I have a voip account with fax/voicemail. In order to listen to my voice mails I need to perform the following instructions on an Apple:

"To set the nesessary permissions manually you have to create or modify
the ".java.policy" file in your home directory. Under Windows this is usually:
C:\Documents and Settings\<your username>\.java.policy

You can use any text editor (for example Notepad) to create or modify
this file. Place into this file the following text:

grant {
permission javax.sound.sampled.AudioPermission "record";
And then restart your browser."

How do I do this on an apple with OS X Leopard?
