Following up on an earlier promise, Microsoft has released a delayed beta of Messenger for Mac 8. The update at last incorporates audio and video chat into Messenger for Mac, bringing the software closer to parity with its Windows counterpart. Cross-platform chats are supported.
In order to use the beta, people must sign in with a Windows Live ID. The app is a 22MB download, and requires an Intel Mac with Mac OS X 10.5, 2GB of RAM and a 128MB video card. Microsoft notes that the finished version of Messenger for Mac 8 is only due with the release of Office for Mac 2011, expected later this year.
