Bluetooth keeps disconnecting after update to Mac OS Catalina

Thanks alot for this suggestion. I tried it on my MacBook Air 11, and found that a restart was also necessary to get a benefit. I also did all the debug resets via clicking the bluetooth icon in upper bar (while pressing opt-shift) and reconnected. At first, it seemed to worked well. Closed the lid to go to sleep, and reopened this morning, and continued on and all seemed well for about 45 mins or so, and then the dropouts started happening again. I guess a restart might be a solution, but this is seriously getting annoying.

So i did a little chatting with apple people and discovered the issue, hope this helps others too.

It was an issue with one of my software. This issue only came after installing Catalina on my MacBook Air '15.

What I did was created a test user https://support.apple.com/de-de/guide/mac-help/mtusr001/mac on my mac (which is like a separate and new account with no user installed apps/software), then listened to some youtube music for 30min - 1 hour (I played FiFA '20 during the wait thanks to Corona). The audio device never tripped. So the apple advisor said if that happens, it because of a trippy app/software in your main user that's causing this. So you can either uninstall apps/softw that use your audio devices like WhatsApp web, Zoom, Adobe cloud apps, spotify, vlc etc, restart your pc and see if the problem is still there. Then reinstall the apps one by one and see which app is causing the trip.

Another issue could be a pending update for one of the apps that use your audio device that needs updating. In my case, I only uninstalled Spotify, WhatsApp, Premiere Pro, After Effects & Audition. I reinstalled them all and all has been good.

Hope this helps ya'll cuz this gave me the craziest headache.

If it works OK on another mac user ID it is probably not apps because generally they are shared amongst users.

Something in your ~/Library folder is more likely causing it and to be honest it will take less time to switch users and move your documents and media files.

Uhm no nah, u don't move any media files. U just create a new user and test it out there. Its a quick and easy step, the only hustle would be tryna figure out which app uses both audio. But based on a couple other comments, its probably these chatting apps that are causing the bug. Just like on mobile, u uninstall the app (but keep the apps data/preference settings), restart the pc and reinstall it and ur good.
