Ensuring Profile Environment Variables Available to Intellij

Open IntelliJ via terminal: open "/Users/$(whoami)/Applications/JetBrains Toolbox/IntelliJ IDEA Ultimate.app"

This will ensure your .profile, .bashrc, and other profile settings that might be loading some default environment variables are available to your IDE. For macOS, you'd have to set in the environment.plist otherwise to ensure they are available to a normal application.
