Hi @joW8BBH ,

Have you tried this option?

If you want to get back the dialog box shown above you can use "Reset hidden messages" on Application tab of AutoCAD Preferences.
If this doesn't help, you can try to quit AutoCAD, trash Profile.aws file inside
"~/Library/Application Support/Autodesk/Autocad LT 2025 Standalone/R24.1/roaming/Support"
folder, then relaunch AutoCAD.
Not sure about Autocad LT 2025 Standalone, but you can check the name yourself - it should contain Autocad LT 2025
~/Library - means Library folder inside your Home folder and it is hidden by default.
