Blu-ray Support in Mac OS X 10.5.6?
The bulk of the information came from Kevin Rose who detailed a number of the changes accurately. Readers should find interesting that Rose also revealed some future details that have not yet materialized.
Specifically, Rose expects that Blu-ray support will finally be built into Mac OS X 10.5.6. Blu-ray is the next generation high definition video disc format that only recently "won" the format battle after major studios decisively chose it over HD-DVD. Apple has been a member of the Blu-Ray consortium for years but has not yet revealed their plans for Blu-ray support.
With the release of Mac OS X 10.5.5 earlier this week, Apple should begin work on Mac OS X 10.5.6. Built-in Blu-ray support into Mac OS X would open the door for Apple to finally incorporate Blu-ray drives into their Macs as well as Blu-ray support into their suite of iLife applications. The 10.5.6 update will not come before the rumored notebook revisions in October, but could conceivably be ready by Macworld San Francisco 2009.
