Dynare MacOS -Unrecognized function or variable 'num_procs'

As outlined above, you did not install the arm64 version of Matlab. Thus, you cannot use the arm version of Dynare.

I tried [Dynare 6.3 (x86-64)] too. Still same error.

What is the error you are getting?

Now I got it thank you.
Now I get a different error and trying to look into it:

Error using print_info
Blanchard & Kahn conditions are not satisfied: indeterminacy.

Error in stoch_simul (line 119)
    print_info(info, options_.noprint, options_);

Error in NK_smallopen.driver (line 908)
[info, oo_, options_, M_] = stoch_simul(M_, options_, oo_, var_list_);

Error in dynare (line 308)
    evalin('base',[fname '.driver']);

That error is most often a timing error.
