Hi @michaelsirolli ,

If you have full (not LT) AutoCAD for Mac version, you can use these AutoLISP expressions to set grid lines color to white:

(setenv "2D Model grid axis lines color" "16777215")
(setenv "2D Model grid major lines color" "16777215")
(setenv "2D Model grid minor lines color" "16777215")

Copy - paste these lines to AutoCAD command prompt and hit Return.

Use REGENALL command to see the effect

To restore default colours use these AutoLISP expressions:

(setenv "2D Model grid axis lines color" "6114631")
(setenv "2D Model grid major lines color" "6901577")
(setenv "2D Model grid minor lines color" "4732722")
