I've invited you to Splashtop.  Use that email to create your account.  Then 2 parts:

#1 On the computer you're remoting into (the office MacPro/iMac/desktop)

Install the Splashtop Streamer

#2 The computer you'll connect to the remote computer with (presumably a home laptop or similar)

Install Splashtop Business App

This is what you'll use to connect to the computer running Splashtop Streamer
