Guess what I just found out after again buying TurboTax from Costco and having installation issues for the second year in a row? If you install on a Mac and then want to install on a PC it won’t work. If your initial install is on a PC and then you want to subsequently install on a Mac, it won’t work. A phone call to Turbo Tax will be required. Apparently, the program cannot self adjust to working on two platforms although the TurboTax box does not say this. I actually tweeted to TurboTax about this issue.
