The OS X Messages Beta that was released to the wild yesterday will only work for Mountain Lion users once that version of OS X is released.
Arnold Kim, reporting for MacRumors:
Messages is the new iMessage-compatible version of iChat that will be included in OS X Mountain Lion. Apple also released a public beta version for OS X Lion users to try the app in the meanwhile.
Based on the text strings found in the App’s resources, it has been revealed that Messages will no longer be available for Lion users once the beta expires.
In the text strings Apple tells users to go to the Mac App Store to purchase Mountain Lion.
“Thank you for participating in the Messages Beta program. With the inclusion of Messages in OS X Mountain Lion, the Messages Beta program has ended.
“To continue using Messages, please visit the Mac App Store and purchase OS X Mountain Lion.”
Mountain Lion is expected to be released in late summer, and will be a paid upgrade.
