I also could not activate TurboTax 2023 and 2024 on my Apple computer. I noticed a fix from another macOS customer and he suggested that he had to open a New User account on his computer and then was able to activate TurboTax. This also worked for me with absolutely no help from TurboTax. I spoke with customer Service twice and they were totally unaware of this problem with both Windows and Apple customers. I even put in a problem Complaint and to this day have not received any response from TurboTax. Also my 2023 TurboTax had the same problem when I tried to open it to identity my 2023 tax return because 2024 could not locate my prior year tax return. Now I have to input all data manually in order to prepare the 2024 tax return. There is no customer service at TurboTax. Good luck on fixing your problems.
