- Facebook – From Apple : “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.” ** This feature isn’t available until Fall. **
- Twitter – From Apple : “OS X Mountain Lion is designed for tweeting. Sign in once and you’re all set up — and you don’t have to leave the app you’re in. Tweet links and photos directly from Safari, iPhoto, or Photo Booth with the new Tweet sheet. Add comments and locations. And when someone mentions you in a tweet or sends you a direct message, you’ll get a notification right then and there. You can tweet from Notification Center, too.”
