I have the latest driver package installed. After the OSX update, its a case of editing a single file to allow the newer OSX build version to run with the existing driver package; it will perform as it did before the update.
Once a newer driver version is released, you simply install that as normal and it will overwirte the edited file above and return everything back to the way it was, but obviosuly supporting the updated version of OSX.
You are free to do it either way; as described above or by temporarily using the beta driver.
I prefer the above method because although we are performing a minor 'hack' on one of the driver files, it means we get to use a more recent version of the driver and not an older beta version.
