I guess I was a little unclear in my post. What I meant is that a lot of the diagnostic functionality available for PCs(memtest86 and Linux utils) can easily run on Intel Macs as well but given how relatively easy it would be, I don't see a native app that specifically advertises itself as a Mac hardware diagnostic tool unless I am missing something obvious. So, it seems like there must be no demand for a native app, but I am just surprised that nobody has attempted it. I haven't spent a huge amount of looking but then again I was trying to find a mainstream app not something obscure.
