Update went great on my install, however I know a lot of others on the bioware forums are having problem with the update and macsoft has put up a support page here: http://www.macsoftgames.com/products/nwn/support/MacSoft-NWN-Support.html Pretty quick on macsofts part.

Also there are instructions in the bioware forums on how to install the Shadows of Undrentide from the windows disc here: http://nwn.bioware.com/forums/viewtopic.html?topic=254140&forum=71
