Hello everyone,

I use MacBook Pro M1 with macOS 14.2.1.

When I run GRETNA in MATLAB, the following error message appears:

```julia
 Referenced from: <91A4AFCA-5C23-6A30-FB8C-A4C2CD09609E> /Users/mymatalbtoolbox/GRETNA-2.0.0_release/matlab_bgl/private/components_mex.mexmaci64
  Reason: tried: '/Users/mymatalbtoolbox/GRETNA-2.0.0_release/matlab_bgl/private/libmex.dylib' (no such file), '/usr/local/lib/libmex.dylib' (no such file), '/usr/lib/libmex.dylib' (no such file, not in dyld cache)

```

Is there any solution to fix this error?

Is this issue in any way related to Julia?

It’s indeed unrelated to Julia, but I really don’t know who to turn to for help.

If I have disturbed you, I apologize.

you’ll likely have better luck at [stackoverflow.com](http://stackoverflow.com). this forum is for Julia related questions.
