I'm having the same issue, and still not resolved. I've downloaded multiple times, made sure my product key is in my intuit account, made sure my mac user account is admin ... nothing has worked. As soon as it tries to pull up the activation page, it gives me the not connected to internet error. All my previous versions of TurboTax work fine and download updates, so it seems to be something specific to this version and/or the activation process.
