the zoom function is enabled in settings).
Method 2: Using System Preferences
If you’re still zoomed in, you can turn off the zoom feature in the settings:

Go to Apple Menu > System Preferences.
Click on Accessibility.
Select Zoom from the left sidebar.
Uncheck the box next to "Use keyboard shortcuts to zoom" or "Use scroll gesture with modifier keys to zoom", depending on what you’re using.
