@BadBiscuit @MT62 You can get an inexpensive external drive. People are having luck installing the same CD on both Windows and Mac. It doesn't work to install on the same OS but works to install on a different OS. And the new thing is if you first install from the CD you can't use the download (except for calling in).
See this FAQ. It says....you can download your software directly from TurboTax. But, keep in mind, you can't use both the CD and the download — you must use one or the other.
