This is a common problem with big updates, where applications are usually delayed by a few weeks until they have a stable version. Unfortunately, some programs have not yet fully adapted to the macOS Big Sur operating system and can cause your MacBook to overheat. While we think that deleting an app is an unfair way of fixing this problem, it can be the only viable solution. If they were, then the NVRAM was successfully reset. Start by opening your System Preferences window and see if your settings were reset or not. When you’re done with all of that, you can go ahead and reconfigure your settings back to how you preferred them. On the other hand, for MacBooks with the T2 Security Chip, you can take your fingers off those four keys once the Apple logo appears and disappears from your screen twice.Your MacBook might seem like it will restart somewhere during the 20-second period.

Once it’s off, power it on and press the Option + Command + P + R keys right away.First, you’ll need to shut down your MacBook.Other than that, it doesn’t touch nor delete any of your personal files and apps that are currently installed in your MacBook. Having your NVRAM reset will revert your settings and preferences to their default orientation. The NVRAM acts like a hard drive for your computer’s settings, so your MacBook turns on the same way you powered it off. Moving on, your NVRAM is also another portion of your MacBooks memory that also stores your settings and preferences.
