Well they forgot to enable Journalling so they just have to turn it back on with this update. And after it runs the .dist file and makes sure you have the right machine, it runs this command:
/System/Library/Filesystems/hfs.fs/hfs.util -J /
You’ll find it in the postflight file. Besides that it installs a blank dummy file in /var/tmp, because otherwise a package will complain that it didn’t have anything to do!
Anyhoo, to check to see if you have Journalling installed, there are many ways, but here’s the Terminal way:
/System/Library/Filesystems/hfs.fs/hfs.util -I /
So just one file gets updated:
There are some telling strings about a JPEG2000 update in this file:
Warhol: that was the name of Quicktime when it was in development and apparently still around for nostalgia’s sake
Kakadu: This is a C++ framework for JPEG2000 handling, which is not just for stills, it can do motion too. I’ve always Vjed with MJPEG clips for quality’s sake.
QuickTime-616: The previous version of QuickTimeComponents.component contained QuickTime-579, and the Kakadu website mentions they are up to version six now, so it would seem this version number is related to Kakadu and not Quicktime? However I seem to remember QT Player Versions numbers and API’s don’t always sync…
However I can’t say exactly what else is in this binary file that improves compatibility with iLife. And I don’t think I’m gonna bust out otool and find out either. Pick up Amit Singh’s book for How-To’s on that :)
Another minimal blurb from Apple
About iMac Software Update 1.1
This update provides important bug fixes and is recommended for 20-inch and 24-inch iMac models with 2.0, 2.4, or 2.8GHz processors
OK so guess what the bug fixes are for?
That’s right more graphics stuff!
The Displays/Overrides file has all sorts of gamma values and RGB color points for the display to use. Then a couple kernel extensions for the video card, some plugins, drive bundle, and the Rosetta GLEngine. So an all round Universal patch fest for the drivers. Is AMD/ATI gettin’ to work or what!
However on second thought is the overides file with it’s color information a response to the 18-bit color reproduction issues some people have been talking about? Hmmmm….
