Cannot Login Using 5.1.4 Mac OS Client

The first time opening the client it asks for server address, username, and password which I cannot type anything in any one of the spaces provided. So I cannot enter information to have the client login to start syncing.

Could you take a screenshot of the login dialog?

What the version of your OSX? I really can’t think of why this could happen.

OS X El Capitan 10.11.6
