Apple today seeded OS X Mavericks Developer Preview 4 to registered developers. The release comes exactly two weeks after the Preview 3 was rolled out. This year Apple seems to be following fortnightly seed schedules for its developer firmware. Registered developers who are already running the previous Preview can upgrade to the latest one through Mac App Store.


Among the changes that have been noticed, OS X Mavericks brings a new installation screen for OS X 10.9 Mavericks. The ability to quickly post something to LinkedIn connections from Notification Center is also onboard. Users are now able to scroll through pages and windows in Mission Control. A new Time Machine icon, displayed when making backups, has also been spotted. Developers are having a crack at this latest release, so it is likely that we’ll get to know about further changes that Developer Preview 4 brings over the next couple of days. OS X Mavericks was formally announced last month at the Worldwide Developers Conference. A concrete public release date has not yet been provided by Apple, but the company did say that Mavericks will be shipped to users this fall.
