To zap the PRAM (Parameter RAM) on a Mac, restart your computer and immediately hold down the Command (⌘), Option, P, and R keys together. Keep holding these keys for about 20 seconds, during which your Mac may restart. Release the keys after you hear the startup sound for the second time or see the Apple logo appear and disappear for the second time. This resets the PRAM, which can help resolve various hardware-related issues.
