Big Sur bluetooth problems

Hello, I just realised why I couldn't get this fix to work either... I needed to include Macintosh HD/System at the start of the terminal command: "sudo rm -rf Macintosh HD/System/Library/Audio/Plug-ins/HAL/" Entering this followed by a restart worked perfectly for me. All bluetooth audio devices now back in action.

Thank you to whoever it was that posted that original fix!

I “Shutdown” the MacBook Pro 2017. Started the Mac, ran the diagnostics by pressing the “D” key on startup. No issues found. Still having Bluetooth problems with AirPods Pro, Wirless Keyboard and Mouse.

Apple, please fix this problem before launching a new product for the winter. Work from home depends on it.

Yes, very frustrating in the WFH situation when being on a conference call and everything drops.

Also have a situation when iPhone has an incoming call that also rings on my Mac mini and then not being able to answer the phone on my Mac mini. Worked with Catalina but not with Big Sur.

SORTED !

I have followed the instructions to Delete all plugins in "/Library/Audio/Plug-ins/HAL/" and restarting fixed this issue.

I had the problem with two sets of BOSE headphones - a 35 and the newer 700 series. My Mac is a Mac (Retina 5K, 27-inch, Late 2014)

Im having the same exact problem with the bluetooth connection. Im also having an issue since updating my 2020 MacBook Air to Big Sur my computer crashes about ever 5 min if left inactive. I have deleted all third party plugins and it still happens. VERY FRUSTRATING since I had a 2014 MacBook Pro that never had any issues! Come on Apple we spend 900.00 on these machines and you can't even get the software right!

I found for me it was specifically the InstantOn.driver which was installed my Rogue Amoeba - Piezo. Deleting this from /Library/Audio/Plug-ins/HAL/ fixed my issue with Bluetooth headphones connecting and then disconnecting after a few seconds.

Same here on my 2017 MacBook Pro. Log out of all your apple devices and log back in. Also disconnect WiFi then connect Bluetooth devices. Reboot. Turn on wi-if after Bluetooth device reconnect. Keep Mac running for at least 1-2 hours . More the better. It seems to help a little.

Today I bought new Sony BT headphones and it works perfectly with my Air M1. So does my Linux PC. My Windows 10 PC and my Android phone are not working with the M1, so I don't know what is the problem with those.

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.

HI. In PLUG-INS J have not any folder HAL. J have COMPONENTS and MAS and VST and all of them are empty. BT connect correctly my BOSE and AirPods but they don't play. What to do? thanks for your help

Just the same with me, that bunch of empty folders which have no impact whatever. I have Bose earphones and a Bose bluetooth speaker, neither of them usable with my MacBook Air. Please give us an update soon Apple, this isn't on.

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!

I'm quite sure that's not the case, they didn't know so they made something up! There seem to be an awful lot of us who can't connect bluetooth after updating to Big Sur. As my MacBook ia new I'm quite sure it's nothing to do with hardware but everything to do with an update that's not been fully tested, It's really annoying me as I use my bluetooth speakers and headphones all the time and this MacBook can't even find Apple AirPods..

I've just started using a Mac less than a week, I can't believe I'll have to go back to my old PC if I want to listen via bluetooth.

I agree. I am very angry about all this. This should have been tested. I am on zoom all day with instructors at a university, and now my Air Pods do not connect for full use. I got them to connect briefly today, but there was no sound. I have two new MacBook pros, and the bluetooth stopped working the minute I upgraded them. I am frustrated to the point of tears. I have used Mac since 1983, and the service and products are not what they used to be. I cannot believe this did not come up in beta testing.

Support.Apple.com is useless. Search for MacOS Sur Bluetooth and in spite of so many people having this issue, nothing shows up. Also, other issues show up in random order with no way to filter. Looks like everybody is being taken for a ride to Timbuktu.
