Performance impact of the 32 bit kernel is not really known yet.

All apps benefit in speed under SL. Do I need to repeat this again? 64-bit apps obviously have the biggest speed increases but 32-bit apps have been heavily optimized as well. This is the last time I'm going to repeat this. And yes, the difference is tremendously noticeable with both 32 and 64-bit apps on my 2nd gen MBP.

Besides some key apps not working or not working 100%, once these kinks are worked out I would then be likely to say this is one of the best Apple updates ever under OS X, even if there was not much added in terms of bling. But what they did add is tremendous.

unfortunately, I don't have one of the 64-bit models that are addressed by SL. But I do love the speed increase.

Ok, I have a question. I spent the majority of today perusing forums here, among other place, and still, I cannot find any real conclusive evidence that tiger to snow leopard (without the box set) is successful. can anyone tell me, is it? I myself am running tiger on an original MBP 1.83 Ghz and am just plain curious. If I were to do the upgrade to snow leopard without the ilife '09 box set, would this indeed work? I have yet to hear from some one that they have successfully installed it, despite all the rumors saying it is possible. any info is helpful info.

QuickTime X uses the H.264 hardware decode whether you have the 9400M enabled or not.  Switching GPUs had no effect on the CPU usage when playing back H.264 files which either means if any GPU has the necessary hardware decode circuits, it uses it, or it still uses the 9400M even though it is technically disabled and not driving the screen.

That's correct; the 9400m is always enabled. It can also be used for OpenCL operations even if the 9600 is currently driving the display.

Yes, it is successful. SL by itself or in the box set is the same exact thing. It’s just not technically “legal” to buy the single one as not an upgrade.

It is 100% possible.

What I am trying to find out is, has anyone actually done it? I have been reading elsewhere that there are some complications with this way of doing it.

Also, what are thoughts on OWC labeling the disc as an "upgrade disc"

I've done it.

I installed it to a blank partition on a hackintosh. The disc is identical. There is absolutely no difference between the standalone SNow Leopard "upgrade" and the family pack version, except supposedly the EULA (which I didn't read, and obviously disregard anyway).

Just so I'm absolutely clear on what you guys are saying. I have 10.4.11 currently on my MacBook Pro since that is what it came with. Last spring I bought the Mac Box Set (10.5). At launch I pre-ordered the retail ($29) Snow Leopard (10.6). When doing my upgrade I can skip installing the 10.5 disc and instead use just the 10.6? Then I will use the Box Set iLife and iWork to complete the upgrade?

Airfoil provided me with a link to their latest build. It's funny, because when you launch it it says it needs to relaunch Safari in 32-bit mode to run, so I now use Firefox if streaming and Safari for everything else.

So - FYI - Snow Leopard killed my iMac's FireWire port.   My FW external hard drive refuses to mount, my Panasonic Camcorder doesn't mount, and system profiler just gives an error when I try to list my firewire devices.

NUTS!   I thought I had a completely problem-free upgrade, but that's not the case.   I did a bit of searching on Apple's support forums, and I'm not alone.   Apparently it ganked lots of people's FW drives.

I know it's a software error, and not a hardware failure, because I'm currently running Vista Ultimate through Boot Camp on the same computer and it's importing my HD video right now while I type.

YEARGH!

Yeah, must depend on the drive. My FW external drive works like a champion.

This upgrade has been great for me. The developers just now need to catch up and write their apps all in 64-bit.

From what I can tell -- it's an age issue... devices more than a year or so old seem to be tanking.   Is your drive brand new?

I also read today that the 10.6.1 update fixed some of these issues for people, if they also did a NVRAM/PRAM reset.   I'm burning a DVD right now, but when that's done, I'll try it and see.

I am running 10.6.1, and that alone did not fix my problems.
