Whether you’re looking at the client (997MB), combo (1.2GB) or server (1GB) versions of this update, it’s pretty darned big and the likeliest reason for that are the eight “new” languages supported by OS X Lion. There’s also a fresh version of Safari (5.1.3) baked in, as well. What else is new? Step inside…

Although it isn’t available as a separate download as of this writing, MacNN reports that Security Update 2012-001 is in into OS X 10.7.3. Security issues in Address Book, Apache, CF Network, ColorSync, CoreAudio, CoreMedia, CoreText, CoreUI, curl, Data Security, dovecot, filecmds, Image IO, Internet Sharing, Libinfo, libresolve, libsecurity, OpenGL, numerous fixes to PHP and QuickTime, SquirrelMail, Subversion, Time Machine, Tomcat, WebDAV Sharing, Webmail and X11 have been addressed.

The company has also released Security Update 2012-001 for Snow Leopard and a server version is available, too.

As of this writing, Apple had yet to post release notes or a separate download link for Safari 5.1.3, which is exclusive to OS X Lion — no Snow Leopard version is available.

In related news, Safe Download Version reports that Apple updated Xprotect definitions on Thursday, January 19 to version 1023.

Apple has also issued detailed released notes, covering a range of items like newly supported Camera RAW in more cameras.

Update troubles? Try the combo version

A noticeable number of folks applying OS X 10.7.3 have popped up to say, according to OS X Daily, the update has resulted in a bizarre error screen littered with the letters “CUI, CUI, CUI, CUI…”

Happily there is a fairly simple work around — just apply the Combo Update.

That said, I always apply the Combo Update as I feel it delivers better performance and fewer after-the-fact issues…

What’s your take?
