Uh, dude...it'll run just fine on a Mac. As a Mac user, you should know better than anyone that Safari is a Mac native browser...which, yep, is supported...
And the "Windows Service Pack" is nothing more than the bare essentials required for Windows operating systems to run things like flash and java, or any form of media really. Everything with Macs is hardcoded, so from the get-go they can perfectly run those plugins. It's nothing but the bare essentials for systems and browsers in general. So unless your machine is 15 years old, what's the problem? Honestly. As a Mac user, you should be ashamed for freaking out over that. Ashamed. Especially with "Safari" being listed up top and on the site.
