First Beta of OS X Lion 10.7.3 Seeded to Mac Developers
Apple has seeded the first release of Mac OS X 10.7.3 to developers, the build is 11D16 and focuses on iCloud document storage, in addition to changes to Address Book, iCal, and Mail.
The update weighs in at 633MB and is downloadable through the Mac Developer Center to registered devs for both OS X Lion Client and Server. Apple recommends that users install the update only on Macs they don’t mind erasing, warning that downgrading back to the stable 10.7.2 build is impossible (although this is usually easy through Time Machine backups).
We’re hoping the vague “iCloud document storage” changes are to officially include native iCloud file syncing in Mac OS X, although there is no word on that yet. If you’re interested in reading the official release notes, you can check them out on 9to5mac.
For reference, Mac OS X 10.7.2 was released on October 12, 2011 and included iCloud support in addition to bringing a variety of fixes and adjustments to Lion.
