How to reset NVRAM on a Mac

Learn about the NVRAM on your Mac computer, when you need to reset it, and how to reset it.

What is NVRAM?

NVRAM, also known as non-volatile random access memory, is a small amount of computer memory used to store certain settings in a location that MacOS can quickly access. The settings stored in NVRAM depend on the type of Mac you are using and the type of device the MAC is connected to.

The information stored in the NVRAM may include:

• Speaker volume
• Screen resolution
• Startup Disk Selection
• Recent kernel crash information (if any)

Resetting NVRAM may be helpful when encountering issues related to these features. For example, if your Mac starts from a startup disk other than the ones specified in Startup disk preferences, or if your Mac briefly displays a question mark icon when it starts up, you may need to reset NVRAM.

How to reset NVRAM

To reset the NVRAM for your MAC computer, follow these steps.

If you are using MacBook Pro (end of 2016), the steps will be slightly different. If you need instructions, skip to the next section.

1. Turn off your Mac.
2. Locate the Command (?), Option, P, and R keys on the keyboard.
3. Turn on your Mac.
4. When you hear the start sound, press and hold the Command-option-p-r key immediately.
5. Hold down these keys until the computer restarts and the start sound is issued again.
6. Release the keys.

After you reset NVRAM, you may need to reconfigure settings such as speaker volume, screen resolution, Startup Disk selection, and time zone information.

If you still have problems with these features on your MAC desktop computer (such as IMac, Mac Mini, or Mac Pro), you may need to replace the motherboard battery. The motherboard battery on the desktop computer is used to help save the NVRAM settings when the MAC is powered off. You can bring your MAC to the Apple Store or an Apple authorized service provider to replace the battery on your motherboard.

How to reset NVRAM on the MacBook Pro (end of 2016) model

If you're using a MacBook Pro (15-inch, end-of-2016), MacBook Pro (13-inch, end-2016, four Thunderbolt-port) or MacBook Pro (13-inch, end-of-2016, two Thunderbolt-side ), follow these steps to reset the NVRAM for your Mac computer.

1. Turn off your Mac.
2. Locate the Command (?), Option, P, and R keys on the keyboard.
3. Turn on your Mac.
4. When you turn on your Mac, press and hold the Command-option-p-r key immediately.
5. Press and hold these keys for at least 20 seconds to ensure that the MAC completes the process correctly.
6. Release the keys.

After you reset NVRAM, you may need to reconfigure settings such as speaker volume, screen resolution, Startup Disk selection, and time zone information.

On older MAC computers, similar information is stored in parameter RAM (PRAM). Resetting the NVRAM with the same key combination on an Intel-based Mac is equivalent to resetting the PRAM.

Power-related settings are controlled by the System Management Controller (SMC) on your Mac. If you experience problems with your computer powering on, sleeping, waking, charging your Mac laptop battery, or other power-related symptoms, you may need to reset the SMC instead.
