FAQ

PRAM is used by OS X to store certain information that the system can access quickly. Macs will store settings like which start-up drive to boot from, various display and video settings, start-up speaker volume and even the DVD’s region settings. If you feel that you need to reset your Mac’s PRAM because of the issues you’re having, do the following:

1. Turn off your Mac. Don’t worry about disconnecting the power or removing the battery.
2. Turn on your Mac and hold down the Command, Option, P, and R keys all at the same time (all four keys).
3. Keep holding down all four keys until you hear the start-up sound for a second time.
4. If you do not hear the start-up sound twice, then you most likely have not reset the PRAM.  If you find that your Mac is not retaining the information that is stored in PRAM when you perform a shutdown, then it might be time to replace your Mac’s main logic board battery.  This is sometimes referred to as the PRAM or Clock Battery.
