Runs super reliable under MacOS! I am very pleased with the read and write speed. The feel is very high quality and looks the part on the desk also very chic. The processed plastic affects quality and not cheap as in some competing products. The mechanism to introduce the discs is a drawer - sliding mechanism. A funding mechanism in which the disc is being drawn as the AirDrive would have been very nice. The mechanical way brings a lot of fine components with it, so you can better exercise a little sense. Nevertheless makes everything a coherent and also quite robust.
