      2. If you still get a login screen after rebooting:

    • For flaky Mac USB (example symptom: speaker or microphone works a while, then fails),
      reset the SMC (System Management Controller) and the NVRAM (NonVolatile RAM).
      1. To reset the SMC: shut the Mac down, unplug the Mac from power, wait at least 15 seconds, plug the power back in, wait at least an additional 5 seconds, turn the Mac back on
      2. To reset the NVRAM: restart the Mac, immediately press & hold these keys: option, command, P, R (⌘⌥PR), hold the four keys ~20 seconds, or until the Mac boots twice.
