Bluetooth not working High Sierra

Hi there,


Updated my OS a while ago (2 weeks?) and my Bluetooth isn't working ever since. Turned it on and off a few times, didn't work. So I decided to reset the Bluetooth module, that didn't work either. Neither did removing all connected devices.


The problem is that my Bluetooth keep searching for devices, but can't find any.


Any ideas on how to fix this? People with similar problems?

MacBook Pro (15-inch, Late 2016), macOS High Sierra (10.13)

I just updated today and had to have Apple support walk me through a fix...


After restarting everything in sight. AND disconnecting and reconnecting everything. AND debugging the Bluetooth. Nothing worked. I noticed Bluetooth didn't even give me the option to turn off and next to "Devices" above the empty list was a spinning wheel... searching... for anything.


Apple walked me through powering down and rebooting the SMC.


The simple process (Mine: MBP 2015 15" Retina)

1. Power down

2. Hold SHIFT+ALT+CTRL (on the left side of the key board) + POWER BUTTON for 10 seconds

3. Release all keys

4. Press the power button to boot up


Bluetooth preferences opened up like new. I can turn them on and off and every bluetooth thing in sight was an option.


Typing this from my wireless keyboard now. Hope this helps.

And it continues ...


After sending to the engineers the engineers have come back with the following. I am to completely erase my machine, reinstall OS as a new machine ... AGAIN! However they don't believe me that we've done this because somehow they can't find the notes. IF it continues THEN they want to send it BACK to the Apple Store for MORE hardware testing. I ask them why they don't come onto you know THEIR forums here and see how many of us are having the SAME issues. I'm so tired of spending COUNTLESS hours on the phone and the back and forth. Like it's so exhausting I just want my machine to work as intended. If I tell them no then I'm not following their recommendations I am so at a loss. 😟

They trying really hard to get rid of our "vintage" MBP's

My wife and I both have the same as you - MBP mid 2011 17"

Best MBP with a big screen, they will forever keep sending bugs to our machines via updates to try to get us to stop using ours and buy new ones.

We also experience constant fan noise and I have also had to replace the graphics card twice.


Seriously.....annoying AF

You have my shared sympathy of course.


My dialogue with Apple support was farcical, in hindsight. To ask me to move away USB connected devices further away when note even powered!


They should do an error causal analysis on why such deeply fundamental issues happen, or not detected in testing (a child could spot this one), and not fixed with good speed. They would, it seems, not be training programmers to respect legacy code. I worked as an IBM systems and applications programmer. On mainframe software, making changes was a microscopically tightly managed process.


You might imagine that they would set up two machines for a soak test, one on Sierra and the other High Sierra. To drill down to the cause.


I am hoping that dialogues such as ours trigger such. Sooner or later, if not already, an Apple showroom demo will be inflicted with this problem.

At this point they won't even recognize this problem. I actually spoke to someone yesterday that said since they'd done everything for me that there was nothing else they could tell me. They won't take any responsibility. I've directed them here, TO THEIR FORUMS, and they tell me that they don't look at these or interact. That the development/engineers are the only ones that possibly look at that. I mean we're literally here troubleshooting FOR THEM and they ignore us and/or act like we're crazy. They will no longer even DISCUSS bluetooth with me! So they told me how to turn off my app update to not get High Sierra update requests multiple times a day. They linked me to how to do that via Twitter. Like they're not even TRYING anymore. I'm so frustrated and disappointed. Maybe we should all just tweet them with a hashtag or something to show them this is a freaking problem!?!?

Oh dear. This is worse than I thought.


It is very revealing that Apple CHOOSES to treat customers with contempt this way.


The same pattern seems to repeat - power and/or wealth creates chasmic distances between people. If Apple were a fledgling company, they would fix this problem with all speed.


Maybe I will try to experiment. I will see how my iMac functions in a different room that has no other devices in it. Except that :


1. This is doing Apples diagnostic work for them

2. If that fixes the problem, which then returns at my desk, what do I do next?

The man on the genius bar said that he could not swap my mouse for a wired one because the mouse was not faulty. After 10 minutes talking to his boss he could offer a trackpad replacement. But I pointed out that it too would drop out as it is bluetooth.


They are not aware of this problem and do not see it is well recognised.


I asked if I could invoice Apple for replacement mouse. Nope.


I will try to make a 4k video of the problem and put on YouTube to see how many others are suffering with this problem. I find it hard to believe that it is localised to a few if a bug of the OS. Maybe it is a big in combo with underperforming bluetooth hardware, but your swapped machine denies that.

Did you start experiencing the problem after upgrading to High Sierra? Do you have to reboot your Mac to resolve the problem? Or are you now using non-bluetooth devices as I have now had to. My shiny new magic mouse, fault free, sits on the side of my desk, unusable. Replaced by a bought mouse that lacks the nice glidepad on the Apple mouse. So I actually lose hardware functionality thanks to this bluetooth problem.
