MacBook Pro Bluetooth Cutting Out

I have both a Bluetooth audio device (ReSound Phone Clip+) and a Bluetooth Magic Mouse connected to my MacBook Pro running Big Sur macOS 11.6.1. Periodically I have this problem, which will then fix itself for a while before recurring a few days later. What happens is that the BlueTooth becomes unreliable so that BlueTooth audio cuts in and out and the mouse's movements become jumpy.

I've just performed a test and discovered that the cursor doesn't react to movements of the mouse at the same time that the audio cuts out. After a short gap (usually < 1 sec.) when the audio cuts back in, the mouse again works. This means that it's the computer's BlueTooth that's failing, not just a connection to one or other of the devices.

I've Reset the BlueTooth Module. Any other suggestions?

Thanks in advance,

Though I don't have BT speakers, I've experienced the intermittent mouse behavior you describe a few times. My solution was to power off the magic mouse, wait a bit, then turn it back on. You might also consider charging it up completely to see if that changes the behavior.

Hello Erroll,

Thanks for that info and for choosing the Apple Support Communities. If we understand correctly, you are having Bluetooth issues with your Mac, as your Magic Mouse and Bluetooth audio device cut out at the same time unexpectedly. To help with this, check for sources of interference and depending on what year your Mac is from, run the built-in Apple Diagnostics or Apple Hardware Test to see if this will give more info about your situation:

Thanks for the reply, but the important thing to note is that the mouse and the audio fail at exactly the same time, so charging the mouse isn't going to fix the problem. I suggest that your problem, like mine is intermittent and just happens to fix itself while you're charging the mouse.

I now suspect that it's interference from some other wifi source.

Thanks again,

I don't disagree with your suspicion. My theory on device charge level is that a weaker BT signal could be more prone to interference and/or corruption. In my thinking, both devices failing at the same time doesn't preclude this. Please report back if you discover it to be another nearby BT or WiFi source.

Just another update to say this problem recurred a couple of days ago and even my Bluetooth keyboard disconnected and reconnected a few times. At the time, all my Bluetooth devices were over 95% charged.

It doesn't help much but, in the name of keeping this thread alive, I can report that I've had the problem this week and my Magic Mouse is close to fully charged.
