Twitter SDK for cocoa (OSX)

I'm looking for a simple Twitter SDK for cocoa (OSX app). I've heard about MGTwitterEngine but it's been like 2 years since last commit so I'm wondering if you guys have another one to recommend :-)

MGTwitterEngine has not been updated because it is not needed anymore. OS X provides two frameworks that provide building blocks to create authenticated requests to social services.

• Accounts.framework gives you access to accounts configured by the user in Mountain Lion. See the ACAccountStore and ACAccount classes.
• Social.framework provides you with a SLRequest class to make authenticated requests on behalf of an ACAccount.
