When I did my last update of Leopard before the code was released with the last test build some weird stuff happened. One thing in particular was that the DVD drive was no longer visible in the Finder. This made a big problem because now the DVD couldn’t be ejected. Apple send me a final retail Leopard build a while ago but I hadn’t installed it but now I wanted to get it updated, but I couldn’t get the old DVD out. A bit of research revealed the answer which was to use the command line DRUTIL tool which worked a dream…fire up terminal and type this command
drutil tray eject
