Apple Releases Revised Mac OS X 10.6.8 With Patch for Existing Users

I understand that Core Duo/Solo was only sold for 7 months (new). I was just saying that they could have made all of their systems 64-bit by waiting 7 months to update the lines.
Nevermind that those systems would still be limited to a paltry 3GB or RAM or 32-bit EFI.
Many of the early C2D Macs were limited to 3GB and had a 32bit EFI also. My C2D MacBook has the 32-bit EFI and runs Lion. You don't need a 64-bit EFI to have a 64-bit computer. Only if you wanted to go above 32GB RAM.
There was ample warning in all the computer press, including the relevant Apple sites that the first generation Macbook Pros and other Core Duo Macs sported interim chipsets and cpus and were little more than stopgap models and would never be able to run 64bit applications, let alone the OS. Heck, the first Macbook Pro 15" even dropped Firewire 800 only to return it with the C2D chip.
I waited.
And more: as soon as an application becomes 64-bit aware, it is allowed to access an additional set of general-purpose registers (r8 to r15) which did not exist in 32-bit x86 CPUs, and which therefore cannot be accessed by any software that is intended to be usable on 32-bit CPUs.
Having a greater number of general-purpose CPU registers means that a greater portion of a thread's context can be kept in registers more of the time, and kept in RAM less of the time. Placing more of a thread's context in registers opens the door to allowing a greater proportion arithmetic and logical operations within the thread to make use of register-to-register instructions rather than register-to-RAM or RAM-to-RAM instructions. Register-to-register instructions are significantly faster than either register-to-RAM or RAM-to-RAM because you don't have to go through the various bottlenecks of L1 and L2 cache misses, slowing data down to SDRAM speeds, and dealing with virtual memory swap-outs.
I was actually referring to the Macbooks that use the GMA950 and X3100. The X3100 MB's can use the full 4GB though.
Ah
Good news for my wife who is staying on SL until we get her ancient software upgraded.
For me, I'm on Lion and I really risked a lot in doing so - so far I've been extremely lucky in that I've had no show-stoppers thus far and I use a lot of custom software and equipment. More later if something blows up.

The thing about bounce is that it rarely bounces back to the sender. Spammers like to use non returnable origins for their junk. They don't need you to respond, they just want you to click on a link. On a side note, I'm amazed at how many people actually click on those spam links! There must be a lot, or spammers wouldn't bother to send out their crap. If people stopped clicking, then spam would become a thing of the past.
They do. It should be 10.6.7.1
I still have vivid memories of 10.3.3 and what a cockup that was, so updating day-of is a no-no in my brain.
Was that the one where the OSX installer reformatted any external drives that happened to be connected when you ran the upgrade?
back to snow leopard
I was one of those people who upgraded to Lion straight away in excitement to downgrade back to SL two days later. There were just too many little niggly things that became apparent the more you used it. The boot time was a lot slower on Lion and there were small things (I went to bounce back a mail message to find out that's gone, some third party apps were crashing etc..)
Back to SL my workflow seems much improved and the mac generally feels more stable and responsive. Don't get me wrong, I really want to like Lion - especially seeing I've already paid for it.

Indeed there is.

Did you apply just the Supplemental Update (10MB), or use one of the 10.6.8 updaters?
I can confirm that re-applying the Combo update will bump the build in the same manner. I'm curious whether the Supplemental update does.
I installed the 10.6.8 supplemental update, but have not upgraded to Lion yet. My computer is now taking *forever* to boot up, and dropping battery percentage like nothing else (25% in 1/2 an hour, with mild usage? Yeah, I don't think so). Anyone else having issues with the update?
Lion is ready.
Not a single problem since I resolved the one minor issue with Mail on launch day.
Everything works from Lightroom to Photoshop, etc.
