Kiwi Ian, I escalated my issue within tech support and a more senior tech was able to help me. He had me create a separate user with admin privileges on my mac. I downloaded the software under that user. I copied my TT21 files onto a flash drive and brought them into TT under the new user. So far that has worked. Tech said this is a workaround to a known issue. It's extremely frustrating but this solution is better for me than redoing my taxes using the Web version.
