The weekly release of new builds of the forthcoming OS X Mountain Lion 10.8.4 are continuing apace, with build 12E47 now available for testers -- again with no new changes or known issues, and again asking developers to focus testing efforts on the same areas as before: graphics, Safari and Wi-Fi performance. Earlier builds of 10.8.4 are known to be slightly improving battery life, addressing bugs with Wi-Fi stability and reconnection after waking from sleep, as well as fixing some remaining Nvidia card graphic glitches.
