Hi @Anonymous ,
Assuming you have AutoCAD LT and tried Terminal command from >>>this<<< post,
you can try these commands:
To change crosshair color:
defaults write ~/Library/Application\ Support/Autodesk/AutoCAD\ LT\ 2020\ Standalone/R23.1/local/HKCU_V1.plist "HKEY_CURRENT_USER.SOFTWARE.AUTODESK.AUTOCAD LT.PROFILES.<<UNNAMED PROFILE>>.DRAWING WINDOW.LAYOUTXHAIRPICKBOXETC" -int 8421504
To return back to original color:
defaults write ~/Library/Application\ Support/Autodesk/AutoCAD\ LT\ 2020\ Standalone/R23.1/local/HKCU_V1.plist "HKEY_CURRENT_USER.SOFTWARE.AUTODESK.AUTOCAD LT.PROFILES.<<UNNAMED PROFILE>>.DRAWING WINDOW.LAYOUTXHAIRPICKBOXETC" -int 0
You need to quit AutoCAD LT before executing these commands.
Autocad release number for 2020 version is R23.1, but not R23.0 as it was for 2019 version.
