Resetting the Parameter RAM (PRAM)

< Previous | Next >

For Mac OS X computers, resetting the PRAM may correct a variety of problems by returning various settings back to the default, such as display and video settings, time zone, start-up volume choice, speaker volume, and recent kernel panic information, if any.

To reset the PRAM, hold down the [Option], [Apple], [P], and [R] keys at the same time while the computer starts up. Continue holding down the four keys until your computer chimes a second time, then let go. Your computer should start up properly.

If the problem(s) persists, contact the Computing Help Desk at 646-2999 and select from the options provided, send electronic mail to help@dartmouth.edu, or call your department's computing support office.
