Live Cycle Form - Get Operating System Information or Browser Info

[Daminu]

Hi,

We have a live cycle form with a submit button.

The form will be opened in a browser or using adobe reader or pro and we would like to display a message if the the OS is MAC when the submit button is clicked.

Is there any way to detect the OS and also detect the type of the browser (i.e. Safari, IE etc..)

Thanks
