Please provide any additional information below.

> I mentioned "with a different username" because the assistant will allow me to create a remote repository on the same target machine when I use my normal username. I think this is most likely because I have a ssh-key setup for the account on the remote machine. However I do not want to assume anything and send you down the wrong OSX rabbit hole. 

> After a little research it seems that OSX does not have a ssh-askpass
