On Leopard (and possibly earlier–I haven't checked), it appears that the string returned is actually a UUID created with the CFUUID functions concatenated with the process ID and the result of mach_absolute_time() so the result isn't a proper UUID. I'm not sure where the host name is coming from; it's possible that the CFUUID functions incorporate it somehow. -- Chris _______________________________________________ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
