I've skimmed thru most of the threads/replies thus far — has anyone else noticed that repairing permissions is significantly faster?

This is probably the nicest feature, and one that Apple's target audience least cares about.

Really most relevant to Snow Kitty Server.

I have seen a few puzzlements and areas of concern, but those'll have to wait a bit yet.

On virtualization, I think Apple's so far away from the enterprise market, that it wouldn't even make a difference.

I guess it's sad, then, that this decision was obviously no accident on Apple's part. Strange that I've read they're "trying" to make some headway in the biz market. Oh well.

So does anyone know if Keynote uses Quicktime X to playback H.264 files.  Should be able to check by looking at the processes and seeing if a new 32bit QtKit thread is spawned.

How do so many people loose their installation media? Boogles my mind.

Come to think of it, suppose my wished-for Snow Leopard installation should go completely haywire.  How would I order replacement Tiger DVD's from Apple, and how much would said replacements cost?

If you really owned Tiger, you would have been able to perform a backup via Time Machine.

Time Machine is not a part of Tiger.  It was introduced with Leopard.  Tiger contains no self-backup system.  For that matter, I could simply use SuperDuper.  I'm not looking for a backup system, though.  I'm asking about obtaining original install media.

Without going back 4 more pages to check...

Apple's Snow Leopard downgrades Flash   3 September 2009, 09:02
Apple's Snow Leopard, Mac OS X 10.6, downgrades the Adobe Flash Player installed on systems being upgraded with the updated operating system. The Flash Player version with Snow Leopard is 10.0.23.1, which is a later version number than the most recently reported vulnerable version, but it was being distributed at the same time as the flawed version and most probably suffers the same critical security issues. Adobe have confirmed the issue exists and recommend that Snow Leopard users update their Flash Player as soon as possible, by visiting http://get.adobe.com/flashplayer/ and installing version 10.0.32.18. Users can check what version of Flash Player is installed by going to Adobe's version check page.

During the development of Snow Leopard, and as far back as early July, developers were shipped beta versions which included Adobe Flash Player 10.0.23.1. [..]

Snow Kitty also default boots to a 32-bit kernel unless you hold down 6 & 4 during boot- something about device driver readiness. Having trouble re-finding the article. Hopefully more soon.

I've read this has no impact on either 64 or 32-bit apps as far as their performance goes. 64-bit apps (most of Apples new OS and a few 3rd party apps written in 64-bit) will run seamlessly between 32 & 64-bit apps and their speeds are not effected. YOU DO NOT NEED TO BOOT INTO 64-bit MODE in order to run 64-bit apps at full 64-bit speed. This is just one BIG reason SL (I think) is so great. In fact, I've heard that even 32-bit apps run faster under SL due to the fact the OS is so heavily optimized to run programs at their maximum speeds regardless of whether they are 32 or 64-bit.

Netkas on 64-Bit Snow Leopard

Kernel defaults to 32-Bit on all Macs except for XServe, to maximize compatibility.  Some third party software (not even drivers, necessarily) requires a 32-Bit kernel --For example Parallels Desktop and VMWare Fusion.  It's not really a big deal, and I think Apple made the right decision.

To make the OS default to 64-Bit kernel on startup, add "arch=x86_64" to your com.apple.boot.plist file.

I'll wait for the English instructions, thanks.

1. Type "com.apple.boot.plist" (without quotation marks) in the spotlight bubble in a finder window, or find it in /Library/Preferences.

2. Open the resulting file in Textedit.

3. add the line "arch=x86_64" (without quotation marks)

4. Save the file.

You probably won't be able to save the file in Text Edit.  You might need to run TextEdit as Administrator.  To do this, open the Terminal and type:

sudo /Applications/TextEdit.app/Contents/MacOS/TextEdit

then open up the file.

Then do as netkas says:

find there:

<key>Kernel Flags</key>
<string></string>

and change it to

<key>Kernel Flags</key>
<string>arch=x86_64</string>

And no I haven't tried it.  Hackintoshes load the 64-Bit kernel by default!

As mentioned, some apps and drivers require the 32-Bit kernel.  In theory, you really have no business running the 64-Bit kernel --except for bragging rights.  Use at your own risk.

It's worth mentioning that you need a 64-bit EFI chip to fully benefit from 64-bit. You can hack to load the 64-bit kernel, but only 3GBs RAM will be recognized.

Performance impact of the 32 bit kernel is not really known yet, but likely slight if any, not noticeable, and no one seems to have complained so far. Not a major worry atm.
