Apple earlier this week released revised "1.1" versions of Mac OS X 10.6.3 for both standard and server editions. The company has not specified what changes were made in the update, although such changes are typically minor and focus on addressing issues with the update that had gone undetected before launch rather than adding new features.
- Mac OS X v10.6.3 v1.1 Update (Combo) weighs in at 785.29 MB and as a combo update can be applied to any previous version of Mac OS X Snow Leopard.
- Mac OS X Server 10.6.3 v1.1 Update (Combo) weighs in at 897.32 MB and is similarly compatible with all earlier versions of Mac OS X Server Snow Leopard.
Mac OS X 10.6.3 was initially released in late March and addressed a number of issues with Snow Leopard.
Update: A support article on the release notes that the revised version is targeted at users who updated directly from the original Mac OS X 10.6 Snow Leopard to 10.6.3 using the combo updater. Users who updated from 10.6.1 or 10.6.2 are not required to apply this update.
The Supplemental Update is for any system that was updated from Mac OS X v10.6 using the Mac OS X Update Combined v10.6.3, build 10D573. It is not needed on systems that were updated from Mac OS X v10.6.1 or 10.6.2, and it is not needed on systems that were updated from Mac OS X v10.6 using the Mac OS X Update Combined v10.6.3, v1.1.
