Apple has begun seeding developers with OS X 10.7.3 today, with a specific focus on how OS X handles iCloud storage and Documents in the Cloud. Apple is also asking developers to focus attention on iCal, Mail, and Address Book.
The update, which weighs in at 633MB, carries a build number of 11D16, and Apple currently lists no known issues with the beta. Also available is a pre-release version of OS X Lion Server 10.7.3 carrying the same build number and focus areas.
Paid Mac developers can download the update through the Mac Developer center, but be warned that you’ll be unable to downgrade if you apply the update.
Apple’s latest update to OS X Lion, 10.7.2, was released on October 12th, and introduced iCloud compatibility to OS X Lion.
