OS X Mavericks (Desktop, MacBook)

Apple has seeded the first OS X 10.9.3 to registered Mac developers this evening. The release comes just a week after Apple released OS X 10.9.2 with fixes for SSL bug, Mail and FaceTime audio.

The new beta build is available to registered Mac developers through the Software Update tab in the Mac App Store, or as a full download via the Mac section of Apple’s online developer portal

There’s no word so far on what changes we should expect to see in the new version of Mavericks, but Apple has asked developers to specifically focus on graphic drivers and audio in today’s beta.

OS X 10.9.2, released last Tuesday, featured a number of bug fixes and other improvements. Today’s build is labeled as 13D12, and we’ll be sure to let you know if it includes anything new of note.

Update: enhancements have been discovered in the beta for 4K display users. Click here for more.

    When updating to 10.9.2 it still did not fix the mail fetching bug that everybody has had difficulty with. Is there a work around for this?

    • Carlos Gomes

      Yup, Sparrow.

      Airmail is by far the best and most robust email client on Mac. Sparrow used to be the king but Airmail took it to the next new level.

        Do you like Airmail a lot? It seems like there are even more bugs with this stupid update with mail. And $1.99 is a great price. I just need it to work with both my general and school email accounts.

        Airmail team pushes sometimes three updates a week. They are super active and respond to user requests. They have an official version in Mac store. And free beta version for anyone. I was beta testing their software since day one and never looked back

      • Jonathan Foell ™

        And automatic fetching for email is available too right?

      • Damian W

        Yes it is

      • Jonathan Foell ™

        Thank you very much! You’ve convinced me to upgrade to AirMail, especially knowing that it syncs iCloud contacts.

    I wish they would fix all the problems associated with running multiple displays, very frustrating. Wasn’t a problem before Mavericks.
