OS X introduced the Zoom feature for Mac computers. With Zoom, you can magnify your desktop and other applications, including videos. Zoom offers the ability to increase the size of your desktop to as much as 40 times its normal size, according to Apple. If you increase your screen magnification too much, or just decide you would like to return your desktop to its normal settings, you can "unzoom" -- decrease the size -- by using your keyboard, mouse or trackpad.
Place a finger on the scroll wheel of your mouse.
Scroll the wheel backward to decrease the zoom of your desktop.
Press and hold the "Option" and "Command" keys.
Press "-" -- the minus key -- while continuing to hold down "Option" and "Command."
Tap "-" until your desktop zooms out to the desired magnification.
Tips & Warnings
- Turn off the zoom function by opening System Preferences and clicking "Universal Access." Click "Off" in the Zoom section of the Seeing tab.
- If holding "CTRL" and scrolling doesn't work, open System Preferences. Click "Keyboard & Mouse." Click the "Mouse" tab. Choose "^ Control" from the drop-down box beside Zoom While Holding.
- You can also "unzoom" with a trackpad. In your System Preferences, click "Trackpad" and make sure it says "^ Control" beside Zoom While Holding. Then zoom out by swiping your fingers down the trackpad while holding "CTRL."
