To answer this, no I don't think so. First off, a MacBook (non-Pro, though I'm not sure which model they used, didn't see the video) has no slot at all. A MacBook Pro has the ExpressCard slot. I doubt there's a Wi-Fi card for it, but there will be some other things for it soon if not already.

Apparently the test hack was done with a third party USB-based wireless adapter.

Exactly what's going on here and if it's significant still doesn't seem clear to me. I've read that certain prefs are changed from the defaults, but I haven't seen which ones. I don't know if it affects other Mac models. I don't know what kind of access is gotten via this exploit. And I don't know what we're supposed to do as a workaround. And we don't even clearly know it works with the internal wireless card. In other words, we know very little useful about combating the exploit, just that there is one, and it used a third-party access point and required non-default prefs of some kind. I think the criticism of the reporter is valid, given that he focused only on the sensational parts of it without any note to the practicalities for actual users.
