picApple has seeded a new build (13D61) of the upcoming OS X 10.9.3 update to developers. The developer update comes just hours after Apple seeded a slightly newer build to its AppleCare team. 10.9.3 is expected to ship in the near future and features improved support for 4k monitors on newer MacBook pro models. The update also re-introduces the ability to sync contacts and calendar data to an iOS device from iTunes over a USB connection.

The update is accompanied by the very first seed of Safari 7.0.4. At the moment there are no details as to what’s new in the Safari update, aside from the typical performance updates and such. These updates don’t yet appear to be available for AppleSeed users.
