Quick question, I'm new to macs.. So when you download a program, say Perian or whatever, after it finishes downloading it opens up to let you install, and you install it. On your desktop there's the "Perian" object that looks like what the HD looks like then there is also the .DMG file. Am I suppose to Drag the "perian icon" into my apps folder, and then DELETE the .DMG file? Cause that's what I'm hearing about this "mounting" stuff. Whenever I just delete the .DMG file, and empty my trash, when I go to my Apps folder and click on the "perian icon" it says that it can't be found, and that I can fix the Alias of it ...so I'm kinda confuse..am I suppose to make a new folder in the Apps folder and then drag the "perian icon" AND the .DMG file or what?
