macOS 13.5 Ventura (and above) introduces automatic connection to WIDI devices after the first time pairing.
After confirming the pairing when you first connect between your macOS operating system and the WIDI device, it will automatically reconnect every time you start your WIDI device or Bluetooth on your macOS operating system.
This is a great feature because from now on, you won’t have to connect manually every time. That said, it may cause confusion for those who want to reconfigure their setup without macOS or work with multiple WIDI devices.
To avoid this, you can disable Bluetooth on macOS or remove all (unwanted) WIDI devices from your general list of Bluetooth devices via the “Forget this Device” option in the Bluetooth menu of macOS.
This will avoid the automatic connection with your (unlisted) WIDI devices and you will have to confirm a pairing manually first when you want to connect again to the built-in Bluetooth of macOS operating systems.
