No 2011 Mac runs Mac OS 9.
This guide should help you figure out what is needed:
Microsoft Teams Although Microsoft Teams is a free video conferencing app, it requires paid Office 365 commercial subscription, or a free or trial subscription of Microsoft Teams. Once you set up this app on your device, your professional life is in order. If you just got an Apple Watch, or are thinking about getting on, check out these apps will help keep you productive (hint! WebEx is one of them!) WebEx is one of them!). As a CCP member, make sure you are subscribed to all boards (discussions, documents, blogs, videos, and events so you always get the latest information from the program.
Note, the newest Safari it says will work, is version 6, whose version was only released for Mac OS X 10.7, and the last release which may run is for Mac OS X 10.8:
I would contact WebEx and ask them what's the maximum version of browser and plugin they have tried.
Go to Apple menu -> About This Mac to find your Mac OS X version. iOS does not run on Macs, it only runs on iPads, iPhones, and iPod Touch.
I've successfully used WebEx meetings as recently as having Mac OS X 10.9 installed last June.

Apple does not respond to this forum. This is just a user to user forum. The problem has to be addressed to Webex directly as their system requirements do not address the most recent browser versions Apple has. You may get this bug reported to http://bugreporter.apple.com/ after filing a free online developer account application at http://developer.apple.com/ however as WebEx is not an Apple product, I'm not hopeful this issue would be addressed. Apple uses that Developer link for all developers to address their issues, and it would be more fruitful for WebEx to determine what's missing in their code from Apple.
