Yes, use your Mac for testing and development (creating courses), but do use a server for production purposes.
I know one tries to do with what one has in hand but my feeling, and I don't know much about Mac (except that I have never liked it, LOL), is that it would be easier and better if you were able to use another, more server-friendly, OS
I see that you already found how to change the URL...
