Hi I have a new macbook pro with the 9400m geforce graphics in and wondering if updates for this are automatic? I ask because I have a regular desktop pc with a gaming nvidia card in and it is my responsibilty to update those drivers when new drivers are released. So, do I need to update my macbook drivers? I assume its an nvidia being a 9400m but when i look at the nvidia website and select the card there are no mac drivers, only windows drivers. So what's the deal then? Is it automatic or not?
