It seems that this user took misoperation to do an NVRAM reset Macbook Pro and faced the risk of data loss. Here we will learn about NVRAM and the proper ways to reset it for your Mac.

Overview: What is NVRAM/PRAM Used for

Resetting NVRAM is the most frequent advice for resolving a malfunctioning Mac.

NVRAM, short for Non-Volatile RAM, is the upgraded Mac term for PRAM. The OS-related settings are kept in this small amount of memory in Macs, so your machine can start up quickly and function as intended. Resetting the NVRAM or PRAM on a Mac has the same operational effects since the settings remain the same when the Mac is powered down or unplugged since NVRAM is non-volatile.

NVRAM VS PRAM

In your Mac, NVRAM stores and keeps track of how a Mac is configured, including these settings:

Keyboard and language region
Display settings
Date and time settings
Volume settings
Kernel extensions
Startup disk

In Advance: Recover Your Data When You Need to Reset NVRAM

The state configurations of your Mac are stored in NVRAM/PARM, as was already described. Your Mac might operate incorrectly if the data kept in this random-access memory gets out of control.

When you need to reset NVRAM, it indicates that your Mac might have come across these questions:

Your Mac won't turn on black screen.
You can't adjust the display, date, and sound volume settings.
Your Mac won't restart after update
Your Mac won't shut down.

NVRAM and PRAM are powered by a battery separate from the Mac, so their data is kept even when the computer is turned off. However, the data stored in them relates to the OS. If you have to reset your NVRAM to repair your malfunctioning Mac, be careful about your data security during the fixing.

When the above errors emerge, protect and recover your data before resetting Mac NVRAM. You don't want to see all your data gone after fixing the problems.
