And, iTunes has gotten a nice bump, too, but look for that a little farther down the page. Yes, after nearly three months of testing, Apple pushed out a fresh Mavericks Update, OS X 10.9.3, which brings bugs fixes, network improvements and better 4K display support. What else? Step inside.

The easiest way to get OS X 10.9.3 is to open the Mac App Store app and click Updates. However, power users and system administrators have known for years that applying the the “combo” version of the updater yields better performance and stability.

So, bop on over to the Apple Support Downloads page and get the OS X Mavericks 10.9.3 Update Combo (download).

Features, fixes and tweaks in this modest Mavericks update, about 20MB or so, include the following:

— Improves 4K display support on Mac Pro (Late 2013) and MacBook Pro with 15-inch Retina Display (Late 2013)
— Adds the ability to sync contacts and calendars between a Mac and iOS device using a USB connection
— Improves the reliability of VPN connections using IPsec
— Resolves an issue that prevented Font Book from installing PostScript Type 1 fonts
— Improves reliability of copying, editing and inspecting permissions of files on an SMB file server
— Improves reliability of network home directories
— Improves stability when installing configuration profiles
— Improves login speed for users in Active Directory groups
— Includes Safari 7.0.3

And, for what it is worth, Apple has already begun brewing its next Mavericks update, OS X 10.9.4. Little to nothing is known about about this patch — stay tuned.

That done, iTunes 11.2 (download, also for Windows) is also available via the Mac App Store app’s Updates tab. New and notable stuff includes:

— Improved podcast browsing,including the ability to quickly find unplayed episodes, ability to save favorite episodes and automatically delete episodes after playing
— Resolves an issue where iTunes could become unresponsive when updating Genius and improves overall performance and stability. Podcasts for iOS 2.1 is recommended when syncing podcast episodes.
