omg.. how to do those things.. i'm new to mac and i can't even find icon for dvd drive. it should show in the finder right? dvd driver plays dvds so doesnt it mean that is fine and doesnt need drivers?
The installer does not launch automatically you need to open the disc and the launch the installer for Lightroom 3. If you do not see the disc on your desktop then I would recommend going under the Finder menu, next to the Apple, and selecting preferences. Once in the preferences window turn on the option to show CDs, DVDs, and iPods on your desktop.
