I know, but shouldn't there be a way around it? There is no app for Canadian Taxes. I tried it again and same problem. Would reloading OS x yosemite help?
Really baffling why you are having issues! I use OS 10.10.2, and it works fine. Of course, I only started up the program to the first screen, as I am in the US, and thus it did not make sense to proceed any further.
Also, I just did it again, on my Mac Mini, under OS 10.10.2, and once again, no issues, no control click, and I was able to start up the program. I even selected "Create a New Return", and got a page with some questions. But of course, I stopped, and quit the program.
Also, not sure what you mean by the question mark in your statement "The ? told me that I could hit control and click to download". Please explain.
Are you having any other issues with any other program, and especially with third party apps? And, are you using the latest version of Yosemite (10.10.2)?
Additionally, note that "StudioTax for the Mac is only available in English and does not support Quebec provincial returns.". Are you doing Quebec provincial returns (whatever those are)?
