title: How do I find Bluetooth connections in Mac system logs
body: <p>I've lost my BT earphones, and am trying to determine the last time they were connected to my macbook, to narrow the time window and help the search. </p>
  
  <p>How can I learn this from system logs?</p>
  
  <p>I opened Console.app, and found numerous mentions of connections to BT devices, of the format:</p>
  
  <blockquote>
    <p>com.apple.message.domain: com.apple.bluetooth.connect
    com.apple.message.host: 05AC8290
    com.apple.message.process: blued
    com.apple.message.device: Unknown Name
    com.apple.message.uuid: 0x001F
    com.apple.message.direction: Outgoing
    com.apple.message.rssi: 127
    com.apple.message.pairing: LE
    com.apple.message.rate: LE
    com.apple.message.sco: LE
    SenderMachUUID: 557AF7B3-7829-380F-83D7-684B2004E540</p>
  </blockquote>
  
  <p>How do I determine which ones are connections to my BT earphones (not my smartphone)? I know the MAC addresses of both the devices that connect to this computer, but they don't seem to be mentioned in the logs.</p>
