M1 iMac MacOS Sequoia how to do SMC and PRAM resets

You reset the SMC on an Apple Silicon Mac by either restarting or shutting down and restarting.

Resetting the PRAM/NVRAM doesn't apply to Apple SIlicon Macs.

Apple Silicon Computer ?

This computer does Not have a SMC

NVRAM reset - some thing

The closest to doing an SMC Reset would to shut down the computer

If you have Mac with Apple silicon >> SMC

Reset NVRAM on your Mac >> NVRAM

Just to be clear, Apple Silicon Macs do not have separate SMC or NVRAM chips. However, you can do the equivalent of resetting the SMC as mentioned. And it is possible to change settings that were handled by the NVRAM chips using the Terminal.

You can use the following Terminal command to clear the NVRAM.....it may not be able to clear some settings such as computer name and such which is normal.

sudo  nvram  -c

This command will prompt for your admin password. Nothing will appear on the screen as you type the password, so press the "Return" key to submit the password. If the command itself does not fail except for certain settings/keys, then you will need to reboot the computer in order to pull the default NVRAM settings.
