How to rotate Mac OS X Display?

[pupuweb Blog Daily News]

You can rotate your primary Mac screen, including the built in screens
on a MacBook Pro or iMac, by accessing a hidden pull-down menu within
the Display preferences.

Here’s how to access the screen rotation option in Mac OS X:

1. Launch System Preferences
2. Hold down the Command+Option keys and click on the “Display” icon
3. On the right side of the Display preferences, look for the newly

4. Set the rotation you want, 180° flips the screen vertically
5. Close Display preferences to have the settings stay
