Contrary to belief, Snow Leopard by default (except for Xserves) runs in 32-bit mode. Check for yourself.
Code:
uname - a
You should see something similar

I forced it to 64-bit on my '08 Mac Pro and things were slower! Spaces was very slow. Dashboard was quirky. I say avoid it.
I recently installed Snow Leopard. It works faster than before and it gave me 8GB of space back. But, after looking through Applications in system profiler, I found out iTunes is not 64-bit unlike Safari and other native applications that have been re-written to 64-bit. I remember Apple said iTunes is also re-written. I must download a new version or it's included in an update (I'm waiting the 10.6.2 update to download at the moment)?

I know this has been asked numerous times, but most of the answers I found were old and archived. I was wondering whether or not an update or a guide has been released which allows a successful boot into 64bit kernel? Â On a side note, I have verified my computer does have EFI64. However I know in the past that this stil didn't enable a 64bit boot.Â

Whether anybody got Snow Leo build 10A380 (WWDC'09) successfully running with 64-bit kernel? If 'yes' - please share your method. I've tried every approach that i know: "6+4" keys, arch=x86_64 flag specified for both nvram and com.apple.Boot.plist, lipo command against mach_kernel.

On Apples site, it says that you need a Intel processor to run Snow leopard, but then below it says you need a 64bit processor which is what he doesn't have.
View 3 Replies View RelatedI know by default that Snow Leopard starts up in 32-bit kernel but anyone here boot into the 64-bit kernel? I think to do this you'd have to hold down 6 and 4 keys while booting.
By now almost all 3rd party apps are running 64-bit and all this time I've totally forgot about the 64-bit kernel!
I've just booted up to 64-bit kernel and all apps load instantaneously!
So, with Snow Leopard, there is a 32-bit kernel, and a 64-bit kernel. Correct?
As I understand it, it will boot into the 32-bit kernel by default, but if your hardware is supported, you can select the 64-bit kernel.
My question is - where is the list of supported hardware, and how do you select the 64-bit kernel?
My confusion comes from several posts and various articles which all say the first-gen aluminium iMac has a 32-bit EFI, and therefore can only boot into the 32-bit kernel. But I've just downloaded an app called Startup Mode Selector, which shows you your system config, and it says I have a 64-bit EFI.
Yes you read that right. Your brand spanking new MBP will use a 32-bit kernel as default.
You can force 64-bit kernel but some of your hardware will not be working.
So all that marketing crap about the benefits of 64-bit etc are all B.S.
I don't want a million threads about how this will not effect the running of 64 bit apps, etc. because it will. Your 64-bit app will run but it will not be able to address more than 4Gb of RAM.
There are also many more advantages to having a 64-bit kernel.
I did a bit of reading on the internet, and it looks like most computers will not boot into 32-bit mode by default with 10.6. It appears that if while booting the user holds the 6 and 4 keys, the computer will boot into 64-bit mode.
Does anyone know anything about this? Will the computer always boot into 64-bit mode if this is done once? Will it even make a difference? Will the average user want to do this?
I'm new to using Windows on a Mac but need to do it now for some video rendering applications that have transcoding, filtering, effects (like VirtualDub) that are only available on a PC.
I have a 17"MBP (3 months old), 2.8Ghz Duo, 4Gb RAM. I recently upgraded to Snow Leopard, was excited about 64-bit though I'm not an expert, I just heard it would be faster.
I didn't realize SL doesn't boot 64-bit anyhow, that you need to hold "6" & "4" at startup to get it to boot in 64bit mode. This surprised me because I figure many people assumed SL was 64bit! Just getting it to boot properly was a hassle. The 6 & 4 trick didn't work for me.
I had to edit the preference file which wouldn't save at first either because of permissions (I had to drag it to my desktop, edit it, save it, then drag it back to the folder and enter in my administrator password).
Only then did I realize my brand new eSATA Express Card didn't work in 64-bit mode. Upsetting because I just bought the hot new Sonnet Tempo card for $200 that claims to work with Snow Leopard. So until it works I'll be running 32bit mode on my Mac.
But if I want to run Windows 7, does this mean I can only run the 32bit version?
This article gave me a little bit more understand and also made me feel better that either booting in 32bit or 64bit kernel will not make a huge difference due to hardware limitation.

I was told to run Vista 64bit for games, but I was wondering about this� Since many applications don�t even have a 64bit version out and I don�t think games are 64bit, will they all run under vista 64bit? I have a feeling this might be a dumb question, but I just wanted to make sure before I go out and buy Vista 64.
Also do you think windows 7 is better for games? Will it even run games that have not been written for it? Or would I just be better sticking with vista 64 until everyone has caught up and made their apps compatible with the new windows 7? I mean will antivirus programs, ripping apps, etc work under windows 7 without a hitch, or should I wait and just use vista64 for now?
... long time reader, first time poster!! So I'm doing it. I'm switching from PC to Mac. I've been waiting for a while now and the new MacBook Pro's have convinced me. I'm buying the 13 inch this week.
However I'm slightly worried about the upgrade to Snow Leopard in September.
My question is if I buy a new MacBook Pro this week and upgrade from the current version of Leopard to Snow Leopard will it be the EXACT same as the version of Snow Leopard that ships with new MacBooks after September?
Is the upgrade just the same as the full software version available post September? Does the upgrade it just detect if you have the previous software and installs as if it were the full? Or does it just "patch" things depending on what's different from previous versions?
I can wait till after Snow Leopard is released in September 09 if it is different to Leopard upgraded to Snow Leopard.
I am using an HP Color Laserjet 3505n. Will snow leopard work with this printer?

Today I performed a clean install of Snow Leopard on my late 2009 Mac Mini. After completing the installation, I began running software update to bring everything up-to-date.While software update did find and install a number of updates (10.6.8v1.1 Combo update, Security Update 2012-002, Apple Software Installer Update, iLife Support 9.0.4, Remote Desktop Client Update 3.5.3, Airport Utility, Java, Safari) it did not find an update for iTunes (which starts at version 9.x, I believe, in a SL clean install).I assumed that this was some sort of random glitch and manually downloaded and installed iTunes 10.6.3.After that, I re-installed iLife '11 (from a retail DVD, not the App Store).When I ran Software Update again, it found updates for Garage Band, iDVD, and iWeb, but it did not show the updates for iPhoto and iMovie.I found this to be unnerving, as I performed a clean install when I first obtained this Mini a few months ago and didn't experience any of these problems - all of my Apple software updated automatically through Software Update without a hitch.
I began researching this problem online and found that other people have been experiencing this same problem (or some variation of it), and it seems like it began appearing around the time Apple updated some of its security certificates in March.In particular, I've found several references to the missing iPhoto update.This one is especially noticeable because an iPhoto library created in iPhoto 9.2.3 will not open in iPhoto 9.0, and this generates an error upon opening the program (i.e., a user backs up their iPhoto library created in 9.2.3, performs a SL clean install, reinstalls iLife, goes through the Software Update process until it shows that no more updates are available, and are shocked to find that they are unable to open their backed up iPhoto library because they have an out of date version of iPhoto).The most common (and admittedly logical) solution proposed in the threads I've read is to download any necessary updates directly from the Apple website. However, I am curious as to why this previously functional feature now appears to be broken.Has anyone else been struggling with this? Does it indeed have something to do with the new security certificates? Is Apple aware of the problem?

I'm currently using a MBP 13 inch and am running Leopard on it.
I just bought a copy of snow leopard today but i don't know if I should do a direct upgrade from leopard to snow leopard, or wipe my MBP and do a fresh install so i have snow leopard on a clean slate.
Have any of you tried the second option before? Or do any of you have advice on which path I should take?
I have my drive partitioned between Tiger and Snow Leopard. I am trying to move myself over to Snow Leopard so I don't have to keep switching.

I recently reformated my PC and put XP Professional 64bit on it, did all the updates that I possibly could. Installed/downloaded all my games, updates, patches. Customized windows with everything that I like. Installed my AVG 8.0 Pro antivirus, Just everything that I want with a PC.
is there a way to totaly save my entire windows install? Like if I were to upgrade from a 500gig to a 1 TB hard drive? I know some PC repair shops use a program to do this. I think it has the word "Ghost" in it? Is there another way also? I have an external 500 HD that I would save w/e I need to save on it to make it work.
I just read the seed notes for Snow leopard latest build and when reading what I can test 64 bit apps with seems pretty much any mac in -08 and -09 except (!) MBA and minis.
Any idea why?
I thought at least the MBA rev B would be 64-bit capable...?
My apologizies if this has been discussed but if so I have missed it.
I've got a mid-2007 C2D MBP with 64-bit EFI and obviously, 64-bit processors.
'6' and '4' on Snow Leopard won't boot into 64-bit mode. I don't need the 64-bit kernel at this point, but I'm mostly curious to see what drivers and apps breaks under a 64-bit kernel and the only way to find out is to try it.
There's a pretty nifty hack involving hex editing boot.efi that works for some suitable Macs:
[URL]
No mention of MBP, and my attempts at guessing offsets and values while hex editing didn't cause any booting issues but didn't result in 64-bit kernel loading, either. Anybody happen to know offset and value in boot.efi to mod for a MBP?
I know this is a real long shot type of question and I'm not expecting anybody to know. But if you do, would love to find out.
My Windows XP partition is getting claustrophobic and it's about time I upgraded from an 8 year old OS.
Anyway, what's the easiest way to do this? I assume it'll have to be a clean install to go from XP to 7 and 32bit to 64bit.
I have a fair number of programs and several gigabytes of Steam games which is why I haven't done it yet.
I have a 15'' unibody mbp with the 9600M, and the nvidia notebook driver installer always fails to recognize my graphics card and quits. Is there a way around this? I have tried modifying some INF files but it doesn't work.

The MB appears to meet all the criteria (64bit EFI, right processor, SL) - but neither the apple sudo terminal command, nor the 6+4 key at boot work in setting 64bit kernel. Any other suggestions?
I want 64bit because it provides improved security (NX bit in HW, less chance of exploits due to smaller market share)
