El Capitan - Bluetooth Not Available

Hi Epithalamion, I'm really sorry to hear about your troubles! Mine - after the PRAM zap I've reported - is "still" ok although I'm now using the wired keyboard and mouse only - because i'm skeptical that the stability is definitive. At this stage I prefer being wired and up and running than potentially troubleshooting / debugging a brand new product on a daily basis. I really hate to do that. But I had to spend extra money to get wired keyboard and mouse, so I completely share your frustration and point of view. Sorry I can't be of any help to you.

HI Epithalamion, I'm also very sorry to hear about your problems.

On my side, like I mentioned, after the first and only PRAM reset I did, I haven't experienced this problem any more. I don't know yet whether this will solve the issue definitely but it seems to me by reading the topic here that the problem can materialize in many different ways. For sure a bug fix will have to be issued by Apple.

For what it's worth, I got a response from the bug fix platform advising me to reset the PRAM which is precisely what I had already done...

In any case I'd advise you to return your iMac and ask either for a refund or a replacement.

Same here I have just bought an identical machine and after a few days of running with no issues I had cause to shut down and restart the system and since then the same issue you report has manifested itself.

Apple support have suggested that I take it into the Apple store but I'm not inclined to tuck it under my arm, and carry it through 'Birmingham City Centre' (Hardly a laptop).

Guess its going to be a matter of waiting for yet another update or even El-Capitan's replacement in the Autumn.. Apple's support very friendly but with little substance and its very much "we care but only on the face of it" don't ask to do anything that might have a cost implication.

Had the same issue and tried SMC/Prefrences -- nothing worked.

I finally downloaded Onyx (http://www.titanium.free.fr/onyx.html) fixed permissions, ran all the maintenance scripts, and cleaned all the caches -- rebooted and am back in business.

Not sure which piece helped, but figured I'd share!

Spent all day looking for a fix for this problem & finally found this one & it seems to work.

1 restart your Mac

2 From the OS X desktop, hold down the Shift+Option keys and then click on the Bluetooth icon in the menu bar to reveal the hidden Debug menu.

3 Select “Reset the Bluetooth module” from the Debug menu list.

4 When finished resetting, reboot the Mac as usual and go through the process of connecting the Bluetooth device(s) to the Mac as you typically would, everything should now work fine.

This has been successful where the other techniques simply did not work for me. Good luck.

Thanks for the suggestion. Did not work for me. I tried it several times. When I hold down Opt-shift & click in BT icon I do not get debug option.

All I get is bluetooth not available and below it.."create diagnostic report on the desktop"

I tried resetting the NVRAM many times also and nothing works.. I am at a total loss.

A friend is looking into possibly trying to edit the NVRAM file & see if that works.

I appreciate everyones suggestions & ideas.

Some day I'll get this fixed, just very frustrating that so many are having the same issue and its posted on the boards & yet Apple cannot find a solution..

Bummer. I tried all of the different reset options, deleted plists, reset nvram & all these things gave me temporary access to the bluetooth. My guess is if you can get temporary access to it, it gives you an opportunity to access the debug menu. Have you had temporary access with any of your previous attempts?

Hey.

Only time I have any luck is if I boot in safe mode, then it works.. I'm going to try in safe mode & see if I can access debug while there.

Also might try to delete plist, then reboot in safe & see what happens... wish me luck.

Thanks again

Hank

I restarted in safe mode & BT working...I did debug & restarted normally & NO BT.. Next I did debug in safe, deleted plist, restart in safe...BT working.

restart normally...NO BT...very frustrating. At least I can by pass keyboard with cable & mouse.using old style wireless mouse.

But no Bluetooth Printer.. Hopefully someone(Apple ??) will come up with a fix real soon..

Thats a real bugger. Good effort for trying everything. I'm sorry my fix didn't work for you. Gladly my MBA is back to normal & still working. Just keep scouring the net & keep trying different things. Did you try downloading Onyx as was suggested in an earlier post. I did ran the diagnostics, but didn't fix my issue, it might fix yours.

I tried ONYX.. Ran the diagnostics & that didn't show or fix anything..I'm sort of afraid to run much else on there, since I'm not much of a geek & maybe it will do something negatively to the computer. I also ran the wireless diagnostics, thinking it might find something, which. of course, it did not.

Another suggestion was to edit the NVRAM file and insert the lines that another guy has listed in his. He had the problem but then solved it & he sent me the lines of the NVRAM that apply to Bluetooth. My NV file does not contain any reference to Bluetooth at all...

I have a neighbor, who is very very knowledgeable on the Mac & he's doing some research before he started editing the file.

I'll keep you informed if I find anything...Thanks for all your help !!

H

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

This is what I get
