Apple updates OS X to 1085 WiFi,

Apple has just rolled out version 10.8.5 of OS X in order to remedy a number of recent issues with Mountain Lion. The update packs fixes for WiFi file transfers over 802.11ac, message display issues in Mail and unwanted screen saver appearances, along with the usual less-specific tweaks. If you haven't already seen the App Store notification in your Dock, a quick trip to that repository should reveal the fix after a required restart.
