   Mac OS X 10.7.5 Lion

   Agen G. N. Schmitz

   Apple brings an added measure of security to Mac OS X Lion with the
   addition of Gatekeeper to the release of the 10.7.5 update. (If you've
   not been keeping up with Gatekeeper or other new features included in
   10.8 Mountain Lion, see Rich Mogull's primer from earlier this year '
   "[1]Gatekeeper Slams the Door on Mac Malware Epidemics," 16 February
   2012.) Note, however, that Gatekeeper isn't called out very visibly on
   the Security and Privacy preference pane in System Preferences. You'll
   find it in the General pane under "Allow applications downloaded from,"
   with "Mac App Store and identified developers" being the default
   setting. The update also resolves an issue where icons in Launchpad
   could get rearranged after a restart, improves Wi-Fi reliability for
   iMac models released in 2009 or later, fixes an issue using Spotlight
   to search an SMB server, and improves compatibility with Active
   Directory servers. It's available via Software Update (894.3 MB) or via
   direct download in two flavors ' a [2]Client version for those running
   10.7.4 (1.14 GB) and a [3]Client Combo version for those running
   previous versions of Lion (1.91 GB). (Free update)
