The SMC actually manages a lot more than what the Apple help page says.


You can try to Reset the Bluetooth Hardware Module:


  1. From the desktop, hold down the Shift+Option keys and then click on the Bluetooth menu item to reveal the hidden Debug menu
  2. Select “Reset the Bluetooth module” from the Debug menu listUser uploaded file
  3. When finished resetting, reboot the Mac.


Do you have the same issue when login in as guest?

You can also try a safe boot.

Try to reset the NVRAM & SMC:

Reset NVRAM or PRAM on your Mac - Apple Support

How to reset the System Management Controller (SMC) on your Mac - Apple Support


If the above steps do not work, try trashing the Bluetooth preference file (com.apple.bluetooth.plist) and then restarting.

Thanks!

I've Reseted NVRAM and removed plist.

Unfortunately it doesn't work.

I cannot reset SMC(Keyboard issue 😟) but seems, that it make no sense, cause SMC is responsible for:

  • Responding to presses of the power button
  • Responding to the display lid opening and closing on Mac notebooks
  • Battery management
  • Thermal management
  • Sudden Motion Sensor (SMS)
  • Ambient light sensing
  • Keyboard backlighting
  • Status indicator light (SIL) management
  • Battery status indicator lights
  • Selecting an external (instead of internal) video source for some iMac displays


Is there any other possible solutions?
