Hello everyone,  
First timer here. I am a senior lecturer in macro at University of New England (Australia).

I am asking students to install Dynare 5.0 and Octave 6.4 to run some simulation.

My question is that a student is having problem with **Octave 6.4 & Dynare 5.0 on MacOS 11.6**. When he runs the Dynare code repagent0.mod (attached) he gets the following output:

Starting Dynare (version 5.0).  
Calling Dynare with arguments: none  
Starting preprocessing of the model file …  
Found 2 equation(s).  
Evaluating expressions…done  
Computing static model derivatives (order 1).  
Computing dynamic model derivatives (order 1).  
Processing outputs …  
done  
Preprocessing completed.

error: ‘num\_procs’ undefined near line 72, column 72  
error: called from  
default\_option\_values at line 72 column 63  
global\_initialization at line 136 column 14  
driver at line 24 column 1  
dynare at line 281 column 5

But there is no problem when I run it on my Windows version. This is quite problematic as I need him to be able to run Dynare and Octave to complete problem sets. I am not famililar with the Mac environment. Hoping someone out there in the big wide world has a solution for this.

Many thanks in advance.

Shawn

My understanding is that you need macOS 12 “Monterey” to run Dynare 5.0
