Q: El Capitan - Bluetooth Not Available

hankyc914, really sorry you're still having these issues !

Mine were solved with a single NVRAM reset.

Thanks McDoughnut for the tip with the debug menu. I'm keeping that in case Bluetooth misbehaves again.

After months of struggling with this, I turned off FileVault.... Only been a couple of hours but as this is the only change I made and the Bluetooth issue has not surfaced, I am feeling that this is very promising.

Hi  

I tried to reset NVRAM several times with no luck.... I have just about given up...  I have work arounds for my BT devices & till Apple fixes the issue

i guess I will have to keep using them

Thanks

Hi Mitch

I looked into my Filevault & it was never turned on..So mine must be a different issue than your..  Continued success with your Bluetooth.

Eventually I'll get mine back....maybe

Not sure I did it correctly, but did not work for me.. I unzipped all the files & dragged to Ktext utility...nada !!!  Maybe IU didnt do it right   I'll try it again

Thanks anyway

This is what I get

disable the SIP to copy the files

Im not much of a tekkie..  What is SIP and how do I disable?   Thanks in advance

I had the same problem...no Bluetooth...happened all of a sudden. Shut down...waited a few minutes...then powered up. Bluetooth back.

Installed new OS 10.11.6 and same issue.  Tried to reset NVRAM.  No luck..  Funny thing is BT keyboard & mouse work, but can only use basic properties.  Function keys don't work and only single left or right click on mouse works, even though menu bar shows "Bluetooth Not Available".  Weird  and still if I restart in Safe mode it works...I wish Apple would find a fix already  ....

I just purchased a 13-inch MacBook Pro, spent the better part of my evening trying to import my data, settings, applications, etc. from a desktop iMac Time Machine backup and then when I finally got things up and going was halted by this same "Bluetooth Not Available" message. Researched all the same methods of troubleshooting you have with no results at all, didn't even work for a little while. Finally, I realized I had my power plug and an external 27" display plugged into the laptop and wondered if I removed all connections to the laptop (as suggested in another troubleshooting article to remove all USB devices) would that work. And it did. So if you are stumped like I was, disconnect everything from the machine and startup from the battery (on a MacBook Pro) and hopefully it will work for anyone else experiencing what I experienced.

to me it happened after sleep, only sometimes, it's intermittent. the only two things  which worked were rebooting the OS X and/or reloading Bluetooth module.

as mentioned in http://apple.stackexchange.com/questions/156863/bluetooth-issues-after-sleep-in- os-x-yosemite-10-10

do this in Terminal, when BT does not work again and you don't have to reboot:

sudo kextunload -b com.apple.iokit.BroadcomBluetoothHostControllerUSBTransport
sudo kextload -b com.apple.iokit.BroadcomBluetoothHostControllerUSBTransport

reset SMC or PRAM did work - not because I reset it, but because a reboot was also involved.

I'm thinking if this has something to do when Mac goes to sleep when being connected... but it's only happening on my Macbook Pro mid 2012. not with iMac late 2012
