That was my problem. I downloaded TT2020 Basic for Mac and it worked fine using Catalina. When I upgraded to Big Sur, TT2020 stopped working. I got "verifying everything is up to date" and then it quits. No error message or any other indication why.
I called customer service and she basically told me they were aware of the problem but did not have a timeline for when it would be fixed. She offered me a refund which was not what I wanted. I've been using TT for 20 years and I'm not going to just accept "it won't work, we can't fix it, find something else".
I DID have some options though. My Macbook Pro runs Parallels (virtual machine) which allows me to run Windows software fairly seamlessly. This is how I run MS Office. The Mac version of Office doesn't have MS Access so I NEED Windows.
So - she just put the Windows version of TT2020 in my download list and it works fine with Windows 10 on my Macbook. If TT2020 couldn't work with Windows 10 under Parallels, I was planning to run it on my Windows 10 Surface Pro. It's a full Windows OS - which I use to run MS Access while traveling.
