After noticing an interesting environment variable Apple_PubSub_Socket_Render. I notice that it was referring directly to this "Render" file.
After doing a listing of "Render":
ls -lh Render
I see the following output:
srwx------ 1 user wheel 0B Mar 5 10:51 Render
As referenced in the ls manual page it notes this file as a "Socket Link"
What is a socket link?
