Hi guys and welcome to 123myIT. In this video, we will show you how to fix your Mac by resetting NVRAM.
Before we get started, what is NVRAM? NVRAM is a small amount of memory that your Mac uses to store certain settings. Therefore, if you are having issues with Sound Volume, Display Resolution, Start-up disk selection, Time zone and Kernel Panic then resetting NVRAM might help.
Ok to reset the NVRAM you need to hold down Option, Command, P and R buttons on your keyboard as your Mac restarts.
Go up to the Apple menu and restart your Mac now and you see your Mac restarting. Quickly, hold down the Option, Command, P and R buttons. Because you will hear the first Apple chime continue to hold down the Buttons and you should hear a second Apple chime. Great job the NVRAM has been reset now let go of your buttons now.
You can log back into your Mac and hopefully your issues have been resolved! Other helpful reset videos are fix MacBook Air with T2 chip. The T2 chip is that funny looking power button on some of the Mac computers.
