Wednesday saw Apple seed a new build of Mavericks 10.9.5 to developers. The new seed, (build 13F24), comes just a little over a week after the release of the fourth seed, build 13F18. Apple is asking developers to focus on USB, USB Smart Cards, Graphics, Safari, Thunderbolt, and Gatekeeper.
Today’s beta seed is available to developers via the “Update” tab in the Mac App Store, and via download from the Mac Developer Center.
