Few days ago, Apple distributed the very first build of Mac OS X 10.6.5 to developers, dubbed 10H225. Today, the company seeded the second version of Mac OS X 10.6.5, which has been officially labeled as Build 10H529. Apple has apparently asked developers to once again focus their attention on Mail, Printing, 3D Graphics, QuickTime, and X Windows X11 subsystems. However, the company wants developers to evaluate Apple Filing Protocol (AFP) network file services instead of iCal this time.
The new Mac OS X 10.6.5 Build 10H529 also resolves the two previously known issues documented when enabling UI elements in Web Views and connecting to Exchange servers.
The new update is approximately 558MB in size.
