What are you talking about, there are 32bit and 64bit versions of Snow Leopard. Snow Leopard will run on ALL INTEL Machines regardless of 32bit/64bit support. It'll run 32bit kernel when there is no 64bit CPU or if there are missing 64bit kexts for the hardware. This is a proven fact that has been known since WWDC. Running 64bit applications is never going to be a problem, you can run 64bit applications on leopard as well as 64bit processes on Tiger.
developers-can anyone say-i know that for the 10.6 upgrade disc you need to have 10.5 already installed-or at least owned;
I would never install a major update ontop of another-I would fully wipe the HD and install;
The question: MUST you lay down 10.5 before you can install 10.6 as an update on top? That can lead to problems on down the line
Or can you do it like this as can be done with Windows: from a wiped clean disc, I install Windows XP Pro UPGRADE disc on the clean HD-after a bit of searching and minor installing we come to a challenge page;
It will ask to see a valid copy of XP Home before it will proceed with install;
So you pop out PRO disc and slip in the HOME disc when this is in, and 'seen' you may proceed to the main screen which gives you all install options;
I then eject the HOME disc and reinsert the pro and click the install button-and it proceeds to install the full XP Pro with no trace of Home-which parts are already integrated into the pro update disc
To me one integrated installer is superior
So ideally I would like to wipe my disc of 10.5 and install nothing but the 10.6 system
will this work?

You'd think it would be possible right? My restore button is disabled out. I tried to restore on a hard drive that already has a partition of SL and on a flash. Neither of them seemed to work. I'll give it another go.
Umm, I should check it. I'm making another partition on my drive at the moment, let's see if this works. This might take a while.
Can anyone clarify whether 10A432 is running in 64bit mode which before was only running in 32bit mode? I know my iMac runs in 64bit mode but my MacBook white is still running in 32bit mod - its pretty crappy if Apple kills off support for a laptop less than a year old.
Each successive seed enabled by default 64bit kernel booting for certain models. There are some models that works perfectly fine in 64bit kernel but was not enabled by default, had to modify the boot.plist to get it to work. You have to look in system profiler and figure out if that build has all the 64bit extensions for your hardware, most likely it won't have 64 bit extension for your intel integrated graphics and that means no 64 bit kernel for you. You can run 32bit kernel, SL is still super fast in that mode. I have been running in 32 bit even tho ever since back in 10a394, I had full 64 bit support, I turned back to 32 bit due to little snitch and LLC not working in 64 bit.
All of it being made by you voicing on matters you know nothing about.
Snow Leopard is 32/64bit - the 32bit version uses PAE which provides 36bit addressing.
The issue for those of us still in 32bit mode has to do with the fact that not all the drivers are 64bit - My MacBook has a 64bit processor (Santa Rosa) but due to Apple being too bloody lazy to create a 64bit X3100 driver, I am stuck in 32bit mode.
I swear I'm tempted to move to Windows 7 due to Apples pathetic support of computers that are less than a year old, 64bit capable but they decide to cripple the experience for their customers.
What do you need 64bit kernel for? You can still run 64bit applications. It won't magically make your system any significant faster than the 32bit mode.
If you don't like it, just move to W7 already. Apple doesn't require you to have OS X on your Macs.
I'm sorry i'm a little outdated, I don't see the update on software update...
do you have to buy it?
i just read the 4th page... and seems to me people have it already?!?
and how?

in your opinion, should i be upset and/or disappointed that my two year old mac pro won't run snow leopard in 64 bit? Do you think i'll i notice a difference in performance between how it runs on my mac pro and my unibody macbook?
Well that is just ****house; a computer less than a year old and Apple kills off support for it. Apple might as well tell all customers with computers older than a year to kill themselves because they're useless to Steve's grand master plan.
I am willing to put up with PowerPC being killed off but this is bloody pathetic that a machine they sold up until a year ago, the support has been killed off from it. There is nothing stopping Mac OS X from running in 64bit mode, there is no hardware limitation, its Apple choosing to be a grade 'A' prick and fail to make their X3100 and 950 drivers 64bit.
Oh okay thanks brother!
I don't know what ADC is but i'm sure it's some sort of developer thing.
but that's cool.
I can't wait til it's available for everyone... if that does happen
EDIT: rofl ADC Apple Developer C... something?
that's something from the top of my head. don't know if it's right
- Ya, so high quality that Microsoft still hasn't figured out how to create a filesystem that has very low fragmentation that doesn't require any external application to fix.
- So high quality that Microsoft still doesn't fully follow web standards in its default browser.
- Still can't create an OS that doesn't require multiple reboots for installation.
- If by high quality interfaces you really mean cluttered to crap interfaces, then I totally agree.
- Still haven't created a decent, secure shell scripting language preinstalled with every OS.
- So high quality they a have to sell 8 different versions all crippled in their own fantastic ways!
- You really want to compare the registry vs defaults ?! Can't believe MS hasn't just ripped Apple off on this one. Same thing with Linux, defaults is just bad ass hands down.
- How much do they still charge for development tools ?
- Performance of SMB is still down right awful.
Seriously, the list goes on and on. Its one thing to use the tool that fits you best and its worse to ignore downright flaws in a product and use the tool anyway.
I couldn't imagine a world where I actually needed something from Microsoft. I used Linux for 5 years straight, and I always needed Microsoft for something. With Apple, that is not the case. Sure, I don't get the games but I got a PS3.
Would I ever buy a 360 ? Well, they finally solved a majority of the rod issues so I might. You heard it here first, I think the 360 is a quality product.
Anyway, Microsoft is on the right road. But they got a hell of a long ride to go.
For the same reason I want to smoke a joint - because I want to.
Its like the argument over lossless versus lossy music - I can't tell the difference but it is the principle of the damn thing; I'm not going to hand over money for a castrated product that Apple couldn't be bothered to extend basic system functionality to all Apple customers.
I want my whole operating system to be in 64bit mode - the reason for it is, quite frankly, none of your business. What I am demanding isn't more than what I'd expect from a vendor. If Microsoft can do it - so can Apple.
No, it is a complete disc image available only to ADC developers. It'll be out next month for the public.
You won't notice any but very slightly (<2%) difference between running SL in either 32 bit or 64bit mode. You can still run 64 bit applications in 32 bit SL. You still gain the benefits of GCD/OpenCL, 99% of the stuff that you have does not require you to have a pure 64 bit OS.
Dude, Apple did not kill off any hardware except for PPC, you can still run Snow Leopard and gain all the benefits of it. There's nearly nothing you can do in 64 bit mode that you can't do in 32 bit mode.
If you have a Core 2 Duo, you have a 64bit CPU which can run 64 bit applications, it does not matter if Snow Leopard runs with a 32 bit kernel or 64 bit kernel on your machine, either will run 64bit applications fine, you are able to run 64 bit applications on Leopard as well. There's nothing special about have a pure 64 bit OS.
So go back to Microsoft and use their W7. They have perfect 64bit support and they're happy to have you. Apple is NOT obligated to extend support for future OSes for you, it's their loss and MS' gains.
There are security improvements with 64-bit kernel support as well. Particularly, memory randomization is definitely more random with a 64-bit address space. Poor memory randomization implementation in Leopard was one of the major concerns pointed out by Charlie Miller of Pwn2Own fame. Even for models that don't support more than 4GB of RAM, having a 64-bit kernel would be useful to improve security. It's not like you can ever be too secure, especially with OS X's user base and profile ever growing.
There are a whole host of benefits you get when in 64bit mode - if you choose to ignore the threads on this website along with other technology websites, I'm not going to do your homework for you.
