Apple today seeded Mavericks 10.9.5 build 13F12 to developers, just over a week after seeding the first OS X 10.9.5 beta, build 13F7, and more than a month after releasing OS X 10.9.4 to the public.

10_9_5_13f12
The beta is available through the Software Update mechanism in the Mac App Store and through the Mac Developer Center.

It is unclear what improvements the 10.9.5 update will bring to Mavericks, but it is likely to include bug fixes and stability enhancements. Apple is asking developers to focus on USB, USB Smart Cards, Graphics, Safari, and Thunderbolt.

Along with working on improvements to Mavericks, Apple is also beta testing OS X Yosemite, which is due to be released in the fall. The last Mavericks update, 10.9.4, added several Wi-Fi fixes and improved wake from sleep reliability.

Looking forward for Mavericks 10.9.5, I am not going to 10.10 at least for 6 months, maybe more. A lot of Pro Apps like avid media composer, pro tools, Autodesk Maya among others works always better with an OS that is not brand new.
