Apple today released OS X 10.9.5, after approximately a month of testing and two months after the release of OS X 10.9.4.
OS X 10.9.5 will likely be the final update to Mavericks ahead of the release of OS X Yosemite, which is expected in October. OS X Yosemite brings several improvements to the operating system, including a revamped look and several new features that improve integration with iOS.
Update: Apple has also released Safari 7.1 for 10.9.5 users. Safari 7.1 adds DuckDuckGo as a built-in option in the search field, encrypts Yahoo searches from the search field, and improves website compatibility with both Reader and Autofill. DuckDuckGo is a search engine that does not track users.
