Hi. I have a Mac Mini (2011 2.5 GHz dual-core) and I am trying to install ML but it is not working. Downloaded from [removed]. I downloaded the .dmg file, double-clicked it. It opens to the install file, Library, Packages and System thingo. Then I open the install and install it to my Macintosh HD. I wait 15 and it says "Can't download additional components needed to install OS X." SOMEONE PLEASE HELP!
