Apple is strongly asking developers to focus on two major issues happening in Mavericks and that’s Graphics Drivers and Audio. So keep an eye out for those to issues – even though the list can go on and on.
I belive on the last Mavericks update 10.9.2 Apple was nice to fix the FaceTime Audio issue, the ability to block iMessage users on the Mac, and a fix for a critical SSL vulnerability that was spreading around. Come to think of it, it took Apple about two months before they made 10.9.2 public to be downloaded as final build. I guess, my question is what next for this build? How long will it take until it comes out public for download?
