I have to say I am very frustrated. I have always gotten the TurboTax CD for the last 10 years. This year, all you get with the box but it is a download. My partner and I work on 2 different systems I work on Windows and he works on Mac. On the box it states Windows and Mac. WHICH is a Lie! When I called to get the download for my PC. I was informed it is Windows OR Mac. Since he downloaded first for his Mac, I can not get a download for my Windows. TurboTax is falsely advertising Windows and Mac download when in reality it is either one OR the other. The packaging still states that you can do 5 federal e-files. But I guess you have to do them all on one system. Really feeling like this is false advertising.
The purchase of the CD/download should provide you with the ability to download to either Mac or Windows. But the downloads are specific to Mac or Windows. If you get a customer service rep who knows what they are doing, you should be able to get the download for either one. You are allowed to download to any five computers you own---and it does not matter if they are all Mac or all Windows.
