One week after seeding the last OS X 10.9.4 Mavericks beta, Apple on Thursday issued to developers a new build of the upcoming maintenance update, with the latest version coming with minor bug fixes and minor tweaks.
The latest OS X 10.9.4 Mavericks build 13E25 continues Apple’s usual one-week release interval and follows build 13E19 seeded last week.
Thursday’s release focuses on the same areas, including Graphics Drivers, Safari, Bluetooth, Audio Drivers, Finder and the App Store.
The initial seed was issued at the end of May following the public release of OS X 10.9.3. Along with developers, Apple announced a limited number of consumers can also take part in testing out betas seeds.

OS X 10.9.3 is now available to download through the Mac App Store. Apple says the update is recommended for all Mac users, and that it improves the stability, compatibility and security of the operating system.

Other additions and changes in OS X 10.9.3 are:

The ability to sync contacts and calendars between a Mac and an iOS device using a USB connection
Improved reliability of VPN connections using IPsec
Safari 7.0.3 is also included

While the update introduces a “Retina” output mode for the late 2013 15-inch MacBook Pro, it does not grant the same ability to the 13-inch model. Apple’s current Thunderbolt Display does not come with a 4K resolution, meaning the support is only available for third-party monitors.

OS X 10.9.3 had a particularly long beta period, with nine pre-release builds being provided to developers before Thursday’s official launch to the public.

The launch of OS X 10.9.3 comes less than a month after Apple opened up its beta seed program to all users in exchange for “quality and usability feedback.” The program allows anyone, not just Mac developers, to test pre-release versions of OS X.

Yes, new week, new OSX beta. Apple today seeded build 13D61 of OS X 10.9.3 to developers, just over a week after releasing the ninth OS X beta, build 13D55, and nearly two months after the first 10.9.3 beta. This seed is accompanied by Safari 7.0.4.

The beta is available through the Software Update mechanism in the Mac App Store as well as through the Mac Dev Center.

Apple continues to ask developers to focus on Graphics Drivers, Audio, Mail, Contacts and Calendar sync over USB in iTunes, and Safari. As was discovered with the first beta, 10.9.3 adds new support for 4K displays, offering “Retina” resolutions that improve readability along with support for 60Hz output from the Retina MacBook Pro.

OS X 10.9.3 is likely nearing completion, as AppleCare employees were today seeded 10.9.3 build 13D62, one build later than what developers are receiving. A public launch could come as soon as this week.

Apple seeded build 13D55 of OS X 10.9.3 to developers, just over a week after releasing the eighth OS X beta, build 13D45a, and nearly two months after the first 10.9.3 beta.

The beta is available through the Software Update mechanism in the Mac App Store as well as through the Mac Dev Center.
