If you mean klot.lsp, then I've found it and tried on my side.
It loads with APPLOAD without errors (I close APPLOAD window with Cancel button). "Open" button allows to load lisp and close APPLOAD window in one step.
Furthermore, looks like this lisp works fine on Mac.

But I have to mention that when I was trying to load that lisp for the first time, AutoCAD sowed an alert:

If you want lisp file to be loaded, you need to select "Load" in this window.

Another lisp file - klotho11.lsp most likely will not work correctly in AutoCAD for Mac, as it uses dialog box(es) defined in accomplished DCL file, but AutoCAD for Mac doesn't support such dialog boxes (DCL files).
