this is probly a stupid question, but i'm a mac newbie from windows. anything i want to install comes in a dmg. which is the mac equivalent of an exe in windows right? what does ejecting the dmg do? and can't seem to figure out what i'm doing when i install a program and then try to delete the installer package. i end up deleting the app or i f@#! it up so it won't work. i feel really stupid asking this, so a little patience please. i was a real windows know it all but hated all the crashing and had to switch.
