I've been buying and using TurboTax on my Mac for 23 years. This will be the first year that Intuit lost my business due to its inability to run on an older operating system. Please don't tell me to use the online version. If intuit can't create a piece of software for a computer, there's no way I'm trusting it's engineers with my security in the cloud. Please contact me when you have a piece of software I can use. Until then, good riddance.
