OSX El Capitan 10.11.3 Bluetooth not available
<p>I am having some issues to get back to function my bluetooth (OS X El Capitan V.10.11.3, after the update), just presents a message as NOT AVAILABLE. I tried <a href="https://support.apple.com/en-us/HT203646" rel="nofollow">This solution</a> without any response. </p>

<p>Later, I tried to reboot the SMC like the following:</p>

  <p>Step #1. Turn off your MacBook (any of the above version). Step #2.
  Attach the power adapter to your Mac. Step #3. Press
  Control+Shift+Option keys and power button together for some time and
  then release the keys. Ctrl, Shift, Option, and Power Key Combination
  Step #4. Start the boot as usual. </p>
