I'm also unable to activate on my MAC for the second year in a row. My solution last year was to run it on a windows 10 VM using VMware fusion. This year I had hopes to use my MAC OS but no luck. I took a ticket out and customer service closed the ticket as resolved in spite of the fact that I said it is NOT resolved. Now I am getting no response regarding the ticket. I am again successful installing and activating on my virtual windows machine but I'm not happy.
