Mac connects to an unknown Bluetooth device that is not on the device list
Hi, I have a 2020 13" MacBook Pro that I bought back in May 2020. Recently, I notice the Bluetooth menu on the menu bar indicating that it is connecting to a device, I do have a Bluetooth headphone, but I never connected it to my Mac, nor anything else.
When I open the Bluetooth pane on the menu bar, there were no devices listed and yet, the Mac is connecting to something. Then I went into Bluetooth Preferences and there were no devices there as well.
It happened for a few days already and I tried to resolve it by restarting my laptop quite a few times, but it still said it is connected to something. Has anybody experiencing the same thing? Is this just a bug or am I being hacked?
I appreciate for any help I can get.
