Apple Seeds OS X 10.9.3 Mavericks Beta (Build 13D55) to Developers

Apple has seeded build 13D55 of OS X 10.9.3 Mavericks to developers, just over a week after the previous beta seed.

OS_X_19_9_3_build_13D55Apple is once again asking developers to concentrate on testing graphics and audio drivers, Safari, Mail, and iTunes USB syncing of contacts and calendars.

The beta is available to developers via the Update tab in the Mac App Store, and the Mac Developer Center. The beta should also soon be available to members of Apple’s recently reopened AppleSeed Program via the Mac App Store, but as yet, has not appeared there.
