When have attempted to install 4.0.3 client on Mac OS, however, we are seeing that the Group Policy Client Management License MCX component is missing as shown in the documentation.
Product Documentation Defects: 25101 and 25100 were added in for these issues (one for documentation and the other for vastool license).
In 4.0.3 it was decided to remove the need for an MCX license; the only license needed is the server license. However the documentation still shows the information about the license. Also the vastool license command still shows the information.
