Get your taxes done using TurboTax

@Constantins   You can only disable the Updates in the Windows version.  As soon as I install the Windows Desktop program and it updates the first time then I go to Online-Updater Preferences and select Ask me before getting updates.

In the Mac program updates are automatic when you open the program.  I think you can first turn off your internet or wifi so it won't check.
