Thanks I used pacifist and just copied the folder to the iTunes Plugin folder and it worked fine.

By the way what are these caches you talk of, I have next to no experience using Macs I'm a recent Windows convert and don't know my way around yet.

I've just downloaded and tried to install the Mac OS X version of the special holiday edition of white cap, and the installer is failing with an error indicating that iTunes must not be running during the install, however it is not running.

Any suggestions.
