Today Apple briefly posted a form for the OS X Mountain Lion Up-to-Date Program on its website before pulling it down again, accounts say. The program is designed to ensure that people who have bought a Mac since June 11th can upgrade to Mountain Lion for free, up to 30 days past Mountain Lion's release date. People who did manage to submit a form were sent two emails: one containing a password-locked redemption code, and a second email with the password in question. None of the redemption codes are believed to be working at the Mac App Store.
