I'm having problems with my Mac Mini's internal DVD drive. I have a late 2009 Mac Mini running OS 10.6.8 and the DVD drive isn't reading some discs. I used a DVD cleaning disc a few months ago and it started working again but now it's not. I even tried wrapping an eyeglass cloth around a credit card and inserting it into the slot to clean it but it didn't help much. I've read some good things about this one in the link below from LG but now I see it says you need OS 10.7.5. http://www.lg.com/us/burners-drives/lg-GP65NB60-external-dvd-rewriter I also read somewhere that if a Mac already has an internal DVD drive then an Apple Superdrive may not work. Does anyone know if this LG DVD drive will work with my setup? Is there another alternative that won't cost too much?
