Apple today released the second beta version of OS X Mavericks 10.9.5 for developers. Compilation 13F12 brings the same focus areas as the first (Safari, USB, USB Smart Cards and graphics) and, in addition, also asks for the Thunderbolt connection to be tested. This week the company also released a new compilation (13H5148) of the OS X Server 3.2 Developer Preview. Both updates are available through the built-in OS X update system (on the Mac App Store) or through the Apple developer portal.
