What are you trying to do? Are you trying to put the software on the Mac, or are you just wanting to put the tax files on the new computer? If you are trying to download the software, you will need help from customer support. The download software is specific to Windows or Mac, but if you paid for the Windows desktop software they will help you with the download for the new Mac's OS.
If you are talking about the tax files or the pdf's, those are not specific to Windows or Mac. You could put them on a flash drive and move them to the new Mac.
