I purchased Lion from the App Store, installed it, etc. Now that I'm selling my Mac Mini, I'd like to keep Lion on there since: 1) I have no need for the purchase anymore since any new mac buys will have it preinstalled, and 2) it'll make my mac mini for sale that much more desirable of a buy.
What I've done so far is boot into Recovery Console (maybe I have the name wrong? -- Cmd+R mode during booting), and I've done the Secure Formatting of the hard disk, and when I go to reinstall Lion, it wants me to put my Apple ID in to download Lion.
Unfortunately, I didn't save the dmg file when I downloaded Lion, and I have been unable to find it on the computer (i.e. to create an installer disk as I've read about online). I don't even know if this bypasses the need for an Apple ID.
Any suggestions is appreciated.
