Just a reminder when Mountain Lion comes out tomorrow, the Facebook Integration feature will not be available till fall sometime this year. When it is release it will be available in an upcoming software update to Mountain Lion.
I’m not sure why it’s taking longer to add Facebook to the mix. It seemed to work ok while testing it in the Developer Previews. More than likely it is Apple and Facebook ironing out the deal.
This fall, OS X will be even more Facebook friendly. With built-in Facebook support, you can share what’s up with you right from the app you’re in. Post photos or links. Add comments and locations. Just sign in once, and you’re all set up. OS X adds your Facebook friends and their profile photos to Contacts so you can find them fast. When friends update their information on Facebook, it’s automatically updated on your Mac. Your Facebook notifications show up in Notification Center. And you can even update your status right from there.
