I recently decided to sell my MacBook Air. So I created a new account as Admin and deleted the old account, to which the laptop went black and beeped three times with a 2 second break. I then used recovery and formatted the disc... The big issue now is as the macbook was second hand I did not buy Lion I own Mountain Lion, Snow Leopard & Leopard and older. Recovery will only let an apple ID that own Lion install. I can no longer buy Lion in the app store!! Is there a way to boot the MB Air to use the disc on my other MB to install Snow Leopard or any other solutions?
