I finally figured this one out.
I needed to update the EuControl Software. There are some strange bugs still in the software, but now I'm running v3.7 on OSX 10.13 with no problems. The red screen is gone and all the bugs I was having with the Eucon software crashing has stopped.
Here's the link to the download page for the EuControl software:
