Hello,
I've found several examples of getting the computer Name but
some give warnings about making a pointer from an integer and
they all fail with signal EXC_BAD_ACCESS here

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.
Yes, your diagnosis holds water. I'm building
Are you #including CoreServices/CoreServices.h?
I wasn't. I added it. Were you wondering if it would make a difference?
Well, yes. Default return type is int. In fact I'm suprised you didn't get a
