Apple seeds OS X Mavericks 10.9.4 Build 13E9 to developers on Wednesday, May 28, 2014.
Apple is expected to preview the successor to OS X Mavericks at WWDC this coming June 2, 2014. Should Apple follow the current naming convention it would be called:
OS X 10.10
Pronunciation: OS Ten Ten point Ten
That’s a lot of tens.
What if it would be released on October 10, 2014?
