Hi epic quest,
Yes - all builds must be the same. There are a few very early versions (7.1.x) that can connect to 7.0.1120 - due to an overlook on our part. Feel free to use those, but kindly note that we can not help with unsupported setups experiencing bugs/stability issues.
That's hilarious because it's virtually impossible to tell easily what version of plugin is running on Mac OSX. This whole thing has been a nightmare for me. Like worst software experience of my entire life. Like running my arm over a cheese grater is more enjoyable then setting up and configuring VEP. No joke.
