For years, AutoLISP ® has set the standard for customizing AutoCAD® on Windows®. AutoCAD for Mac also supports AutoLISP, but does not support many of the Visual LISP functions or the Microsoft ActiveX ® Automation interface. AutoCAD for Mac does not have an integrated development environment like AutoCAD on Windows does, so the creation and editing of LSP files must be done with text editor such as TextEdit.
