Potential bluetooth connection malware I tried to disconnect and remove this device called '57-14-cf-5d-3c-62', and it doesn't work. I'm not really sure why, but I'm wondering if this is potential malware. If so, what is the best way to check and remove it?
You can't REMOVE it, as long as your Mac can hear the broadcast from this device, it will be listed there in the Preference Pane.
It's harmless, a BT device can't force a connection, you have to accept the pairing request.
