Mac OS Catalina keeps disconnecting bluetooth devices

Hi, MacBook Pro 15" 2015 using Big Sur 11.2.3 and having the same issues.

I recently got Audio Technica ATH--ANC500BT and everything seems fine until I go to the sound preferences in settings. There everything freezes up for a solid 30 seconds then disconnects my headphones.

I have been unable to get the mic on the headphones working through my MacBook (they work on other devices) and I get a really loud static sound when something is playing and the audio output goes to 0. These issues only happen on my MacBook, and have tried next to everything to get it working. Really frustrated right now...

This can maybe help in some specific situations. But it doesn't solve the problem of BT headset disconnecting when switching from pure audio playback (AAC etc codec) to playback+mic (SCO etc codec) and back.

I've tried this and it didn't work for me. My Harman-Kordon Soundstick speaker still disconnecting all the time. It works fine with iphone 6s and MacBook 2012 with os Mojave, so it seems to be the Catalina problem.

Poporrico, thank you for posting this solution, I followed the sequence first thing today and so far so good - the magic mouse seems to be maintaining connectivity continuously - fingers crossed.

I was getting so annoyed with the disconnection that I was thinking of completely reinstalling the operating system from scratch and then reinstalling my applications from source and data from iCloud - done it once before so not that difficult except for the photos that took an age (two days) to upload (as I like to have a full copy on my MAC)

After that I guess it would be contemplating upgrading to a new MAC - (might do that anyway as not that keen on the new look MAC)

UPDATE:

After the update Big Sur 11.3.1, the problem persists but now, after the disconnection of all devices, it's impossible to reconnect them! Only the reboot of the Mac allow me to reconnect the devices.

Still the same on 10.15.4 - happens 6-8 times a day. Absolutely irratating.

I have followed most posts regarding this Bluetooth disconnecting and have held off reinstalling Catalina, but looks like I need to try.

So Apple, you have any suggestion to all the people posting here? Seems like you are just ignoring that Catalina has fundamental issues.

Facing the same issue after updating it to Catalina. I am using the Macbook pro late 2018 edition. Anyone found a workaround for this issue?

I have the same issue - AirPods, AirPods pros, Bose, none of them work. I've tried literally everything. I've got a 2017 iMac and am running 10.15.5. How is this not a bigger story by now?

2018 mac mini, Catalina 10.15.5, same story.

Mac mini 2018, iMac 27" 2017 - THE SAME **** ISSUE!!! Apple PLEASE stop issuing BETA software to users!!

@apple Im so disappointed, its my first experience on mac os, and i goin back to windows because i simple can't work on your computer.

I see now "it just work" is only another empty slogan.

Bye.

Reinstalling OS does not help! I clean my iMac and install it on a crean drive from Internet Recovery. Did not restore from Time Machine backup, just clean install!
