Get your taxes done using TurboTax

Actually I downloaded TT for Mac  and TT IT specialists (0n my computer remotely) could not get TT pages to scroll. Supervisor suggested a refund (which I accepted) after an hour of their work unsuccessfully trying to get TT to work with Mac Sierra 10.12.4 (newest upgrade). They seemed to have no hope it would ever work, i.e. that TT download is apparently incompatible with Sierra 10.12.4.  What other tax prep program has anyone found to be compatible with Mac Sierra 10.12.4?
