Yes, I've used APPLOAD. When I'm asked to pick the Lisp file, I choose it and then click on "load". It then says it successfully loaded. But I need to close that window (picture below) to get back to Autocad. There I have the choice between "open" and "cancel". Whatever I choose - the command box then says APPLOAD

failed.

I don't know what this lisp was created on but I wanted to try it on Windows next week. Maybe it works there then it's because I use Mac. 

Is there any way I can transfer it to Mac?
