If you're experiencing issues with your Mac—such as problems with display settings, volume control, or startup disk selection—resetting the NVRAM (Non-Volatile Random Access Memory) or PRAM (Parameter RAM) can often help. This simple troubleshooting step can resolve various glitches and improve overall performance. In this post, we’ll walk you through the process of resetting NVRAM/PRAM and discuss when you might need to do it.
What is NVRAM/PRAM?
NVRAM and PRAM store specific settings that your Mac needs to access quickly. These include:
