That's great to hear! We can offer only a little help with running or troubleshooting LR on Mac (we haven't been testing with a real Mac environment yet), but perhaps you can also ask other Mac users here and see how they do it.
About the 14-day trial period, our system starts counting once you've installed LR trial, and not when you download the file. As for Internet connection, this is only required for certain features of Little Reader, such as the Latest News, Downloads, Progress Diary, etc. Otherwise, if you are looking to simply playing or personalizing lessons, then you can definitely use LR offline.
And yes, you will need to have a Flash Player installed too. There are a few more required software such as the Microsoft .NET Framework, but this is usually installed with Windows Vista and Windows 7 by default.
Should you need help with these, do let us know!
