I upgraded my macbook pro to Lion and then decided to buy a new Air and sell the Pro. How can I safely wipe everything off my pro and get Lion back to complete factory settings? Typically I would just use the recovery disc but we all know that's not possible anymore. I was reading about the built in recovery mode of Lion (command + R on boot up) - will this allow me to reinstall Lion and wipe everything? From the way I read, it may just reinstall Lion, leaving all my stuff/settings still here. Any help would be appreciated!
