Mac backup app. Macintosh users have heralded the arrival of Mac OS X as an advanced, robust operating system. The improved reliability of Mac OS X coupled with the scalable, secure MediaTone foundation is a reminder of WebEx’s dedication to providing a truly cross-platform experience.
It's not officially supported yet, they have been talking about 'coming soon' for quite a while - from the support thread 'he Mac client has been pushed back a little and is tracking to end of the first quarter of the 2011 calendar year' there are some configs that you could possibly use a jabber gateway to access webex connect, so in theory Adium or iChat would work. I have not been able to verify this due to my employer using an SSO gateway between the client and the server. Cisco now has web chat for webex connect - im.ciscowebex.com and is usable in most browsers including Safari. If your employer uses SSO (single sign on) then you may have to go through their web gateway and authentication process.
