MacOS 12.0.1 Monterey Bluetooth issues

Hi, I am an application developer for Mac. Our application uses bluetooth to connect to our hardware devices.

Since the upgrade to MacOS 12.0.1 Monterey Bluetooth is broken customer wide. Hence pairing works but our driver cannot connect (code worked for MacOS 10.7 - 11.3). The internet reports a lot of Bluetooth issues related to Broadcom BT on Monterey and the Bluetooth Framework has changed significantly by Apple.

  1. Where can I find detailed information about Apple's Bluetooth changes ?

  2. Should I just wait until Apple fixes this from their side ?

Any other guidance is appreciated.

Thank you?

I am facing similar issues. My mac mouse stops to scroll occasionally and have to reconnect. Also, my TWS go into mute mode without any reason or action from my side. I Hope Apple fixes the issue soon.

Here same problem "No name or address" in the console log.

The Bluetooth Core on Monterey is buggy.

Just half an hour ago, I had to restart my iMac because the mouse did not scroll anymore. I just thought that my mouse had died, but after restarting, everything worked fine. I created a ticket a couple of days ago and got a reply pretty fast. It was escalated to the Bluetooth team, but I did not anything back from them.

I also have some problem with my bluetooth on my Macbook air 2020 M1. My mouse moves very slow. Firstly , I think my mouse was died, so , I bought a new apple magic mouse , but this problem is still there. I finally find a way to fix this, just turn off my wifi, then the bluetooth mouse will work well again. I do not have this problem before yeaterday, I do not know what's wrong with my Mac. I think this might be relate to WiFi and Bluetooth interfere, but I don't know why this suddenly happened yesterday.

Accepted Answer

Our production application has also been unable to create Bluetooth socket connections since the last update. We have validated this issue with two independent API for Bluetooth connection -- all of which are fully functional up to and including Big Sur.

Customers having upgraded to Monterey are all unable to connect their devices to our desktop application. This is critical and we are waiting for a fix.

I am also having issues connecting iPhone's via Bluetooth since upgrading to Monterey. It will Pair but will not stay connected. I also have received the message: " MBP is not supported" when attempting to connect directly from an iPhone. I did not have this issue on MacOS Big Sur (11.5)

I have tried connecting with the following on three different Intel MBP's all running Monterey (12.0.1):

  • iPhone 7P / iOS 14
  • iPhone 8 / iOS 14
  • iPhone 12 / iOS 15

I have attempted to correct the issue by following multiple suggestions:

  • Reset NVRAM
  • Reset SMC
  • Remove .plist

None of the recommended steps are working - hoping that Apple is all over this and will be releasing a fix shortly.

It would be helpful if a Moderator would acknowledge this as an actual issue that Apple is actively working to resolve or if I need to restore Big Sur to make this work again.

Hi!

I don't have a solution but want to report the same problem here. Maybe this helps to get more attention. We also use bluetooth to connect to our hardware. Worked until 11.6.

Same here. It is even worse. I cannot even switch Bluetooth off.

I've already contacted the support and yet there is no solution. Even a fresh installation via recovery did not work. Funny details: I have a M1 so I can run the nrf connect app from nordic and there I can scan. But If I try to scan with a Qt application or from the Bluetooth configuration it is not running anymore. Seems, that Apple did not test Bluetooth low energy at all in this release.

same problem, waitting for fix it.

Same here. I have a Macbook Air M1 2020. The system automatically upgraded to MacOS 12.0.1 about 2 weeks ago . Since the upgrade, whenever I do a cold boot, the mouse will be unresponsive and often the OS will crash and restart. The bluetooth mouse is Logitech M557. Really annoying problem. I am surprise Apple did not offer a fix given the problem was reported over 2 weeks ago.

This error is driving me insane as I thought it was my Logitech mouse problem but obviously not as it seems to be a MacOS problem.

Same here. We have the Problem with 3 of our devices in the studio. Delayed keyboard, mouse connection fail. Highly annoying! We wrote a script to turn the BT device off and on … feels a little better, but still a lot of issues.

I'm able to pair my head phones to my 2019 MBP 16" however, Chrome cannot see an audio Input or Output device. I tried closing/reopening/on/off. This setup worked fine before upgrading.

I'm able to pair my head phone and everything works fine till I start some meeting (google meets / zoom / jitsi / etc). During the meetings, suddenly the bluetooth begins to fail till I got no sound being reproduced. Every time this happen I have to power off/on again. This start after I have upgraded to Monterey.

I'm sure there was some modifications in bluetooth component, because some commands as option+shift+click don't give me all the possibilities I had before as debug or factory reset.

I'm really having troubles here because my daily basis routine has several calls. Waiting a correction, workaround or anything else from apple =/

Bluetooth problem keeps on getting bigger,

After issues with my magic mouse and Jabra Bluetooth TWs, now my Logitech wireless keyboard is also having issues. some keys don't work while others don't work with (shift) key.

Since a couple of days I have. weird issue with my Apple Magic Mouse 2. Sometimes the mouse cursor just jumps a rather large distance, it is very weird.
