How to change the screen resolution in Mac OS X
1. Open the System Preferences (either from the Dock or from the Apple
menu).
2. Open the Displays Panel and choose the Display tab.
3. On the left of the Displays tab you can select one of the Resolutions
from the list. Higher resolutions allow you to see more “stuff”. IT is
recommending at least 1024x768 unless you have a specific reason to use a
lower resolution.
4. Quit or close the System Preferences when done.
