OS X Mavericks: Make the screen image larger using an Apple mouse
If you use an Apple mouse, you can use it to zoom in on part of your screen. Use Mouse preferences to set zoom options.
Some portable computers also support making the screen image larger.
- Choose Apple menu > System Preferences, click Accessibility, then click Zoom.
- Select “Use scroll gesture with modifier keys to zoom” to turn on zooming, and enter a modifier key or keys to turn zooming on or off. (To use multiple modifier keys, press them at the same time.)
If you’re using an Apple Magic Mouse, see this help topic:
- Set additional zoom options.
Select “Smooth images” to make the zoomed screen images appear smooth.
Select “Zoom follows keyboard focus” to make the zoomed image shift to follow your cursor.
Select Fullscreen or Picture-in-picture from the Zoom Style pop-up menu.
When zoom is turned on, hold down the modifier key or keys and use the scroll ball to enlarge or reduce the screen image.
