I have used TT since 2003 and am getting very frustrated with the Mac OSX upgrades that are required each year. My 27" iMac is not capable of running anything higher than High Sierra.
My wife's 27" iMac can run Mohave and I do have a laptop that has Big Sur, but it is such a small screen to work on.
My question is why TT has this requirement. Is it the same for Windows? I can run Windows on my iMac.
It seems that Intuit should be able modify the software yo be more universal. Apple has many programs that run the same across many OSX versions. Microsoft Office seems to run across a variety of Mac OSX versions with no problems.
I plan to look for other software to do my taxes this year. Intuit needs to consult with Apple to figure this out or I think you will lose a lot of customers.
