Apple is yet to release the Gold Master of OS X 10.8.4 and many market observers believe that it will be rolled out sooner than later. A Gold Master or Golden Master indicates that this version of the software is intended to be the final version released to the public barring any last-minute issues.
Apple released the first beta of OS X 10.8.4 on April 1 and released eight different builds since then. The last build 12E55 was released on May 24, which asked developers to focus on windows file sharing. However, throughout the beta, Apple also asked users to focus on Wi-Fi, Graphics Drivers, and Safari. A beta version of the OS X 10.8.4 issued in April revealed support for the 802.11ac wireless protocol, which hints that future Macs may soon have speedy Wi-Fi technology.
OS X 10.8.4 will feature fixes for graphical glitches caused by some NVIDIA cards, better Microsoft Exchange compatibility, VoiceOver compatibility with text in PDF documents, a fix for FaceTime issues with non-US-style phone numbers and more.
A new version of Safari (6.0.5) is also expected to come along the software update.
The company's CEO, Tim Cook, have also already hinted that the upcoming WWDC event will focus more on software like the mobile operating system iOS 7 and the OS X 10.8.4.
