Apple has seeded OS X Mavericks Developer Preview 4 to developers. The latest build offers the usual bug fixes, but there's a couple of new small goodies tucked away inside as well. As 9to5Mac notes, so far four changes have been spotted. These include a new installation screen for OS X 10.9 Mavericks, a new Time Machine icon while performing backups, the ability to scroll through pages and windows in Mission Control, and finally, the ability to quickly post something to LinkedIn via notification Center.
OS X 10.9 Mavericks will ship this fall.
