Apple Releases OS X Mountain Lion Developer Preview 4 With Facebook Integration

Following today’s unveiling of new OS X Mountain Lion features at WWDC, Apple has seeded its fourth developer preview of the Mountain Lion beta to registered developers. The new preview can be downloaded for OS X server edition as well.

Although the new release itself contains few changes, Apple has included a separate installer that integrates Facebook into Mountain Lion. The company previewed this integration earlier today.

The small “OS X Facebook Developer Preview” .dmg file contains an installer for baking the social network right into the latest version of Mountain Lion. Once installed, you can sign into a Facebook account from System Preferences.

Partial release notes for the fourth developer preview of OS X Mountain Lion itself:
