Alright I have had a few Macs, but I'm always learning. When I purchased Lion from the App Store last summer I was able to make a bootable usb drive. WEll I bought a new Macbook Pro today for her birthday. If Mountain Lion is already installed how or where can I find the installer file? Am I out of luck? Do I still have to buy Mountain Lion from the App Store to get the .dmg file? Thanks for all the help.
