Hi @Anonymous,

I see that you are visiting as a new member to the AutoCAD for Mac forum. Welcome to the Autodesk Community!

 High Sierra is the latest OS that AutoCAD LT 206 is supported to work upon.  I do currently have it installed on Mojave and for the most part it works fine but I would not encourage doing this if you need the reliability and performance you expect with a truly supported application.
