DMG mounting issues & Seatbelt.kext

* LAST EDIT 08.28.09

The Problem
Kernel Panics which happen during the mounting if Disk Images (.DMG) are caused not having the correct matched seatbelt.kext for your kernel.
You can correct the Disk Mounting issue by matching your kernel with the proper seatbelt.kext build.

If you have the 9.5.0 kernel you will need the Seatbelt.kext from 10.5.5
If you have the 9.6.0 kernel you will need the Seatbelt.kext from 10.5.6
If you have the 9.7.0 kernel you will need the Seatbelt.kext from 10.5.7
If you have the 9.8.0 kernel you will need the Seatbelt.kext from 10.5.8
-- I have to say this for some people

Check your kernel version by opening Terminal and typing:

What is this file and why its important
Seatbelt.kext was introduced in 10.5.5 and is a sandbox security measure. You can find out more information about what a Sandbox is here:
http://en.wikipedia.org/wiki/Sandbox_%28computer_security%29
http://www.usefulsecurity.com by c-had

Differences: Apple has updated the seatbelt in their 10.5.5 single and combo updates. The below information may only be correct if you installed or updated before February. I have added the updated differences below the old & have added links to both versions
The version numbers are the same but you can easily tell the difference by size or checking the info.plist for the build number.

Updated Seatbelt Differences
Apple continues to modify files in older updates. I can say for certanty that the following list of files go with their appointed version but you may come across files with completely different versions, builds and dates.

The version numbers are the same but you can easily tell the difference by size or checking the version.plist, NOT THE Info.plist for the build number.

Extracting it from an update
You can use Pacifist (Available here: http://www.charlessoft.com/ ) to extract the seatbelt.kext you need from the Combo Updates available for download on Apple's site or from the appropriate install DVD. If you are downgrading, I would recommend backing up your existing version before replacing it as you may need it if you upgrade kernels. Voodoo Release 1 Kernel users should do this especially as a new version, using the latest 9.6.0 kernel, should be released shortly.

Drop the Seatbelt.kext that you want to add to your system on to your desktop. Open Terminal and type the following:

In short:

Reboot using the boot-flags -v -f

Steps explained:

1. Give yourself root privileges so that you can modify files.

2. Make a backup copy of your existing Seatbelt.kext. First we will make a directory called "backup" in our root directory and a directory in it called "seatbelt" to store them. Open Terminal and type:

3. Change directories to /System/Library This will shorten some of the commands we have to type in.

4. Copy Seatbelt.kext to the new "backup" folder.

5. Copy the kext from your desktop to the extensions folder

6. Set the proper permissions for the extensions folder.

7. Set the proper ownership for the extensions folder.

8. Touch the extensions folder

9. Remove the extensions cache to force OSX to rebuild it with our new kext.

10. Repair permissions to your drive.


11. Reboot using the boot-flags -v -f
-v Verbose Mode displays useful information during the boot process.
-f Forces OSX to load kexts from the extensions folder instead of the cache file. We did delete the cache file so this is just a precaution.

There are shorter methods to do this but this should cover everything for those who have issues installing kexts and may solve other issues related to permissions.

Do not PM with questions regarding this post. Reply to this post and I will try to reply as soon as possible. My PM mail box fills up on a regular basis and I am unable to use it for what its for.... Private MSGs

umm im having problems, and im running version 9.5 voodoo kernel but my version of mac is only 10.5.2.... having crashes with dmg images though... :-/ so what gives ?

I have the iPC 10.5.6 with a StageXNU 9.4.0 Kernel, so which one should I use?
Edit: Solved, manually installed a 9.6.0 Kernel
BUT: How could I possibly get the seatbelt.kext with Pacifist, if installing Pacifist requires to open up a *.dmg file?

wheres the attachments. WTF!

Hi, I have the same iPC 10.5.6 also with 9.4.0 kernel. How do I upgrade to 9.6.0 ?

Thanks.

hey dude.

i found your comment on a issue with diskimagemounter on hackintosh.
i have exactly the same problem with my hackintosh.

i already have the 10.5.5 seatbelt.kext on de desktop but by some of the commands i type in terminal i get error's

sudo -s
mkdir /backup/Seatbelt
cd /System/Library
cp -r Extensions/seatbelt.kext /backup/Seatbelt/seatbelt.kext
cp -r ~/Desktop/seatbelt.kext Extensions/seatbelt.kext on this one i get error's (permission denied)

chmod -R 755 Extensions/ on this one i get Operation not permitted

chown -R root:wheel Extensions/ this one works

touch Extensions/ touch: Extensions/: Permission denied

rm -Rf Extensions.mkext rm: Extensions.mkext: Permission denied

diskutil repairpermissions / Started verify/repair permissions on disk disk2s2 MACSYS
[ | 0%..10%..20%......................................... ]



can you please help me with this because with me also mounting a dmg gives me a kernel panic.

You open Terminal run sudo -s and then leave it open while entering these commands.

If you have done this then lets check a few things.

1. Open Terminal and type:

Should return this:

If not then type this:


2. In Terminal type:

Should return:

Let me know if it doesn't.

I have the kernel panic while mounting DMGs as well. I have installed the latest version of iDeneb (1.4) and selected the seatbelt fix. So I have been able to verify that the seatbelt.kext that is installed is the correct size and version, from 10.5.5. However, I believe my system.kext is not matched to the voodoo kernel 9.5.0. I have tried rolling back my system.kext with Kexthelper, repairing permissions, touch the folder, etc but this yields to instant kernel panic on reboot. Does anyone have any suggestions on how I can get my version of system.kext, seatbelt.kext and the kernel (would like to use Voodoo 9.5.0) to match without causing instant kernel panics when I reboot?

Thanks man for the support...

i got it finnaly working now. altrough i also have another little problem.
the problem was that i after sudo -s he asked for a password.
here i pressed just enter and that was the wrong part.
after entering my owne password it worked fine.

my other problem is my terrible bad connection on LAN.
my uploads on MSN are low, and if i watch youtube or anything my connection even hangs.
i need a reboot to get it working again.
in networks i also see there is no cable connected, but i get a DHCP adress :S
but all normal download (http, update, mail) there is no loss of connection, even with high speeds (30Mbit).

but the further i come the more i like mac os X...

THANK YOU! You solved my issues!

Ditto, thanks a bunch.

where do i download the seatbelt.kext

How can I find out what kernel I have a I forgot

EDIT: Also which version of the combo update would you download and then extract the kext from? 10.5.5 or 10.5.6? Or it depends on your version right?


EDIT 2: My kernel is 9.2.0! How to I update to 9.5 or 9.6???!!?

Are you installing similar to what was described in my first post for the seatbelt.kext? Are you using the system.kext that is packaged with the voodoo kernel? What does it read when you get the KP?

Whoops sorry! I have an intel DG965WH Mobo. Everything works on my "mac" I have a PNY Nvidia 9800GTX+ and a E6400 CPU. I have 3 gigs ram anything else? Also I am on 10.5.6 and I updated my kernel to voodoo 9.6...Would I just proceed with your steps now?

For those in need of a quick workaround - for example to install Pacifist - you can open the .dmg in Apple's Disk Utility and convert it to a CD image, then it'll mount without crashing.

Disclaimer: I'm not sure if you need to have Toast installed for the conversion options to appear in Disk Utility.

WORKED PERFECTLY!!!

thanx a lot!!

Hello i'm new here, but i did manage to install os x 10.5.6 and got everything working. However, i couldn't install any programs in os x. I've tried installing iwork 09 and it gets stuck on the 1st step (i know this isn't related to DMG mounting issues). i have no problem mounting the dmg, but i cannot install any .pkg files; i can open them but it gets stuck right afterwards. and i have no problem opening .app files. plz help.

edit: in the attachment i can see a screenshot of the NTFS for Mac OS X installer, but i couldn't click on the continue button.

Is the GSoD related to this? A kernel panic is when the system freezes and spits out an error message on the left of the screen right? All I get when I try to run dmg files is the box that pops up and says the computer is dead and i need to shut it down.

I have 9.6 Kernel and am using the 10.5.6 Kext from the combo update but dmgs still crash my computer at the point when they are getting mounted.

yip that's kernel panic i think it's mostly related to chipset drivers.

I did all the above since I had problem with kernel panic when I was trying to mount a *.dmg file.
when I did the reboot I typed in "reboot [-f]" and the system restarted.. however, when it was about to start up I got the following:



sooo.. now I cant start the system.
How should I solve the problem?

thanks in advance : )


hmm... I restarted the system now and got the option to chose boot options, and I chose -v and now all of a sudden it works.. strange.. well I hope it will work when I reboot as well : >

I still get the error I was talking about before, but now I get the option to chose boot options and then it starts. How can I fix so that I dont have to chose boot options each time I restart the system?

u can get com.apple.Boot.plist from someone. i would try copying it from ur installation DVD and set permissions.

I installed iatkos5i and after installing all updates including 10.5.6 my usb thumb driver won't mount anymore, my external hard drive won't work either and I have already fixed the mounting problem - USB works for other things (keyboard/mouse). Now if I reboot the computer while both of them are still plugged in everything works fine. Any ideas???? Thank you very much!

Can anyone tell me where to download a kernel?

i have got the same question
how can i update the kernel from 9.4.0 (iPC 10.5.6)

Extract kernel from install DVD with Pacifist.

Install Kernel with OSX86Tools.

Don't forget system.kext version must match kernel version.

Hi thanks for all your help about the DMG mounting issue,

I knew this before installing so I backup my system and seatbelt then copied after installing however it's still not working. I downloaded 10.5.5 from the link you provided then follow your instructions precisely still no go.

Please help get this thing running This is my third fresh install due to the same problem.

Ps: That only happens with a few DMGs, like my iLife 09 dmg mounts fine but my xtorrent1.1 does not work and yes I've tried that same file on my macbook and fine there.


here is my kernel info:

So your are getting the Kernel Panic that references seatbelt?

Open Finder to the /System/Library/Extensions/ folder right click on seatbelt.kext and select "Show Package Contents" Open the Contents folder and then open version.plist in a text editor. What does it say for build version.

hy.
but what is the sense of your suggestion?
if I have a 10.5.6 retail setup .. I still have seatbelt 10.5.6. .. so why shall I replace with yours?

thanks

may I solve usb mounting pen drive problems? (now the only issue is that they're not visible.. nowhere in the system)

Try running or re-installing Voodoo 9.5.0......use the .dmg installer from here......since from Voodoo 9.5.0 User Documentation:

no panic just a warning popup then I click ok and nothing happens again some dmg mount fine see the attached image. Here is a copy of my extension folder including my extension.mkext http://69.108.218.45/wip/

Open terminal and type: If your kernel is 9.5.0 (Kernel version from 10.5.5) then you will need to do one of the following

1. install seatbelt.kext from 10.5.5

2. install kernel 9.6.0 (kernel version from 10.5.6)




Just like with the above issue you must have the system.kext match versions with your kernel. So if you checked your kernel and it is 9.5.0 you will need the system.kext from 10.5.5 which is also version 9.5.0. This is not to say that you don't have other issues related to your chipset but it is a common problem. If you have a USB drive plugged in before you start the computer and it works fine then this is probably the problem.

So to recap both seatbelt.kext, system.kext and your mach_kernel must mesh. You see this because people are not using the vanilla kernel.

OSX 10.5.6 - Kernel version 9.6.0 - System.kext 9.6.0 - Seatbelt.kext from 10.5.6 (build 45)

OSX 10.5.5 - Kernel version 9.5.0 - System.kext 9.5.0 - Seatbelt.kext from 10.5.5 (build 14)




It may be something else as it should give you an immediate KP. Let me look around if I come across something Ill let you know.

Why have you got multiple injector kexts installed.....NVkush, Natit and Titan......?

Hello.

I'm not good at english, but here is mt trouble.
When i mount DMG, i get the grey screen ( hold power down ) except if i mount dmg from a backup dvd.

is that the same on this thread ?

I'm on 9.4.0 Darwin Kernel
but in the 1st message, you talk about 9.5 and 9.6, what should i do ?

regards, bakk

Okay. How should i do that ? manually install newer kernel ?

regards

edit :

I installed seatbelt with osx86tools, and all is fine now. Thanks

PERFECT
thanks!!
ugo

that is a good question because when I installed just titan it then gave me only one resolution I think it was 1024x798 so I kept trying and when I selected those three my display works perfectly. I got a Geforce 9500 GT PCI-E

That kind of thing generally causes problems but if your not having problems there is no reason to worry. Most likely it is one of those three that is doing the job.

Are there any other DMGs you get this issue with? Try downloading Firefox and opening it. It doesn't look like a seatbelt issue but im still curious.

firefox worked fine! I copied the two to the server root dir (http://69.108.218.45) see if you can mount the xtorrent dmg on your intel machine. I tried a million times on my macbook no problem what so ever.

Ps: About the graphics card should I remove one then reboot to find out which one it is or leave it alone?

thank you for your help

I wouldnt worry about the graphics drivers. If its not broke don't fix it.

weird fetch is not working either anyway it's on the server too if anyone want to try it. Thanks

I have the 9.6.0 kernel and seatbelt from 10.5.6 installed, but I still get kernel panics when I try to mount any DMG or ISO.

Specs:
GIGABYTE GA-EP35-DS3R LGA 775 Intel P35 (set to AHCI mode)
MSI Nvidia GT 8800
Intel 2.66 Core 2 Duo

Also, I get the 'mouse lags when iTunes is open' error. Any idea on how to fix either of these?

Here is the fix for the mouse lag problem.
http://www.insanelymac.com/forum/index.php...2056&st=120
I am having problems with my kernel too... the clock is running too fast. Weird. I'm on voodoo 9.5.0 with an old version of seatbelt.kext.
What 9.6.0 kernel are you using?

Thanks! That fixed the mouse issue! When I uname -a I get:
Darwin TehFatBatzOSX.local 9.6.0 Darwin Kernel Version 9.6.0: Mon Nov 24 17:37:00 PST 2008; root:xnu-1228.9.59~1/RELEASE_I386 i386

I updated with the 10.5.6 Combo Update, running Vanilla Kernel and PC_EFI v9.

OK, Im still lost.

Others haved asked with no response, but I have kernel version 9.4 (iPC). Where can I get either the latest kernel or the necessary kext. You only have the kext for versions 9.5 and 9.6. I don't have a retail version of 10.5, I do have one for 10.2 .

Any suggestions would be great, I have OSX86 tools to install these changes. I think i understand how to set this all up, but I cant find the files.

Thanks,
Josh

Hi I installed leopardon my pc

Core 2 Duo E8400 @ 3.0 Ghz
Biostar TP35D2-A7
Corsair 2 Gb 667Mhz
Nvidia 8400GS 512Mb
ps/2 mouse & keyboard

using iPC OSx86 10.5.6 Universal DVD along default kernel and added seatbelt 10.5.5 patch
but it did crash on dmg mount
I did a uname -a I got


I installed the seatbelt.kext attached as



Then I tried osx86tools after a fresh install of leopard to install kext still crashed
Then I tried without the seatbelt.kext during install still crashed on dmg mount. Tried installing seatbelt.kext after it does not work please help

I have the same issue as you. No version of seatbelt.kext are working.

I have now solved the issue, I installed seatbelt.kext with kernel 9.6.0 using osx86tools
Thanks a lot to the makers
