Apple has seeded a new Mac OS X 10.7.3 build to developers, replacing a version that it released just last week.

The focus areas of Mac OS X 10.7.3 Build 11D46 are iCloud document storage, Spotlight, Safari, Mail, iCal and Address Book features, reports Apple Insider.

It's a 1GB file and it includes support for several more languages - Catalan, Croatian, Greek, Hebrew, Romanian, Slovak, Thai and Ukrainian - and there are drivers for AMD's 'Tahiti' graphics cards included.

The new build also fixes issues when using smart cards to log in to OS X, issues authenticating with directory services and compatibility issues with Windows file sharing.

It's the sixth developer build of OS X 10.7.3 to bereleased. The first was issued in November last year and all have focused on iCloud integration into the operating system.
