Ive successfully configured Saver and the Pandora client running TorEndPoints to run on a Mac.
The set up
IMac I7
Mac OSX 10.6.5
Parallels 6
Running Parallels I created a virtual machine running Windows 2003 Server configured to XP workstation mode.

Running Win03 as a virtual machine I downloaded the latest Xmas version of Saver.
Installing Saver was a bit ugly as the the installer appeared to freeze and I had to force quit the installer, however Saver was successfully installed.
I then reconfigured the proxy within Saver to the following settings.
Socks5
