Just downloaded Family Tree Maker for Mac 2. Having the same problem: Internet Connection Not Available. Running Maverick on my MacBook Air. No other app has a problem with internet connections. If you can download the app, you should be able to use it. I am using a WiFi connection. I did run fix permissions in Disk Utility. No joy. FTM for Mac was smart enough to tell me a new version was available. However the download of the update failed. Since FTM for Mac knew there was an update, then it seems that it did connect to the internet to discover that fact. I am quite disappointed that I spent $70 on an app that is totally useless. I hope this is fixed real soon or I am going to have to dispute the $70 charge with my credit card company. I have been a Mac user and developer since 1987 and a Linux user and developer since 1992. Just saying that I know how to troubleshoot. The problem is not on my side.
