Performing a SMC & NVRAM Reset on Apple Silicon (M1 & M2)
You can’t reset the SMC, because the M1 Mac doesn’t have a System
Management Controller. You also can’t manually reset the NVRAM / PRAM because
your Mac does this automatically, if needed, during every startup.
Best course of Action is to Restart Your Mac.
