Exactly a week after Apple released build 13D28 of OS X Mavericks 10.9.3 to developers, another one has been seeded today. The gap between these beta releases are decreasing, which probably means that a public OS X 10.9.3 release is just around the corner.
Just like the previous build 13D28, this new OS X 10.9.3 build 13D33 focuses on improvements to Graphics Drivers, Audio, Safari, iTunes contacts/calendar synchronization and Mail.
So far, we’ve seen support for a new native resolution that will enable newer Macs to output to 4K displays at a higher refresh rate of 60Hz. We’ve also seen improvements to Mail and iTunes USB sync, which has been causing issues to several users on OS X Mavericks. Hopefully these would be fixed when Apple finally releases OS X 10.9.3 to the public.
If you’re a developer, you can download the latest 13D33 build of OS X 10.9.3 from Apple’s Developer Portal or via Mac’s Software Update tool.
