First time user, help please.

I've just downloaded pcsx2 for my mac and have gone through the installation steps but when I try to load my .iso image I get this error:

ZZogl: Disabling MRT depth writing
Offset 0xa247000 invalid. Legit SIGSEGV. Aborting.
pcsx2.sh: line 2: 1767 Segmentation fault: 11 ./pcsx2

Could anyone tell me what it means and how could I fix it?
