Looks like we should all brace for an Apple update; according to World of Mac’s sources, the Cupertino company is readying to release Mac OS X 10.6.3. The latest developer build of the update – 10D558 – went out recently, with the accompanying notes left unchanged; the sources “continue to insist” that it’s almost ready for a general release.

The developer version of the update apparently comes in at 710.5MB, and includes 64-bit logic performance tweaks, security changes, Exchange fixes in iCal and networking issues.
