(macOS High Sierra 10.13) Bluetooth devices disconnects by itself

This is not a hardware problem. Been running a Mac mini server (2011), never had a problem before High Sierra 10.13.2 now at 10.13.3. Solved this problem first time it happened by rebooting. Now I have reset the Bluetooth module, I will see what happens...

@sarawgc - most western countries have some general consumer protection laws that say anything you buy must be fit for purpose. If you bought the Mac, keyboard and mouse at the same time then you would expect them all to work properly. If they don't, you would almost certainly be able to return them for a refund. It depends a bit on the store you bought it from as to how co-operative they'd be. Also if you keep calm but talk loudly enough that other customers can hear your conversation they will be keen to get it resolved!

Did you have any joy resolving your issue? I have the same problem only on an old machine , I keep getting told the machine is too old and the parts must be failing though Im pretty sure its software based as it stops a lot when the mouse is left on a hyperlink, I almost put it down to a you tube issue, but ....

Very frustrated by it all and have been told to take it to an apple store , but the nearest is 5 hours away!

Thanks

Hate to say it but I made the mistake of taking your advice; as soon as I selected debug/remove all devices, the menu from which I was to reset Bluetooth module...disappeared.

Now I have no BT connectivity. Wired mouse and quite a bit of work to do.

This is running 10.13.3 on a late 2015 iMac.

Help!

Try this guys.

Open Terminal type (or copy and paste):

defaults write com.apple.BluetoothAudioAgent "Apple Bitpool Max (editable)" 80 
defaults write com.apple.BluetoothAudioAgent "Apple Bitpool Min (editable)" 80 
defaults write com.apple.BluetoothAudioAgent "Apple Initial Bitpool (editable)" 80 
defaults write com.apple.BluetoothAudioAgent "Apple Initial Bitpool Min (editable)" 80 
defaults write com.apple.BluetoothAudioAgent "Negotiated Bitpool" 80 
defaults write com.apple.BluetoothAudioAgent "Negotiated Bitpool Max" 80 
defaults write com.apple.BluetoothAudioAgent "Negotiated Bitpool Min" 80
sudo killall coreaudiod

I have the same exact issue with my MBP mid 2012 retina 15". I've suffered with this for literally years. I'm not using any BT mouse or other BT accessories, but I am using Bose QC35 headphones and a Bose Soundlink BT speaker. I experience intermittent dropping and difficulty reconnecting, almost on a daily basis. I have noticed though, sometimes plugging mine into power magically allows it to reconnect. Sometimes unplugging it reconnects. Very strange issue indeed.

well of course not. why would I do that? LOL. That's usually something i do all the time, but I did not do it after the terminal commands. I have now redone the terminal commands, forgot the device, rebooted the computer and repaired the headphones. will keep yall posted on any further developments.

Are you on Q35 II or I? Looks like there is an update to the headphones for a multipoint bug. Make sure driver are up to date on ur Mac too Apple - Support - Downloads

Scott - Whats this independent website address please?

Sorry, I didn't see your reply until this morning (email rules, you know).

Scott.

Also, to confirm the problem continues when booting up in safe mode.

My mouse and keyboard are rechargeable, no batteries and are fully charged most of the time. I don't think mine is battery related sadly.

Just wanted to say that I'm also very interested in seeing what they say. Thanks in advance for keeping the thread here in the loop!

Same here. High Sierra on MacBook Pro 2013 loses BT Headphones and BT Keyboard parallel nearly every day.
