Had the identical problem and the sameTT response. The only way I got it to activate and work on my new iMac was to open a “new User” on my computer. I completed my taxes and they are now efiled just waiting for my refunds. I told TT support they need to read the postings in the Community. They do not know anything and I haven’t not heard anything from them for over a month since I submitted a problem ticket to them.
