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
Y = directory path
You can verify if the command executed properly afteward by issuing this command:
ls -le Y
Where:
Y = directory path
