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 RepliesYes 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.
Bought a new Macbook Pro 2.8 a few days ago (newest one with longer battery), it shipped with Snow Leopard. However, I believe the Hardware is still the same as before Snow Leopard was released, so it should work with Leopard 10.5.
If I try to use a Leopard disc it just doesn't boot, or it comes up with a kernel panic. I even installed Leopard on my 2.5" in my Mac Pro first, then tried booting it on the macbook pro. Same thing, kernel panic. Have they added some kind of lock to the hardware that stops Leopard from being loaded? I thought they would only do that when new hardware is released.
I've seen something about com.apple.boot.plist, but I need a little more further information. After type: Code:
ioreg -p IODeviceTree -w0 -l | grep firmware-abi
I receive the following from terminal:
Code:
|| "firmware-abi" = <"EFI64">
Looks that I am able to run 64-bit kernel.
My computer is a white macbook early 2008. Core 2 Duo T8300 2.4GHz.
Is there something about the hardware on this iMac that will not let SL run in full 64 bit glory? It loads 64 bit kernel, but did that in Leopard as well. SL loads the 64 bit kernel but not the rest of it... of course holding the 6 and 4 keys results in no joy. So now I suspect it is not just the CPU that must be a 64 bit ready chip but the rest of the hardware must be like wise optimized.

Then on Wednesday when I shut down it goes into a kernel panic and tells me to restart. When I go into the other user account it does not do that. I have a picture of the error log that i got when I started the computer up to submit to Apple. Can someone please help.
I have reset PRam, repaired permissions, and reinstalled Snow Leopard but recovered it from a Time Machine Backup. I do not know what to do.
I have been trying to boot into 64-bit kernel in Snow Leopard on my Late 2008 Aluminum MacBook (2.4 GHz), but it is not working. It is running the 64-bit EFI firmware and is updated to 10.6.1.

Good news - found a remedy in disabling my screen saver.
I'd like to use my screen saver without getting kernel panics. I've tried erasing my drive and restoring from a back up. resetting PRAM, repaired permissions and ran Tech Tool Pro 5 (file structures and repaired permissions, everything else checked out fine).
I'm running a MacBook Pro (15-inch, Mid 2009) and am getting daily (sometimes multiple daily) kernel panics. It's been months since hardware changes (upgraded to 8Gb RAM, quality modules that work fine on other identical Macs). Today is the first day that it's happened more than once, but I hope that's not a sign of things to come... Here are Pastebin dumps of the Problem Report, System log, and Console log.Â
I haven't done any serious software updates in a while, but I did set up a Windows XP VM in Parallels Desktop, which has been running during most kernel panics. Maybe bad drivers that are incompatible or need updating? It sometimes runs for hours before a panic, so I don't think running in Safe Mode would be effective (unless I take it home overnight, which I may try). It seems that my problem is similar to another thread I found on this forum, but mine is a bit different, and I don't run any microsoft hardware (Logitech keyboard and mouse).

Apple's site about Snow Leopard says that 64-bit *apps* under Snow Leopard will be more secure than ever due to several things:A more secure function argument-passing mechanism and the use of hardware-based execute disable for heap memory.
Memory on the system heap is marked using strengthened checksums, helping to prevent attacks that rely on corrupting memory.
Nerdly question, but does anyone know if any of these types of security enhancements require the 64-bit *kernel* (not just a given app)? My white Macbook (C2duo) is unlikely to run 64-bit unless Apple lets it in their final release (it apparently won't so far as they haven't written drivers for my lowly machine).
I've upgraded my MBP to Snow Leopard today from Leopard and I'm getting a Kernel Panic when I login as one user. Logging in as an Admin user or a new user account is fine, and I still get the Kernel Panic if I boot up in to Safe Mode. It's obviously a problem with the user account and looking at the dump log it seems to be caused trying to mount something, but I can't for the life of me track it down.

Installed Snow Leopard (retail box) onto a last-gen Aluminum MacBook Pro (2.6Ghz model). Did a time machine backup. Put in CD and upgraded. Rebooted with no peripherals plugged in and I get a kernel panic. There's only one user on this machine so I can't see if it's an account problem. I did the same thing on both my Macbook Air and 17" MacBook Pro.
Question: Do I have to now Reinstall Leopard (fresh)
Then update Snow Leopard
Then restore from Backup?
OR
Install Leopard
Recover from time machine backup
Then install Snow Leopard
I don't have all day and really don't want to screw up the process. Is there any thing else that might say why this kernel panic is happening?

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 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 RelatedOver the weekend I tried to backup my MacBook Pro onto an external harddrive, and when about 23Gb out of 110Gb were completed, my mac went into a kernel panic ("You need to restart your computer. hold down the power button until it turns off, then press the power button again." in four languages). Previous backups went fine. So I did a reformat of the ext. hdd, same thing: after about 20 or so Gb of backup, the msg. pops. otherwise the mac runs without problems. Did a virus check, which came up negative.

I have a Snow Leopard Install Disk for the 13-inch Macbook Pro model.I also have a 21-inch iMac. I have OS X Lion installed on both. I have Snow Leopard installed as a partition on my Macbook Pro, which I installed via the install disk. I want to do the same thing for my iMac but I am unable due to (seemingly) my install disk is for a Macbook Pro and not for an iMac.

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 out of nowhere my unibody MBP (specs, etc below) locked up yesterday while I was watching a video using VLC. It stopped responding to anything so I held down the power button until it turned off. I waited about 10 minutes and turned it back on. Grey screen with spinning cog showed up for about a minute and then kernel panic. Held down power button until it turned off. Tried repeatedly - same results. Won't boot into Safe Mode - still get a kernel panic everytime. It will let me boot the machine into Target Disk Mode. It will boot from my Snow Leopard install disk where I ran Disk Utility and "repaired disk" and "repaired disk permissions" on both the drive and the volume. All the "repair disk" and "repair disk permissions" ended with messages in green type saying that the disk/permissions appear to be OK.Â
I have an external FW drive used for TM backups for the machine. A fair amount of data has been added since the last TM backup (which was less than 30 days ago) that, ideally, I'd like to not lose by resorting to restoring from a TM backup. It's not the end of the world if the last (roughly) 30 days of data/changes ends up being lost, but I'm willing to work on getting it back up and running without doing an erase and install and then restoring from a TM backup if at all possible.Â
Definitely if any other information or data is needed from me in order for anyone to assist, please let me know what it is and I'll do my best to provide it.Â

[Code]...
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?

How to do a safe reboot on my MacBook Pro when kernel panic message appears?
Info:
MacBook Pro (13-inch Late 2011), Mac OS X (10.7.3)
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.
This is the first time i reinstalled(clean install) my snow leopard on my MBP. All went fine but then i inserted the disc for bundled application (which contains the ilife apps) but it keeps failing.Â
It says that "the installation failed. the installer encountered an error that caused the installation to fail. contact the software manufacturer for assistance".Â
I've also done my research on this matter. I've gone thru a few steps i tried as below without success:Â
1)normal install - fail
2)repair permission - fail
3)install in safe mode - fail
4) install using another admin acc - fail
5) made an image out of the disc and install - fail
6) used a similar disc(my dad's since we have identical version) - fai
7)updated my system and install - fail
8) reinstall the mac - failÂ
i cant think of any other solution as im a bit noob when it comes to mac. is there any other things i could try before taking it Apple?

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?
The internal hard drive on my early 2009 iMac is being replaced but I have to reinstall Snow Leopard myself.I did search in MRoogle and at Apple and cannot seem to find instructions on how to perform a clean Snow Leopard install on an iMac internal HD.
Can I do this? And if so how? Or do you think I should try and install Leopard on the existing Hd in the iMac? I still have these discs but have to get the SL applications install disc out of my drive (it's stuck and the iMac won't boot past the blue screen).
I jsut did a fresh install. wanted to use my SL DVD but the MBP i5 refused to star with it so I used the original DVD (10.5) and upgraded with the SL DVD to 10.6. However after the initial SL Installation, it tried from the SL DVD and this failed. I did a manual restart, starting from the HD and everything ran fine. however today I note there is a locked file on the HD named Mac OS X Install Data. It contains 181 .pkg files.Now I suppose this should have been moved or deleted as part of the install process. Can I move them to a file where they belong?Â

Did a search through here but couldn't find anything concrete. What are the differences between a fresh Snow Leopard install and a factory Snow Leopard install? I ask because I bought an Intel SSD and don't know if I should bother cloning the hard drive that will come with my new 15" MBP or I should just install a fresh copy from a Snow Leopard install disc. I'm aware macs come with next to no junk pre-installed, but are there some factory settings that are worth preserving if they aren't documented well?

The reason for this is a long story. My logic board was replaced and my Mac was wiped clean. I am not trying to recover from back up but could not figure out the next step after the recovery finished. So I tried to install OSX from the disk that came with my Mac. Probably not the right corrective action. Â
I need to remove the Snow Leopard DVD and finish my recovery.
iMac with 2Ghz Intel Core 2 Duo, 4GB RAM, plenty of space available and currently operating 10.5.8. Now I want to upgrade to Snow Leopard and since my Mac Mini came with it, I attempted to use the OSX install disc from the Mini in the iMac. I don't see a reason why this shouldn't work. There's no DRM or anything as far as I know. I'm just trying to bridge the gap so I can download Lion. I've looked into some of the advice others have given on this subject but my computer doesn't have those issues. I've tried booting from disc but I get the same message.
