After installing the new Messages app earlier this week the first thing I did was hit cmd-space-Mess to bring up the app via Launchbar. No joy. All I got was “New Mail Message”. I thought this was a bit odd but didn’t worry overmuch: I just went to Applications, found Messages in the list and launched from there.
Now, it seems, I am not alone. Dr. Drang of Leancrew (amongst many others) had exactly the same problem. Unlike me, he had to investigate further and he discovered that Messages is really iChat masquerading under the name of Messages. When you type cmd-space-chat (or whatever you have set up as the launchbar key) up pops Messages. It is all very strange.
