Yea, I wrongly presumed TT wouldn't limit its licenses by OS.
With our Premium edition that allows 5 installations, I installed it on two of my PCs, and my kids were able to install on a combination of Mac and PC. All good. It was the state supplement that is limited to an OS. One purchased and download the NJ files for their Mac. I can't get the corresponding PC download without buying NJ again just to review their TT file because my PC can't open the file, even if I only wanted to see the Federal side.
This was supposed to be a simple parent lesson on how easy it is to use TT to file annual taxes or just to estimate and submit an extension. Turned out to involve some tears and a tutorial on what not to use. Ugh.
