I think this conversation is for other thread 
But, about your point of view I think you’re are right in some way, but I think I’m right in another point of view. In my particular case, my profile is more extensive and I try to cover up the entire process of implementation of the product. By the way, I use a Virtualbox with Debian and frappe and erpnext installed from the scratch. I like your point of view, but I like too mine point of view.
As to the problem of the thread, you can see now it’s not a problem about the software on my Mac, I think is something about updating some data (DocTypes maybe) or a missing column in that table. I have no made modifications or tweaks to any table or DocType.
Anyway, thank you for share your thoughts.
