   OS X 10.9.4 Includes Wi-Fi, Wake from Sleep Fixes

   Josh Centers

   Apple has released [1]OS X 10.9.4 Mavericks. The 283 MB update is
   available via Software Update, and should be available soon from
   [2]Apple's Support Downloads Web site.

   Highlights of the update include a fix for a bug that prevented some
   Macs from automatically connecting to Wi-Fi networks (for other
   suggestions, see Alicia Katz Pollock's '[3]How to Solve Wi-Fi
   Connectivity Problems,' 7 February 2014), improved reliability of wake
   from sleep, and the inclusion of Safari 7.0.5, which features a number
   of [4]security fixes.

   Bundled into 10.9.4 are the usual slew of [5]security improvements,
   including an update to the certificate trust policy, a fix for
   sandboxed apps being able to circumvent restrictions, and elimination
   of an issue that could allow local users to see Apple ID credentials in
   iBooks logs. Other fixes eliminate problems related to the Intel
   graphics drivers, issues that could cause unexpected restarts, bugs
   that allowed arbitrary code execution, and a number of vulnerabilities
   in Unix system utilities.
