While Mac OS 10.2.8 is supposed to support the 106D, it may not, depending on the path you took to reach that version of the operating system. In addition, a small number of Pioneer 106D's are not compatible with Macs because their firmware is very slightly different from that in other examples of the same model. In your case, though, the firmware looks ok (the product id says DVD-RW while in unsupported models the id says DVD RW, without the hyphen).
