Can a tour be downloaded to a Mac?

If you convert the tour to the full screen, that DOES have an offline version that works on a mac. The 2.0 tour uses the old offline tour and that is an exe file which is a Windows based file. So if you have parallels on a mac or bootcamp it will work, but that means you are using Windows on a Mac. So, switch to the full screen version if you need to download the tour to your MAC.
