   10.9.3 Restores Local Contact and Calendar Sync, Improves 4K Support

   Josh Centers

   Apple has released [1]OS X Mavericks 10.9.3 Update, which brings a
   pixel-doubled Retina mode to external 4K displays and restores contact
   and calendar syncing between a Mac and iOS devices in iTunes. The
   Retina mode makes content much sharper, rather than just using all the
   pixels to create a truly huge desktop.

   You can grab the update via Software Update (461 MB) or from [3]Apple's
   Support Downloads site (461.7 MB). If you skipped any previous
   Mavericks updates, you can download a [4]combo update (947.2 MB) to
   upgrade directly from any earlier version of 10.9 to 10.9.3.

   The 10.9.3 update improves the reliability of a variety of networking
   activities, including IPsec VPN connections; network home directories;
   and copying, editing and inspecting file permissions on an SMB file
   server. Also enhanced is stability when installing configuration
   profiles and login speed for users in Active Directory groups. In
   addition, 10.9.3 resolves an issue that prevented installing PostScript
   Type 1 fonts in Font Book.

   On the security front, 10.9.3 includes a number of changes, but nothing
   new, just the same things that were released last month as part of
   '[5]Security Update 2014-002 (Mavericks, Mountain Lion, and Lion)' (22
   April 2014). Similarly, 10.9.3 includes Safari 7.0.3 in case you hadn't
   yet installed it (see '[6]Safari 7.0.3 and 6.1.3,' 3 April 2014).

   As always, we recommend holding off on installing 10.9.3 unless you're
   experiencing specific problems that it claims to resolve. Let others
   discover if it causes any unanticipated issues and upgrade in a few
   days if you don't see concerning reports online.
