Guide: How To Reset a Mac’s NVRAM/PRAM
Assuming that your Mac is running arbitrarily and the software update has not fixed the issue, there is a perfect possibility to restart your Mac PRAM, SMC, or powerful NVRAM.
Special cases may include any of the following: fans running arbitrarily, Wi-Fi networks not showing up, mounted drives are missing, screen is not changing, Bluetooth is not working, MacBook is not charging as far as possible – or a variety of different issues.
Resetting these systems is an invaluable part of troubleshooting your Mac. In this guide, I will cover when, why, and how to restart your PRAM, SMC, and NVRAM on your Mac or MacBook PC.
What is PRAM?
- You may have heard of Random Access Memory, which is commonly referred to as RAM. Memory should not be confused with your computer storage (hard drive space), because RAM contains chips in your computer which keep applications and processes active.
- That means when you open an application, it tells the computer to move it from your hard drive into RAM. As soon as the application is closed, it releases RAM and is free up memory for other apps.
- RAM can also be used to remember system settings. Do you know how the computer remembers what time it is, its display brightness, or system volume? That is PRAM; system information that your computer becomes; even when the power is off.
- PRAM is short for Memory ID Parameter Access and includes information about the selected start disk, display resolution, speaker volume, and other information.
- Unlike other types of RAM, PRAM is not configured when running off your computer. This is because a small battery is inserted which stops data when the computer is not charged.
Okay, so what is NVRAM?
- NVRAM is an updated Mac text for PRAM and is short for Non-Volatile RAM. As long as the NVRAM is not switched on, the settings do not change when the computer is turned off or disconnected from power. As far as troubleshooting is concerned, configuring either NVRAM or PRAM on Mac is the same thing.
- On PCs, motherboards have a type of 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 their BIOS settings by visiting the motherboard manufacturer’s website.
When do I need to configure it?
