Catalina bluetooth issues - audio output switches intermittently

After upgrading to Catalina, my Macbook Air has audio output issues when the Bluetooth is connected to Sony WH-1000MX2 headphones. Suddenly, the audio connection switches to the internal speakers and the output can't be changed. The immediate solution is to turn off/on the bluetooth on the Macbook and reconnect the headphones. But after a while the problem reoccurs.


I have tried to problem solve by the following processes:


  1. Accessing the debug function (click the the bluetooth icon in the menu bar whilst pressing alt+shift). Remove bluetooth devices. Reset the Bluetooth module. Delete the bluetooth plist files in the library (/Library/Preferences + ~/Library/Preferences/ByHost ). Restart Macbook. Reconnect the device.
  2. Reinstalling Mac OS Catalina


The actions mentioned above does not solve the problem.


Any help will be appreciated. Thanks.

Since the apple engineers won't do anything about this issue anytime soon, I found this trick helped me. I went to https://developer.apple.com/download/more and searched for additional tools on the search bar, and downloaded the latest xcode 10.2. In the folder Hardware look for bluetooth explorer and open it, it opens in the background so you need to search for it. Then open the Tools/Audio options tab, and select "Force use of aptx" box. Then I found the bluetooth doesn't drop after couple of mins.

I also have this issue.


MacBook Air (Retina, 13-inch, 2018)

macOS 10.15.2


The following devices will not stream audio over Bluetooth:


Airpods 2

Airpods Pro

JBL Charge 3

Bose QC35


All products work on other devices including iPhone XS and IPad Pro.


Apple, this is extremely frustrating and completely unacceptable. Please advise on a fix ASAP. Or should I take my machine to the Genius Bar and have them try and resolve?

Hi,

I also have similar issue.


Macbook Pro 15 (2019)

macOS 10.15.2 (Catalina)


I've assigned my Magic Mouse, and when I leave it without moving the cursor, it become "not connected" and "connected" back after 5 or 10 seconds of moving it.

What I did :

  • Removed com.apple.Bluetooth.plist
  • Reset PRAM (Command + Option + P + R)
  • Removed device
  • Tried with my second Magic Mouse (I have both, version 1 and version 2)


I still have the issue since Catalina upgrade.

Bluetooth devices :

  • Magic Mouse 1
  • Magic Mouse 2


When I use both mice on my other Mac without Catalina (MBP13 retina, MacMini), I don't have that issue.


@Apple : What do you plan to solve this ?

I have Bluetooth issue as well, but only tested currently with a Logitech MX Anywhere 2s mouse.


I have 3 Macbooks next to me.


Macbook Pro 13 (2016) Working.

Macbook Pro 15 (2018) (Driver Version [Version 7.0.2f4 (V86 C4407)] Working as well.

Macbook Pro 16 (2019) (Driver Version [Version 7.0.2f4 (V44 V4176)] The device connects and 1 second later disconect my mouse.


Delete of BL file and PRAM reset did not work. Same as full restore of OSX.

I have this issue too. It's not just with my Sony WH 1000XM3s, also test with Sony MDR ZX700s, Bose QC25, and Samsung buds. This happened on my 2016 Macbook Pro 13 touchbar after upgrading to Catalina. Recently bought a brand new 2019 pro which was fine for a few days, and the problem reoccured on my new mac after upgrading again too. This is infuriating.

I have the same Issue with AirPods 1. Gen and just bought the Sony WH-1000XM3, which also get thrown out of audio output after a while. I am following this thread since the beginning of December 2019 and nothing has happened to solve the problem from apple's side. This is so frustrating and disappointing. Love Apple products, but the software gets more and more failures after each major update. Just DON'T release it, when it's not working a 100%! Can't image buying a $60k Mac Pro and having a bluetooth connection problem with wireless earphones. Apple - get. your. s***. together!!

Hi Apple,


Please stop blaming other devices and take ownership for your bug. It is extremely worrying that you don't take responsibility for this issue, because this means you're not even going to try to prioritize it. Your product is supposed to connect to all bluetooth devices as most products, even cheaper ones do.

You can't blame it on sony, hardware on anything else.

Here are the facts:

  • I used my company's macpro to connect to Logitech speakers via bluetooth.
  • I updated to Catalina and now my sound gets muted every two minutes even through the speakers show connected.
  • There were no bluetooth issues before
  • Here's the interesting bit: Your other product Iphone XS has no problem connecting and providing stable sound through those speakers.
  • Mystery solved.

If I don't get a clear response, I'll do my best to make a formal complaint. I'm sure the Uk consumer rights would be interested as well. This needs to be addressed publicly!

Not without disconnecting the bluetooth, reconnecting and having to do it again every 5~20 minutes, if I'm lucky it may stay connected for as long as an hour. Bluetooth still appears as connected but output switches to internal speakers and can't be switched back. Headset controls don't work either even though both devices seem to think they are connected.
