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
