From an Informationweek article titled Isn't Tax Time Already Frustrating Enough?: Full story: http://www.informationweek.com/story/IWK20030227S0008 On their site, Intuit implies that SafeCast does not gather information to transmit to Intuit. They say "It does not examine, modify, or gather information about your computer, your computer's contents, or your activities or behavior, nor does it transmit any such information to Intuit." But on another page they admit how it works: "When you install your TurboTax CD-ROM for the first time, numeric codes are sent to Intuit in exchange for an Activation Code." If you read carefully, they are probably making correct claims, but this over-defensive explanation is just the kind of thing that worries people who care about their privacy and security. As a software developer, I understand that companies worry about protecting their software, but driving good customers away is bad business. I've already switched to TaxCut so I no longer use TurboTax for Macintosh (MacInTax), and Intuit isn't yet using a software security technique for their Macintosh products, but I think this article makes good points that Mac software developers and users should pay attention to.
