Has anyone had problems / know a solution for getting Messages under 10.8 to video chat with iChat from 10.6? We have the kids chat with grandparents once a week, but after we upgraded to ML, we can't get video chat to work. We have the last of the MacBooks (2.26 GHz Core 2 Duo with 8GB RAM) running ML. They have a iMac 20in Core 2 Duo, but I'm not sure what the exact specs are. They are running Snow Lep, because they are tied to Quicken, and need Rosetta functionality, otherwise I would have upgraded them past 10.6. iChat worked fine between 10.6 and 10.7. Now that I have 10.8, and Messages replaced iChat, we are having problems. Text messages seemed to work fine, but the video refused to connect regardless of who originated the connection. Thanks for any suggestions.
