How to fix
“Bluetooth Not Available” Error
on Windows

Hello. I was trying to connect the Apple Magic Mouse to my Mac computer and it displayed an error saying "Bluetooth Not Available". Restarting Bluetooth doesn't help and I cannot find Bluetooth panel in the System Preferences as well. Can you help me, please?

"Bluetooth Not Available" error on Mac OS X prevents you from connecting any wireless device to your computer. It doesn't matter whether it is a mouse, a keyboard or headset. You can also notice that System Profiler displays "No Information Found" once you try to search for Bluetooth hardware module[ref en-1]. Besides, Bluetooth panel is not accessible on the System Preferences, and its icon appears with a crooked line through it. 

We have noticed that Apple community encounters "Bluetooth Not Available" error after updating Yosemite to El Capitan or the latter one to Sierra OS[ref en-3]. All the indicators mentioned above show that this is not a simple issue. Therefore, if you try to mend the problem of random disconnects of your wireless devices, restarting Bluetooth[ref en-2] might help.

However, to fix "Bluetooth Not Available" error, you will have to discard Bluetooth preferences and pair your desired devices with your Mac again. Those who are not experienced enough should follow the guide below which will briefly explain how to re-sync Bluetooth gadgets in Method 1.

In some cases, even this may not help. Likewise, we attach instructions on how to reset the System Management Controller (SMC). If the first method failed, make sure to try the second technique. Note that Method 2 might fix "Bluetooth: Not Available" error, but it works differently for each type of Mac. Hence, you should follow the guide below and pick the instructions which are designed for the Mac computer you possess.
