AppleCare employees today received a new build of the upcoming OS X Mavericks 10.9.3, according to sources. The build number is 13D62, which indicates a jump from the previous AppleCare seed of 13D59. The current beta for developers is 13D55…

We reported on the release notes of improved 4K display support and syncing functionality last week, and today’s build lacks the commonplace “PRE-RELEASE” labeling, and this indicates that 10.9.3’s release is imminent. Perhaps it will even be released today or later this week. We reported a few days ago that 10.9.4 has already hit an alpha stage within Apple. We’ll keep updating as we learn more.
