Setup Facebook Chat with Messages in OS X Mountain Lion
Apple recently announced OS X Mountain Lion and is expected to be released this summer 2012. If you're adventurous enough, you can download and try out the developer beta release of OS X Mountain Lion.
For the remaining mere mortals - you and me - you can try out Messages Beta which will be part of the new upcoming OS X Mountain Lion.
You can use your iCloud ID to sign-in to Messages and start using it right away. The other supported services are AIM, Google Talk, Yahoo! and Jabber Protocol.
