Resetting NVRAM can be a troubleshooting step for various issues, including display problems, erratic behavior, or issues with startup disk selection. It's often recommended when troubleshooting common Mac-related issues.

Common Methods for NVRAM Reset

Resetting NVRAM typically involves a few simple steps, depending on your Mac model.

Using Keyboard Shortcuts

On most Mac computers, you can reset NVRAM by following these steps:

Shut down your Mac.

Turn it on and immediately press and hold the following keys for about 20 seconds: Command (⌘) + Option (⌥) + P + R.

Release the keys after you hear the startup sound for the second time or see the Apple logo appear and disappear for the second time.

Using Terminal Commands

Alternatively, you can reset NVRAM using Terminal commands, especially if your Mac doesn't respond to keyboard shortcuts. Here's how:
