Burn CD

Hi,

MacBook Air doesn't have internal Super Drive.

If you want to burn CD with MacBook Air, you need to get external USB Super Drive, and if your MacBook Air doesn't have USB port, you need to get USB-C to USB adapter.

FWIW, you can get any external burner as long as it is compatible; there are less costly options than the Apple branded superdrive.
