On macOS users may experience a non-functional mcgui, especially when having configured a local preferences file:

A respin of McStas v2.5 addressing this issue was uploaded to on October 10th, 2019.

If you experience the issue with an earlier download of McStas 2.5, the situation can be manually corrected by editing your local preferences (.mcstas/2.5/mccode_config.json) file using an editor so that the field "MCCODE_LIB_DIR" looks like this:

"MCCODE_LIB_DIR": "/Applications/"

As mentioned above, the newly uploaded v2.5 app has the issue fixed, so removing any old installation of McStas 2.5 and the local preferences file plus a reinstall should also fix the issue.
