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.

I already did that. It actually stopped working AT the Apple Store too. Like it was literally doing the same thing we're experiencing WITH an Apple Advisor. That's why they changed my hardware. Still ... same result. Since I went back to Sierra about a month ago and have not had the issue since. Just ***** I can't use the current OS because of their issue :/

I bought beatsX wireless earphones today and paired them right away. Tried to take advantage of the w1 chip and try to connect to it on my 2017 touch bar Macbook pro, didn't work. I tried connecting them as a regular pair of bluetooth ear set, they connect for a second, you choose them under audio output settings and they disconnect immediately. I tried it on an older Mac that is not updated to Sierra, works perfectly. SO obviously, there's something wrong with the bluetooth on the Macbook. I have a Keyboard and a trackpad connected to it, they work fine. I also tried another bluetooth headset and they don't stay connected either. There's something wrong in 10.13.3, if it works in a past version of Mac and also works on my iPhone 7. The beats are updated and also The Macbook is updated as well. I talked to Apple chat, obviously no help. I reseted the beats, no help.

Seems I really should make a clear 4k video of the problem my end. Currently I am trying the iMac with no USB cables plugged in (they were plugged in before but not to active devices). Since then, no bluetooth dropouts. Will try a few days then plug them back in one by one. It may be that they act as aerials, interfering with bluetooth frequency.


But I cannot leave USB cables unplugged to work around an Apple problem. And Apple cannot expect this.


I hope that if I post a very clear demo video that the scale of the problem can be gauged. That the 1st person in the coffee shop I spoke to about this is having the same problem, then I find it hard to believe it is rare.

Since updating to High Sierra my Bluetooth is not working most of the time. I had ZERO issues before High Sierra and now I have to continually restart my MacBook to get Bluetooth working - if it works after restart. Sometimes it works, sometimes not. Please fix this Apple - annoying as **** and totally unnecessary. Early 2011 MacBook Pro 17".
