OS X Lion hits 10.7.5 with most recent update, brings improved security with Gatekeeper
While the latest software for OS X Lion isn't nearly as exciting as a couple of other updates that Apple released today, Lion users will find a few worthwhile improvements within the new OS X 10.7.5 update. Most importantly, the latest software introduces Gatekeeper, a security feature from Mountain Lion that makes it more difficult to inadvertently install malicious software. The update also brings improved WiFi reliability for the iMac (late 2009 and newer) and squashes a bug that'd caused Launchpad icons to become rearranged. You'll find an even greater number of fixes / improvements after the break, and it's also worth a mention that even Snow Leopard users have received a bit of love today in the form of a security update. Want to prove you're a good cat owner? Go ahead and check for new updates right away.
