To paraphrase Harry Truman, ‘The only thing new in the world are the Apple secrets you do not know.’ Well, here is a small dent in that deficit courtesy of the publicly knowable sources about what’s inside OS X 10.8.4 12E55.
In addition to Wi-Fi, Graphics Drivers and Safari, Apple has asked developers to focus their testing on Windows File Sharing. Further, according to a MacRumors Forums post, the bullet pointed changes in OS X 10.8.4 include:
Features in OS X 10.8.4:
— Compatibility improvements when connecting to certain enterprise Wi-Fi networks
— Microsoft Exchange compatibility improvements in Calendar
— A fix for an issue that prevented FaceTime calls to non-U.S. phone numbers
— A fix for an issue that may prevent scheduled sleep after using Boot Camp
— Improved VoiceOver compatibility with text in PDF documents
— Includes Safari 6.0.5
Known scuttlebutt also includes the existence of 802.11ac (a.k.a. gigabit wifi) references in OS X 10.8.4, as well as Geforce GTX TITAN drivers — neither of which are guarantied to be part of the final product.
