Bluetooth not working High Sierra

From that thread, here's someone who seems to know his way around OS X.

If you're a real hacker, James has a solution. But it involves patching OS X.

Best,

Folks, OS X 10.13.4 has now been released. When replying to this thread, please let us know which version you're using.

Bluetooth has not crashed since I installed this update a couple of days ago.

Thanks,

Tony (10.13.4)

I appear to have found a solution with my local store to my Bluetooth problem. The fault was that the Mac would drop the Bluetooth mouse and keyboard a few minutes after starting up. Sometimes it would re-establish itself, but sometimes I had to turn the Mac off at the rear button to get them working again.

The advisor at the store noticed that I had a lot of 3rd party programs that started automatically when the Mac was turned on. Although it was a brand new 2018 Mac, these had been transferred over from my last Mac by timemachine. The advisor stopped this long list of programs starting launching automatically and I haven’t had a problem since = 3 weeks ago.

As an aside, I have particular suspicions for the Garmin Connect program which caused my Bluetooth to drop almost immediately when I manually launched it a few days ago.

Take a look at the section titled "Last Resort"

Hat has sometimes helped: switch off WIFI. try to connect Bluetooth device, then switch on WIFI.

Hi Bronsrobin,

Try the following:

• Turn on and off
• Check settings in Bluetooth preferences
• Check your Bluetooth system information for any issues
• Quit Bluetooth process and restart it again...

Quit and restart processes worked for me!

Good luck...

Hi, just solved the same issue. My bluetooth speaker won't work which i used to have with my old macbook pro. Now with the High Sierra and the new macbook pro, it won't work... Just go to System Preferences... click on the sharing icon, check Bluetooth Sharing box.....works like magic

After months of searching these boards for an answer - someone posted this a couple weeks ago and then again recently. I followed and have had no problem in two weeks -HORRAY!!

"Just go to System Preferences... click on the sharing icon, check Bluetooth Sharing box.....works like magic"

I literally went through sooo many steps with the highest tier of 'Apple Specialists'. They even changed out HARDWARE which didn't fix it either. The ONLY thing that has fixed this bluetooth issue is reverting BACK to Sierra. I've had ZERO issues the last few weeks (daily before) since I went back. However NOW I constantly have to deal with my Mac trying to force me to upgrade to High Sierra. It is DEFINITELY something with their OS and them NOT acknowledging/fixing it is really disheartening and has made me lose my trust in Apple.

They did do tests. I had to send exact date/time down to the seconds of when it happened on my iMac. Keep in mind, my machine isn't even a year old and they've now changed parts that didn't need to be changed, gave me incorrect information. They told me my machine was in Texas and then the Apple Team in Boca called me a few hours later and no one had info correct anywhere. It was so messy. I was so over it. The engineers came back with I needed to wipe my machine completely (again - like 3x now) and start as a new machine. As long as I don't upgrade to High Sierra I have no issues. The minute I upgrade to High Sierra the issues happen. They know it's happening. Like I said their fix is to stay on Sierra and turn off updates so I'm not bothered by them. That's their end result for me. So here we are ...

I legit called every time it happened. I screen shot the time/date. Change your time to show seconds. When you see it happen or notice it screen shot that. Tell them to get you to engineering to test this. I think this is the only way we can get this issue fixed. I mean the Senior Advisor basically said people won't call 100x like I did because it's not worth their time. Most people will complain and just stop using BT unfortunately.

Good Luck!

I have the same problem. I've narrowed the issue down (for me) to after my laptop is been put in sleep mode. And this is all the time. The ironic thing is I wake the computer up from sleep mode by typing on my bluetooth keyboard. It takes about 30 seconds to a minute after waking up from sleep mode before I lose the bluetooth connection. The only 2 temporary solutions I know are:

1. Restarting my macbook
2. Once the macbook wakes from sleep mode, If I turn off and back on by bluetooth, then it stays connected.

It is not acceptable to reinstall the Mac.

It take s too much time and is complex with all installed components.

I like to do this as late as possible.

Best regards

Frank

Bluetooth not working High Sierra <https://discussions.apple.com/thread/8129665?answerId=32842717022#32842717022&ac_cid=tw123456#32842717>

Hi All

We have Apple Care Enterprise cover. at work. I've just spent an hour on the phone to Apple Care. My problem is not fixed but just for the record here is what we tried.

Also, I'll just add that I did a complete fresh re-install (delete HD and start again) of High Sierra 10.13.2 last night to see if that fixed things (it didn't).

I have a Bose Soundlink Mini II speaker and Apple Keyboard as the devices I wanted to find and pair. Both are discoverable when I look on my iPhone.

Here is what we tried today....

1. Reboot MBP - always the first thing they ask you to try

2. Toggle Bluetooth off/on (about 20 second wait) - almost as bad as step 1

3. Turn BT off, Removal of com.apple.bluetooth.plist and com.apple.bluetooth.xxxxxxx plist file, then reboot

4. Reset bluetooth module via bluetooth debug menu

5. NVRAM Reset

6. SMC Reset when you do the SMC reset, if your power supply is attached with the green light - the light is supposed to change to show the SMC has reset. Mine did not change ... so there is a chance my SMC reset is not working.

But, after the attempted SMC reset my MBP started to show up on my iPhone as a device that could be paired... but my MBP still could not see my phone. - odd

7. Booted into SAFE mode and tried to find bluetooth devices - could not find anything

8. Ran Apple Diagnostics via Alt-D at boot - this showed no issues

At this point they said there are two more options. A fresh install of OSX to a new partiton (or delete main partition and install.) but as I already did a fresh install they recommended the final option which is a Repair call and an engineer will come out and investigate as they think it may be a logic board issue.

They have opened a repair ticket for me and Apple care will contact me within 4 working hours to arrange when they can come and repair.

Will let you know if the engineer fixes it!

I have the identical issue with High Sierra. Since installing it I cannot transmit music from my MacBook Pro itunes program to any of the sources I previously did, in my case, two Vizio soundbars and a Bose speaker system. The bluetooth pulldown from the toolbar on my MacBook still recognizes these sources but when I then hit CONNECT it does not do so, even though the remote device indicated it was in the search mode before giving up.

I cannot believe that this is an inadvertent mistake on Apple's part -- it's just too big an issue to have been missed.

Only solution I can think of -- manual wire connection between MacBook and remote speakers.

Thanks a lot apple.

I have been having similar issues on my 15" MBP 2011 since upgrading to macOS 10.13.2. It most obnoxiously manifests itself as no longer being able to wake my MBP (which sits in a dock, and drives a Thunderbolt Display) from either my Apple Wireless Keyboard or Apple Magic Trackpad. I have to pull my MBP out of its dock, at which point I discover that the Bluetooth is "not available," and I have to reboot to restore Bluetooth functionality.

The other way the Bluetooth issue manifests itself is that the keyboard and/or the trackpad lose their connection, and become unresponsive. I have tried resetting the Bluetooth module, and have even tried performing a factory reset on my keyboard and trackpad, to no effect.

Reset like: Shift + Option + Right Click Bluetooth => Debug => Reset the Bluetooth Module ?

I have tried to reset and i still had the problem. 😟

But the solution from the "michael" link: "Last Resort" has so fare solved the problem.
