How to reset the PRAM (or NVRAM) on your Mac

On a recent chat with Apple support, the representative suggested I reset my PRAM. From what I understand this will clear BIOS like values that may cause a Mac to malfunction. It only takes a second to do – here’s how:

Press CMD+OPTION+P+R, then start the system. You’ll need three hands or a portable keyboard to do it.

Hold those four keys down until you hear a second startup chime (or if you’ve previously disabled in, until you hear one chime).

That’s it!

Note that there are technical differences between the PRAM, NVRAM and the SMC, but I really don’t know what they are. You can reset them all to make your Mac behave if it’s doing weird things though.
