For Mac OS X, we generally only provide the following updates for client versions of Mac OS X:
Mac OS X version and security updates (not firmware updates)
iTunes
Java security updates
QuickTime
Safari
The Safari 5.1.2 should be out by the end of today (as I already mentioned in your other thread). As for the rest, we don’t cover it by default. If you talk to support, they might be able to give you a reason why, or if there’s enough people requesting it, then we’ll add support for it.
