Big Sur Bluetooth automatically connects

Hi,

In Big Sur my Macbook Pro 2015 retina automatically connects to unknown Bluetooth devices and I can't unpair them or block them.

For instance 53-3D-49-93-A5-3A is an unknown device, once this is connected I loose my mouse and keyboard inputs. This is very frustrating. There is no unpair option only the X. After I disconnect then again it automatically connects to another random Bluetooth device. I have no idea what this device is.

How can I set to not connect to unknown devices?

MacBook Pro 15″, macOS 11.0

Still struggling with this. 3 or 4 times a day at least, the computer connects to some unknown device and knocks out the BT connection on everything else. Incredibly frustrating.

Hi, If the address changes time to time, how do you explain which device is the culprit?

I'm facing exactly same issue.

To other ppl facing the issue: I seem to resolve this issue by removing devices from my iCloud account that are no longer active. I had several devices that I no longer own.

Could you try this: remove all your devices from your Apple ID, then add them back one by one.
