Today Apple released version 10.7.3 of Mac OS X, fixing a few minor compatibility and stability issues in the operating system. If you've been having issues when using smart cards, authenticating with directory services, or you are running into Windows file sharing problems, this update is for you.
Mac OS X Lion version 10.7.3 also adds language support for Catalan, Croatian, Greek, Hebrew, Romanian, Slovak, Thai, and Ukrainian. There's nothing terribly exciting this time around, but you can update now by running Software Update on your Mac.
