I am using AutoCAD LT 2018 on a MAC. The one key shortcuts are not working. For instance when I hit "L" and enter nothing happens. I cannot draw a line. I have to type out "line" then enter. Also, it says it is "unable to find dictionary. Could not start speller." I already typed in "DCTMAIN" and "enu". That didn't fix anything. Do you think the whole program installed wrong? If, not how can I fix these things?
