Mac Troubleshooting Tips

Fix your Mac with these simple troubleshooting tips

Reset NVRAM or PRAM on your Mac

Sometimes your Mac’s Parameter RAM (PRAM) or Non-Volatile RAM (NVRAM) becomes scrambled and needs to be reset. Settings stored in the PRAM or NVRAM include sound volume, display resolution, startup disk selection, time zone, and recent kernel panic information.

The settings stored in PRAM or NVRAM depend on your Mac and the devices that you're using with your Mac.

• For Mac computers with an Intel processor, go to https://support.apple.com/en-us/HT204063.

• Apple Silicon (M1) computers use NVRAM differently and can no longer be completely reset.

Reset the SMC of your Mac

Resetting the system management controller (SMC) can resolve certain issues related to power, battery, fans, and other features.

• For Mac computers with an Intel processor, go to https://support.apple.com/en-us/HT201295.

• Apple Silicon (M1) computers do not have a system management controller (SMC).
