Nitrous,
I don't use a Mac but if you have the Mac TF up and running then everything else should be easy.
TAPs generally come as zipped files; you need to extract the .tap and .ini (if any) files and upload to the Toppy via Mac TF. Your Toppy should come standard with three directories: Recorded Services, MP3 & Program Files. Yuo can see these on your Toppy by pressing the Recorded Services button (above the yello & green button); use the << or >> button to toggle between the three. If there isn't an Auto Start sub directory within Program Files, you will need to create one if you want the TAPs to load upon booting the Toppy (which you will want for some). You can create folders on the Toppy by hitting the green button when the Program Files list is displayed, and you most likely could do it via Mac TF also. If you create the Auto Start folder, make sure it is named exactly the same as mentioned.
Any TAPs you load into the Program Files directory can be executed via the Recorded Services/MP3/Program Files button by selecting them and hitting OK.
