Hey, I just received my new MacBook Air 2012 yesterday and going through all the migration from my 2008 MacBook Pro. I already deinstalled Chess via Terminal and deactivated Dashboard to save Ram and SSD space and while doing that noticed that the MacBook Air (strangely) comes preinstalled with the DVD-Player Application. Is it safe to deinstall that via Terminal command as well or are some program files needed for other programs? Any suggestion? Thanks in advance!
