Get your taxes done using TurboTax

Open the DMG after download. In THAT box where it shows to drag the app to applications folder, drag it right THERE to the applications folder within THAT dialogue box.  Dragging it to your dock folder or even in finder's application folder does NOT work.  Absolutely stupid of TTax to not specify this  when downloading/installing.  I've had Macs for over a decade and never encountered this issue.
