What Is NVRAM and Why Reset It?

NVRAM, which stands for Non-Volatile Random-Access Memory, is a small amount of memory that your Mac uses to store certain settings. These include:

  • Display resolution

  • Speaker volume

Resetting your NVRAM can resolve a range of issues, including boot problems, display resolution settings, and issues with audio preferences. If you’re experiencing any anomalies with these settings, learning how to reset NVRAM on Mac can be a good troubleshooting step.

When Should You Consider Resetting NVRAM on Mac?

If your display resolution settings don’t seem to stick or keep reverting to defaults, it might be time to reset NVRAM. This can restore your preferred resolution settings.

Are Sound Issues Persisting?

If your Mac’s audio settings are erratic, such as the volume not adjusting correctly or the audio output device not responding, resetting NVRAM can often fix these problems.
