macOS Sierra version 10.12.6 "Unsupported Operating System" message

[Anonymous]

As in the title, I'm running 10.12.6; the version before "Catalina".  I choose not to run Catalina because many of my licensed and owned programs will not run on Catalina; forcing me to RENT new software at annual renewing prices.  

I want to TRY AutoCAD LT to see if it will suit my needs.  Is there a way to upload it - or is there some other software version of AutoCAD that will run on my OS?

AutoCAD and LT2021 minimum requirements (you cannot have an older version) are:
Apple® macOS® Catalina v10.15
Apple macOS Mojave v10.14
Apple macOS High Sierra v10.13

You might try the automated system here to get a much older LT2019 or LT2018 version to test, but they will fall out of licensing by next spring https://ava.autodesk.com/

Tried for a while but I finally got High Sierra to load.  I didn't know Mojave was higher.  I've had Catalina and hated it.  Had to back down to Sierra.  Under Catalina a whole lot of my "Owned" software wouldn't work.  In order to continue things like MS Office I would have had to upgrade to the latest, which would have required a lease of the license, meaning a yearly charge.  Did NOT like being Shanghai'd.

Thank you for taking the time to reply.
