It was a bad design decision to assume you could ever write to this directory. What if your user isn't running as admin? The way to solve this issue is to use the BetterAuthorizationSample library: http://developer.apple.com/library/mac/#samplecode/BetterAuthorizationSample/Introduction/Intro.html#//apple_ref/doc/uid/DTS10004207-Intro-DontLinkElementID_2 Basically, you write a helper tool that runs as root, and comunicate with it what settings get what values. Then the helper tool, as root, saves the plist. Read and understand all the included txt files before you just dive into the code! _______________________________________________ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
