Works great with the Razer laptops though!
(BTW, you can't even buy any Mac with a decent GPU anymore, no matter what the form factor!)
In theory the nvidia out-of-os x drivers are for people using their cards on the pre trashcan Mac Pros. In practice they allow you to make yourself a decent hackintosh desktop. Or used to. Maybe the 1xxx cards don't work on the old Mac Pros, in which case i don't think nvidia can justify continuing putting out those drivers.
Who would this hurt? Apple. Very slowly though. Most people running hackintoshes are opinion leaders wrt to tech stuff, and when they switch to Linux or Windows, Apple will lose more mind share.
Okay, the drivers are labeled "for Quadro", but they support basically everything.
