Macbook Air bluetooth fails to pair or connect
Macbook Air 2015 Bluetooth will not connect with several already-paired devices that it's connected with in the past. Also Bluetooth speaker not previously paired when I try to pair it does not appear in the device list in Bluetooth preferences. Occasionally Bluetooth will connect with a device but then not play sound. (I have tested all these devices with Android and Windows and each pairs, connects and plays sound easily.).
MacBook Air 13″, macOS 12.7
