Apple Mac OS X 10.6 Snow Leopard builds on a decade of Mac OS X innovation and success with hundreds of refinements, new core technologies and out of the box support for Microsoft Exchange.
To create Snow Leopard, Apple engineers refined 90 percent of the more than 1,000 projects that make up Mac OS X. Users will notice refinements including a more responsive Finder; Mail that loads messages up to twice as fast; Time Machine with an up to 80 percent faster initial backup; a Dock with Expose integration; QuickTime X with a redesigned player that allows users to easily view,

To create Snow Leopard, Apple engineers refined 90 percent of the more than 1,000 projects that make up Mac OS X. Users will notice refinements including a more responsive Finder; Mail that loads messages up to twice as fast; Time Machine with an up to 80 percent faster initial backup; a Dock with Expose integration; QuickTime X with a redesigned player that allows users to easily view, record, trim and share video; and a 64-bit version of Safari 4 that is up to 50 percent faster and resistant to crashes caused by plug-ins.
Snow Leopard is half the size of the previous version and frees up to 7GB of drive space once installed. For the first time, system applications including Finder, Mail, iCal, iChat and Safari are 64-bit and Snow Leopards support for 64-bit processors makes use of large amounts of RAM, increases performance and improves security while remaining compatible with 32-bit applications.
Grand Central Dispatch (GCD) provides a revolutionary new way for software developers to write applications that take advantage of multicore processors. OpenCL, a C-based open standard, allows developers to tap the incredible power of the graphics processing unit for tasks that go beyond graphics.

I *think* what this update is is actually 10.6.8 with the above "Supplemental Update" already rolled into it, and as a combo updater, can update an existing 10.6.8 installation the same as just installing the "Supplemental Update" can.
I hope my frustration with version numbering is more appropriate now... :) Not only are there two versions of 10.6.8, there are apparently two differently named updates to end up with the new version. (Is it "10.6.8 version 1.1?" Is it "10.6.8 with Supplemental Update?" Seems like it's both!)

Replacing the mach_kernel file with the 10.6.7 version from my emergency back-up restored everything to normal.
I experienced the same issue after applying the MBP Software Update 1.4 which installed a newer version of the mach kernel, turned out the new Combo updater has the same newer version of that file. You need to make the mach-kernel (to be found at your main volumes root level) visible first before being able to replace it.

If you're having lots of weird bugs, I highly suggest doing a fresh system install, running software update until everything is curent, and then migrating your user files back from your time machine.

It's stupidly confusing. Call it 10.6.9 like the original poster suggested. Or if you're scared to bump it to 10.6.9 if it's "too minor," then use 10.6.8.1 or 10.6.8a or something at least halfway-sane like that.

Make it a named update of some other sort rather than a version (with revision, no less!) of a version, or call it something that makes sense... Using overly complicated version numbers makes them much less useful.

1) UnderCover v4.5. This problem has been eliminated now; the developer sent me an update within 18 hours to correct the problem. Thank you, Peter!
2) iTunes v10.3.1. This problem persists. I have no idea why iTunes needs to constantly know my location, but turning on iTunes while my AirPort is active results in an endless stream of locationd access attempts. I've included this in Troubleshooting on the iTunes page (http://www.macupdate.com/app/mac/5661/apple-itunes)

This update is really dangerous ! Don't apply it !

See my post below.
The mach_kernel resides at root level as an invisible file.
Boot from your emergency back-up, then
locate it with Path Finder or another suitable application, make it visible. Find the older machkernel by browsing through the 10.6.7 Combo Updater using the demo version of Pacifist (look it up here on MU), extract it to your Desktop (remember to make it visible first, I think it is possible from within Pacifist). Alternatively, use Path Finder and drag a copy from your working back-up to your Desktop, then drag it onto the icon of your havoc'ed disk - remember it is found at root level.
Reboot from your default unit, it should work now, should the mach kernel be the root of your problem (excuse the pun).
Hope this helps.

The 10.6.8 Combo Updater also installs the newer mach_kernel at Root level, and again the MBP would shut down during boot, before the login screen. Safe Boot would let me proceed a couple of minutes beyond login, before the mac would shut down without any error message. No clue in the system log (last entry before shutdown was "BUG found in libdispatch" - hm).
Again, replacing the mach_kernel file with the older version of which I had kept a copy, cured the problem, and as I am typing this, my MBP has been running without a hitch for almost one hour.
Another poster at MU (a_w) had similar problems with his MBP 13 Early 2011 after applying the MBP SW 1.4 updater, again with the new mach_kernel file being the culprit.
Hope this can help anybody having skipped the MBP 2011 software update and experiencing premature shutdowns of their new macbook pro after updating to Snowy 10.6.8.

Safe boot made it survive a couple of minutes longer, then it would shut down without a kernel panic. No clue in the system log (last message before shutdown was, however, that a bug was found in libdispatch - hm).
Then I remembered a similar problem after installing the MacBook Pro Software Updater 1.4, which amongst a couple of framework updates also updated the mach_kernel file at Root level. Replacing that with the previous mach_kernel file made the premature shutdown issue go away.
The 10.6.8 updater again replaced the older mach_kernel with the newer item, I found (using Path Finder). Fortunately I was able to boot from an emergency drive and then replace the mach_kernel with the older version. Voilà - everything runs stable now.
This problem seems to be specific to some MBP 13 Early 2011, as another poster here on MU (a_w) encountered a similar issue with his own machine, and again the newer mac_kernel appeared to be the culprit.
If anybody needs the old mach_kernel, I would be able to send it to him or her.

A mail with the zipped mach_kernel file has just been sent.
Tell me how it works out.

Upon attempting restart the machine immediately came up with code on the top left hand side (I wish I had taken a photo) saying that a system could not be found etc. I freaked out and re-installed the system (10.6.3) from the DVD.
The machine re-started fine. Has anyone experienced this. What do I do to update - will it happen again? Any ideas.

I installed this update on 5 different machines and every time the updated appears to install correctly and the machine restarts but the update is actually not applied and some software will stop working.
If you run software update it will show the update again and about my Mac will still show 10.6.4
I installed via software update and combo update and both with the same result.
