![]() Postings on Apple’s forums suggest shutting down the M1 Mac completely and leaving it off for 30 seconds to perform something like an SMC reset. ![]() The functions that the SMC handled are now taken care of by the M1 itself. M1 Macs don’t have a System Management Controller (SMC). But if you’d like to try, you can type the following command into a new Terminal window: nvram -cĪfter running the command, restart your Mac so the changes can take effect. And as with all Terminal commands, the usual caveats apply: You’re messing with OS X’s bash shell and could do irrevocable damage with the wrong keystroke. More advanced users can try using the Terminal to reset to NVRAM, though if you’ve reached this option the problem is likely bigger than resetting NVRAM. If you’re able to reset the NVRAM successfully with the wired keyboard, you can disconnect it and go back to your normal Bluetooth keyboard. If that doesn’t work and you’re using an external Bluetooth keyboard, try plugging in a USB keyboard instead. Disconnect all USB devices (except your keyboard, if it’s a wired keyboard), hold the power button down until the Mac shuts off completely, and then press it again and immediately hold down Command-Option-P-R. The most likely cause is that your Mac isn’t registering the key presses due to wonkiness with a USB device. ![]() If you hold down Command-Option-P-R at startup and you see nothing but a gray screen that doesn’t change for several minutes-no Apple logo, no progress bar, no second startup chime-don’t panic.
