Symptoms

  • Can't charge MacBook

Solution

Try power button reset. Then try SMC reset. If neither has effect, disconnect battery or discharge battery to 0.

The SMC update during a MacOS upgrade may silently fail leaving no power access to the USB ports. This happened to the author after a Catalina 10.5.7 update. Multiple power button resets and SMC resets may not work. Genius bar is baffled. Disconnecting/discharging the battery to 0 allowed the SMC to fully reset.
