Big Sur bluetooth problems

I had problems with my Bluetooth devices also after upgrading from Catalina to Big Sur. One of my Apps - VictronConnect, kept asking for the pin code for each Bluetooth Device, but it would not accept the pin code.

I finally reset the bluetooth password for each device in the VictronConnect.app and the problem went away. It appears that the configuration file for VictronConnect had become corrupted by the Big Sur upgrade. If there is a means of resetting the bluetooth pin code within the application you are using, then I suggest you try that first before resorting to more drastic measures.

Hey guys! I solved the problem executing this line on the console:

sudo rm -rf /Library/Audio/Plug-ins/HAL/

then I rebooted and everything worked!

Non apple headphones seem to have little or no issues with Bluetooth. It is the AppleID profile that is the problem. All apple users need to log out and log back in on all their devices after Sur update with Bluetooth issues.

Ok, what I did was this : reset the Bluetooth module and deleted any old Bluetooth device connections.

Then open Applications/Utilities

open Terminal file - a little coding window will open, copy & paste sudo rm -rf /Library/Audio/Plug-ins/HAL/

Restart your Mac & then try again.

Make sure you first 'Forget' the bluetooth Device in System Preferences/Bluetooth before you reset the pin code in the App.

Try not to auto-hide the menu bar in Sur.

Big Sur 11.1 update is out now.

I am having this issue with a Mac mini (2018) with all Apple devices, including wireless keyboard, trackpad, and AirPods Pro. Resetting the Bluetooth module seems to have worked.

Which Mac model are you and everyone using?

dropped Big Sur, went back to Catalina.

Reminds me of when the cubicles I was in had to go back to Win98 after the whatever-that-dysfunctional-update was.

Still have problems connecting AirPods Pro to intel based Mac mini. Sometimes it works sometime it don't. When it doesn't a forced reboot usually fixes the problem for a period of time. **** annoying!

Hi again -

a couple of reboots later and without changing anything my bluetooth headphone started to work again - No idea what changed since then...

Thanks for your help,

Similar situation here. Installed Big Sur on my iMac (2017) and MacBook Pro (2020). Everything works fine on the MacBook, but my iMac keeps dropping the connection to my bluetooth headphones and won't play sound through them at all. I've tried every possible fix I've seen online, and nothing's worked. Super frustrating. What's going on, Apple??

I use a logitech MX Keys and MX Master 3 keyboard and mouse. While joining the beta program for several months, I did not have this issue at all. But after the formal release, I thought, new range, let's give my MacBook Pro (2017) a fresh clean install. Since then, only troubles with bluetooth. It connects, freezes, connects, freezes, very annoying.

From one side, I'm happy, that I'm not the only one, so it is not sudden a HW failure, but on the other hand, many people are getting frustrated now. I hope apple soon comes with a fix for this.

Add me to the list who have an iMac (2017) that will not connect to Bluetooth headphones. iMac will discover the headphones but will not output sound to them or receive mic input from them. I have this problem with 2 different headphones from 2 different manufacturers (Bose and Aftershokz). Apple says firmware problems with headphones, but both worked fine with Catalina. Only the Mac OS changed. Seems like Apple OS issue to me. Hope they fix soon. Headphones did work on Mac mini with Big Sur.
