I 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 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.
View 24 Replies View RelatedI'm currently running Word for Mac 2008 on an iMac Intel with Snow Leopard. I do a lot of document writing, often switching back and forth between documents. I find it a pain to have to go to "Window," find a document, opn it, then go back to "Window" to where I was originally.
I've bene playing around with Scrivener and I really like how it lines up documents on the left and then you can import them into a split screen. Does Word 2011 have anything like this?
Today when we started trying to add users to our server (we use it only for afp access at this time), we noticed that new users belonging to a group "storage" were unable to login from client machines via afp (clients both 10.7.2 and 10.6.8). Â
When we tried editing the users accounts to change which groups they belonged to, it would appear in workgroup (and server preferences) that the changes would take but there was still no access.Â
As a test case, we modified an existing user who had no issues logging in to belong to a diffenent group and have different sharepoint access. The changes looked good in workgroup and server prefs, but when the user logged in, he was only able to acces his old sharepoint and not the new one (and since his permissions to the old were removed, he shouldn't have access to that sharepoint).Â
Also, for some reason users cannot be deleted within workgroup manager any more. The login used was the diradmin account.

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)?
View 9 Replies View Relatedjust got me a brand new 2010 MacPro 2 x 2.4 Quad-Core with 12GB Ram and the ATI 5870. This is the first MacPro to system boot into the 64bit Kernel by default (ie, hold 3+2 on restart to boot into 32bit Kernel). One of the first things I did was run the Photoshop performance test, which FYI on my old G5 2.7 with 4GB Ram returned a time of 114 secs, and on the new Quad-Core in 64bit kernel returned a time of 14 secs, so as you can imagine I was pretty happy with the results.
Then the problems started...... when I was installing software I got the dreaded Kernel Panic, restart your machine screen. So I did, and it happened again on restart, so I did, and it happened again on restart, so I did.... you get the idea. So I put the system disk in and restarted, then reloaded OSX10.6.4 and everything seemed to be going fine, until I installed software again (different app from the first time), and I got the Kernel panic screen, then again on restart etc, so I booted into 32bit kernel and all is good. EXCEPT! - When running the Photoshop test in 32bit Kernel it returned a time of 17secs. Now, I know I am being picky here, but I do a lot of work in PSCS5, and by a lot I mean sometimes all day on large photographic images, so 3 secs is a big deal....
My brother has the first generation of the iMacs that has a Core duo processor (not Core 2 Duo). Will snow leopard work on it? 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.

I convinced/helped a friend upgrade her 1.83Ghz CD MacBook to Snow Leopard. It has not been a smooth ride. Right off the bat there have been persistent and recurring DNS problems. She has also found that it won't shut down without her going through and quitting or force quitting open apps--skype being of particular issue. Tonight she had a kernel panic, it seems. It appears skype is the problem app, but this didn't occur before the SL upgrade. Is it coincidental or correlated?
View 2 Replies View RelatedI currently have external storage devices by DataRobotics - 2 DroboPro and 1 DroboElite. I bought the new MacPro 2 months ago and have been having problems with the Drobo devices disconnecting constantly. After a lot of diagnostics including Apple replacing the logic board in my MacPro, it was identified that the issue was with the iSCSI initiator that DataRobotics uses. It is not 64bit kernal compatible and as a result, the drives disconnect randomly especially when moving data from one external drive to the other. I am forced to boot the MacPro in 32bit kernel mode for the drives to work properly. DataRobotics is not committing to fixing the 64bit kernel issue so I'm now looking to replace this technology.
I found some interesting technology by Netgear and was considering buying their product, however, I had the worst experience ever with dealing with pre-sales & technical support department, after dealing with 4 different individuals, I concluded that they have no clue about their own products, the staff is so junior, it's as if I called a completely different company when talking about their own product. I am therefore going to stay away from that company.
I've recently acquired an iMac and wanted to upgrade to Lion, however I believe I need to upgrade from Leopard to Snow Leopard first - which could prove to end up costing a fortune! I've read recently that Apple are offering the upgrade to Snow Leopard free of charge for MobileMe users, however when I've followed a link to fill in a request form, this just takes me to the Find My Phone feature on iCloud.Â

In order to perform either function, I have to log onto my wife's account and log it out before it will allow me to either restart or power down the computer.
If I try to do so while both accounts are logged in, I will get the usual prompt for an Admin name and password, but then it just won't go past that screen. The prompt just keeps coming up to enter the Admin info. Anyone else experiencing this, or have any recommendations?

My computer is a white macbook early 2008. Core 2 Duo T8300 2.4GHz.
Just wondering what the thoughts everybody was having regarding loading Snow Leopard with a 32bit kernel (i.e. "normal" install) or 64 bit kernel (i.e. holding down the "6" and "4" keys during reboot).
View 8 Replies View RelatedI 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?
