Thank you!
Also, about the issue Travis mentioned, I figured that you only need to close and reopen Vensim. Here's the test:

I can confirm it is working for me too. I had to `chmod +x` the scripts in the zip file above. I also changed the group ownership, but I think the +x was the key issue.

Glad we figured this out and it wasn't the certificate signing issue!

On Vensim DSS 10.2.1 (MC), the compile error randomly happens (I have a hunch that it happens if it wants to recompile the model after some equations have changed) and the only workaround I've found so far is to close and reopen Vensim. I hope there should be an easy fix for this in the source code. Thank you so much!

Can you summarise the problem again, this post is over a year old.

Vensim works fine the first time a model is compiled. But if the model is changed and it's going to be compiled again, you'll get the error “Failed to compile the model (does not exist).” However, upon closing and reopening Vensim, it works without any error. 

ok, I'll test. Hopefully it's something very simple like a permissions issue.

This is working fine for me.

Are you using a file sync application at all? Maybe the .c file that Vensim creates is being marked as in use?

Interesting. Not really. It could be caused by some security software that my institution installs on macOS. I'll check more and let you know. Thank you!
