Apple has now begun reissuing OS X Mountain Lion redemption codes to customers eligible for its free up-to-date program. These codes replace those issued to customers earlier today, which had already been redeemed, according to the Mac App Store.
Free to eligible customers, but you’ll have to wait for it.
Several readers have contacted Cult of Mac to report that Apple is issuing them used redemption codes for OS X Mountain Lion through the free up-to-date program. The Cupertino company’s customer support line has acknowledged the issue, and promises a fix is coming later today.
