If you are experiencing issues with the Aclass properly propagating permissions to newly created files and folders, use this command from terminal:

chmod +a "X allow list,add_file,search,add_subdirectory,delete_child,readattr,writeattr,readextattr,writeextattr,readsecurity,file_inherit,directory_inherit" Y

Where:

X = the user name, or group name, or everyone

and

= directory path

You can verify if the command executed properly afteward by issuing this command:

ls -le Y

Where:

= directory path
