Finally, some relief from that nasty guest account bug is here. For many OS X users, this did not come a day too early. Other fixes include Spotlight not showing exchange contacts, four finger swipe gesture, VPN headaches among other items of interest that were fixed.
In my mind, I see this OS X update acting as a reminder that not all updates are created equal. Some of the bugs presented here are almost show stopping for some people, just annoying for others.
Yet in the end there is good news. Apple managed to get these things dealt with and that is just good news for everyone. It also means that Apple can once again focus their attention on coming up with features of the future vs cleaning up unfortunate bugs.
