Hello,  
Trying to install MNE-Python 1.9.0\_0 on an older Mac with Intel processor.  
On this Mac, the OS (Big Sur) was installed using the open-core patcher.  
The MNE installation succeeds, but when trying to run the MNE Prompt app, for example, error messages are displayed as if the MNE package does not exist - “No such file or directory”.  
Maybe someone has run into this and has a fix?
