Intuit TurboTax is refusing to install on MacOS 10.13 and says it requires Big Sur, but my iMac is from late-2012 and isn't on the compatibility list for Big Sur. Is this serious or is there an easy work-around?
iMac 21.5″, macOS 10.13
Turbotax Mac version (that installs and runs on your Mac) requires Mojave (10.14) or later. If you can install 10.14 on your Mac, you can use Turbotax on it. I think your iMac can handle up to 10.15.7.
The online version simply uses a browser and that can run with much older OS. But the online version can not handle some of the more complicated tax situations.

Sadly, if the applications required Big Sur and your Mac is too old to run Big Sur, you're stuck. :-(
Your only option is to locate an older version of TurboTax that will run on your Mac.
On the Intuit web site I see a list of requirements for multiple versions of macOS. There are different requirements for the online version and the downloadable version of TurboTax.
Good luck.
