To continue with my last post, I did some digging to see what the useragent on the new Intel Mac’s were. A while back, I was wondering what they would change it to. I now have the answer:
Mozilla/5.0 (Macintosh; U; Intel Mac OS X; en) AppleWebKit/417.9 (KHTML, like Gecko) Safari/417.8
For Firefox, it’s not quite decided (bug 323657).
