Bluetooth connection, JBL Flip3 to Mac Pro I've read all the advise posted to connecting JBL Flip speaker to Mac Pro.
I'm not sure if this covers the new JBL Flip 3. Holding down the power button does not provide an alternating blue red light. The power button light stays white and Mac Pro does not detect the Flip 3. Any suggestions?

Also turned off all other BLT devises. Still no luck.
Try long-press on the bluetooth button on the Flip 3. That should make it discoverable in the Bluetooth preferences in the Mac.
