It’s really simple. Safari on the Mac is easier to exploit. The things that Windows do to make it harder (for an exploit to work), Macs don’t do. Hacking into Macs is so much easier. You don’t have to jump through hoops and deal with all the anti-exploit mitigations you’d find in Windows.
It’s more about the operating system than the (target) program. Firefox on Mac is pretty easy too. The underlying OS doesn’t have anti-exploit stuff built into it.

On a scale of 1-10, how impressive was the Nils’ sweep of exploiting all three main browsers?
I was surprised. For IE 8, I’d give him a 9 out of 10. For Safari, maybe a 2. It’s just too easy to pop Safari. For Firefox on Windows, I give him a 10. That was the most impressive of the three. It’s really hard to exploit Firefox on Windows.
