Open dwg file from lisp script on mac

[Anonymous]

I have tried (vla-open (vla-get-documents (vlax-get-acad-object)) "filename") as many suggested but it does not work on my computer (mac with HighSierra). ERROR: no function definition: VLAX-GET-ACAD-OBJECT

Any ideas how i can get this done?

You are getting this error because MAC doesn't support any VL functions. 

Alternate option

(command "fileopen" opennewpathfile)

"Cannot run FILEOPEN if SDI mode cannot be established."
