Bluetooth fails to pair and/or connect iPhone with MacBook
My 13" M1 2020 MacBook Pro does not pair or connect to my iPhone 13 Pro Max. Popup says "not supported." All recommendations from Apple have been tried with no success. Other Bluetooth devices connect with both the Mac and the iPhone. Both devices appear on the respective lists, but there is no "connect" button.
MacBook Pro 13″, macOS 10.15
