It looks like SCDynamicStoreCopyComputerName is not prototyped correctly so the compiler assumes it returns an int. In what I assume is a 64-bit build this will lose the top 32 bits of the CFStringRef.
Are you #including <CoreServices/CoreServices.h>? Other than that I am compiling 32 bit so I don't know what else might be wrong with the setup of your project but at least now you have an idea of what to look for.

Here is my method:
+ (NSString *)
computerName
{
CFStringRef temp = SCDynamicStoreCopyComputerName (NULL, NULL);
NSString * name = [NSString stringWithString: temp];
NSLog (@"computer name = %@", name);
CFRelease (temp);
return name;
}
The line creating temp warns: initialization makes pointer from integer.
The line creating name warns: passing argument 1 of
StringwithString from incompatible pointer type
and fails with signal EXC_BAD_ACCESS
Thanks again,
Steve
