I'm in the same unfortunate boat as a lot of other people here. I got the e-mail in November saying that I'd need OS 10.6.8 this year, which I have, so I thought I would be fine. Then I purchase and download from Amazon and it turns out that it won't run on my machine because I only have an Intel Core Duo processor, which isn't 64-bit. I have lots of software on my machine that runs just fine. For many years, TurboTax has had very permissive system requirements. It's hard to see how all of a sudden it requires the latest and greatest to make tax calculations, when the latest version of MS Office, as just one example, doesn't require 64-bit.
Also, I'd be more forgiving if Intuit were a bit more friendly to Mac users. I'm still using Quicken 2007, which lacks many features of the Windows version.
Bob, I'd be curious to know what are all the great features over last year's product that you couldn't have offered in a 32-bit version.
Now to figure out how the heck to get a refund from Amazon for downloaded software ....
