I’ve recently installed Adobe Connect version 9 in my test environment and any meeting rooms does not seem to work on my MAC Leopard(10.5). Meetings work just fine on higher versions or on Windows platforms.
With Adobe Connect 9, Adobe has released a new version of meeting addin, which has stopped support for Mac OS X 10.5 (Leopard). The reason behind this, is due to the fact, that Apple has deprecated the screen sharing APIs for OS 10.5.
If you have already installed Adobe’s new Connect 9 and are still running your MAC pc on an older version(10.5)/Leopard, go ahead and upgrade it to a higher version and you will be able to open your Connect 9 meeting rooms fine with the addin.
Note : All Leopard users will still be able to attend meetings from within the browser and will be able to use all basic functionalities, except from the functionalities provided by addin, like screen sharing.
