Just got a new MacBook Pro (Retina, 13-inch, Early 2015), but there are several problems with bluetooth. Most of them occur when waking from sleep:

  1. Sometimes the bluetooth icon shows "Not available". The bluetooth hardware then also doesn't show up in System Information.
  2. Sometimes the bluetooth icon and preferences indicate that it's turned off, but nothing happens when I click "Turn on".

The only remedy for these problems is to completely restart the computer. In some cases, it hangs on the 'shutdown loading spinner', and then restarts with a kernel panic message. I attached the latest panic log below.

I tried trashing the bluetooth preferences and resetting the SMC, but that doesn't seem to permanently fix the problems.

Could this be a hardware issue?

  • Same issues - started happening a few months ago. BT always works fine after a restart, but when coming back from sleep it is catatonic or sometimes "not avaliable". The latter sometimes fixes itself after sleep/wake, but the only consistent fix is rebooting. ¯\_(ツ)_/¯

Same model, similar issues - though I wasn't getting kernel crashing, but occasionally get non-responsive bluetooth after wake from sleep. An alternative workaround to restarting is to force quit the blued process. This can be done either through Activity Monitor or on commandline killall blued.

I finally figured out the solution. Some bluetooth modules in the 2015 Macs have actual hardware problems. To confirm this, I ordered a replacement 2015 bluetooth module for my MBP 2015 from iFixit. My Mac kept crashing upon waking up from sleep delivering the same kernel panic message the OP had regardless of whether i put in the original 22015 BT module - or the replacement 2015 BT module from iFixit.

My friend gave me her bluetooth module from her 2013 MBP which looks physically different but still fits just fine in the 2015 MBP. I plugged it in and haven't had a single BT issue for nearly a week. Hope this helps. A 2013 MBP BT module is about $70 on eBay or iFixit.

This problem was extremely annoying and it seems multiple 2015 MBPs have it. I bought this 2015 model from my school in 2018 brand new(Apple shipped it to my school) - and it had the problem from day one. Shame on Apple for selling broken hardware 3 years after the fact.

I reset the SMC once more and changed the Wi-Fi to 802.11n on 5Ghz, after reading that it could cause interference. This seems to have fixed the problems so far.

Mid-2015 15" with the same problem on High Sierra.

My observations and solution:

  • It only happens when I have shut the machine off and then started it (not on restart or on wake from sleep).

  • Fix is to reset the SMC, sometimes have to do it twice.

Super annoying.

Finally I found someone else with this issue! This has been quite a problem.

I've worked around the "Bluetooth Not Available" thus far by doing the following:

  • Downloading "Bluetooth Explorer" from Apple's site (can't recall where but it was not easy to find)
  • When the problem occurs, open it, choose Tools > Get Local Device Info, then clicking "Re-Enumerate USB Device" until it comes back.

Have just had to deal with it crashing every time I let it go to sleep for an extended period of time. Seems to be more problematic when it's on battery but also happens sometimes when plugged in.

I'm not allowed to ask him directly for some dumb reason, but if the person given best answer could elaborate on how exactly to switch that Wi-Fi setting that'd be awesome. If it's on the router side unfortunately that won't help me, as I'm at a college campus.

  • Hi! Yes, unfortunately that is a setting on the router side. You cannot change this on a client. I've never found the reason for this issue with 100% certainty tbh. But I have a hunch that it also had something to do with waking up when an external display was connected. I've since moved on to a new external display, and never ran into the issue anymore. More than that I don't know unfortunately :(.

  • Yeah I have an external monitor as well and seem to have more issues when working with that. Mine was an HP VH240a, so maybe related? Not sure. Occasionally I've had other problems with displays, one which scared me as it went black and wouldn't fire up at all without several SMC resets. Resetting the SMC a few times seems to help my issues somewhat, but not fix the problem fully. Annoying, as I just bought that monitor...

Okay I found a way to fix the sleep-crashing issues:

Simply turn off Bluetooth before putting your computer to sleep.

Kinda annoying, but haven't had any problems since!
