How To Reset a Mac’s NVRAM/PRAM – Guide

Assuming your Mac is acting unusually and a software update hasn’t fixed the problem, it’s probably an ideal opportunity to reset your Mac’s PRAM, SMC, or potentially NVRAM.

Rebooting these systems is an invaluable piece of solving the Mac problem. guide, I’ll cover when, why and how to reset your PRAM, SMC and NVRAM on your Mac PC or MacBook.

  • You may have heard about random access memory, commonly called RAM. Memory should not be confused with computer storage (hard disk space), as RAM consists of chips in the computer that store active applications and processes.
  • This means that when you open an application, you are telling the computer to load it from the hard drive into RAM. Once the application is closed, it exits RAM and releases up memory for other applications.
  • RAM can also be used to remember system settings. Do you know how the computer remembers what time it is, screen brightness, or system volume? This is PRAM; the system information your computer stores; even when turned off.
  • PRAM is short for Parameter Random Access Memory and includes information about the designated boot disk, screen resolution, speaker volume, and other information.
  • Unlike other types of RAM, PRAM is not reset when the computer is turned off. This is because a small battery is installed, which retains data when the computer is not turned on.
  • NVRAM is the updated Mac terminology for PRAM and is short for non-volatile RAM. Since NVRAM is non-volatile, settings do not change when the computer is turned off or disconnected from power. When it comes to troubleshooting, resetting NVRAM or PRAM on a Mac is the same thing.
  • In PCs, motherboards have a similar component called CMOS. CMOS RAM also uses a small battery or power supply to store BIOS information while the computer is off. PC users can learn how to manage your BIOS settings by visiting the motherboard manufacturer’s website.
