For Mac users there are two versions of the game available, the Aspyr DVD version and the non-DVD version that was temporarily sold in the Apple Store.
This document describes what is needed for Macintosh users on a local area network (LAN) to play NWN2 multi-player with one another. For Windows users the Client Extension by Skywing () is a Windows executable NWN2 pre-launcher that replaces the broken GameSpy functionality so that servers can be accessed over the internet, allowing access to Persistent World servers. Some community solutions have been developed for Windows users, but there are no community solutions for Mac users. Both the Bioware account registration/authentication feature and the GameSpy functionality no longer work due to Bioware being hacked in 2012 and GameSpy dropping NWN2. Playing Neverwinter Nights 2 with friends over a network was never easy, but as the game has aged it has been getting harder, and for Macintosh users nearly impossible.
