Resetting NVRAM (non-volatile random-access memory) on your Mac can help resolve various issues related to system settings, hardware, and peripherals. NVRAM stores settings such as sound volume, screen resolution, and startup disk selection.

Resetting it can be a handy troubleshooting step when you encounter problems like a frozen Mac, issues with external devices, or even if you just want to start fresh with your system preferences. In this tutorial, we will guide you through the process of resetting NVRAM on your Mac.

Before You Begin

Before proceeding with the reset process, it’s important to note that resetting NVRAM will revert certain settings back to their default values. This means that any customizations you have made in the past will be lost. Therefore, it’s recommended to take note of your current settings or preferences so that you can easily restore them later if needed.

Resetting NVRAM

To reset NVRAM on your Mac, follow these steps:

  1. Shut down your Mac by going to the Apple menu and selecting “Shut Down”.
  2. Press and hold the Option (⌥), Command (⌘), P, and R keys simultaneously.
  3. Keep holding down the keys until you hear the startup sound for the second time or see the Apple logo appear and disappear for a second time.
  4. Release the keys after hearing the second startup sound or seeing the Apple logo appear and disappear again.
  5. Your Mac will now restart normally. The NVRAM has been reset.

Verifying the Reset

After resetting NVRAM, you may want to verify if the reset was successful. To do this, follow these steps:

  1. Shut down your Mac again.
  2. Turn on your Mac by pressing the power button.
  3. Immediately hold down the Option (⌥) key until the Startup Manager window appears.
  4. Select your startup disk and click on the arrow to proceed with booting up.
  5. If your Mac starts up without any issues and the settings are back to default, it means that the NVRAM reset was successful.
