Lightbulb *Updated 11/12* DMG mounting issues Sandbox.kext/Seatbelt.kext

DMG mounting issues & Sandbox.kext/Seatbelt.kext

* LAST EDIT November 25, 2012

The Problem
Kernel Panics, which happen during the mounting if Disk Images (.DMG), can be caused by not having the correct Sandbox.kext/seatbelt.kext matched with your kernel. You can correct the Disk Mounting issue by matching your kernel with the proper seatbelt.kext build. This is a common issue when working with non-vanilla kernels.

What are Sandbox.kext and Seatbelt.kext for?
Both are implementations of Sandbox described in more detailed here:http://en.wikipedia.org/wiki/Sandbox_(computer_security). Seatbelt was the code name used by Apple. This was used during 10.5 but was renamed Sandbox from 10.6 to present.

How to determine which versions you have installed
Check your kernel version by opening Terminal and typing:
Code:
uname -a
OSX 10.8 Mountain Lion
There is only one version of Sandbox.kext for Mountain Lion

OSX 10.6 Snow Leopard - 10.7 Lion
Check your version of Sandbox.kext
Code:
openssl sha1 /System/Library/Extensions/Sandbox.kext/Contents/MacOS/Sandbox
OSX 10.5 Leopard
Check your version of Seatbelt.kext
Code:
openssl sha1 /System/Library/Extensions/Seatbelt.kext/Contents/MacOS/Seatbelt
Compare the sha1 checksum, to the list above. In addition, Source Version and SHA1 checksums are provided at the end of this post.

The sha1 checksum is a hash created using a special algorithm. It results in a hash that is unique to a file. If a file is altered, it will not have an identical hash. Since a Kext is actually a folder, we must target a specific file within in order to generate the hash. For the Sandbox.kext, I chose the actual binaries.

Where do these files come from?
The files provided above were extracted from Apple's support site using Pacifist (Available here: http://www.charlessoft.com/)

Manual Installation
I prefer to manually install system related files. It helps reinforce your understanding of what files are for, where they should go, and what the proper permissions and ownerships should be set to. There are many applications that are available to do this for you. (Yes, you will find that some of these commands are redundant. Redundancy results in less questions)

In short:
Drag the downloaded Kext to your Desktop
(Replace "Sandbox" with "Seatbelt" depending on your needs.)

Code:
sudo -s
mkdir /backup/Sandbox
cd /System/Library
cp -R Extensions/Sandbox.kext /backup/Sandbox/Sandbox.kext
cp -R ~/Desktop/Sandbox.kext Extensions/Sandbox.kext
chmod -R 755 Extensions/
chown -R root:wheel Extensions/
touch Extensions/
rm -Rf Extensions.mkext
diskutil repairpermissions /
Reboot using the boot-flags -v -f

Steps explained:

1. Give yourself root privileges so that you can modify files.
Code:
sudo -s
2. Make a backup copy of your existing Kext. First we will make a directory called "backup" in our root directory and a directory in it called "sandbox" to store them. Open Terminal and type:
Code:
mkdir /backup/sandbox
3. Change directories to /System/Library This will shorten some of the commands we have to type in.
Code:
cd /System/Library
4. Copy Sandbox.kext to the new "backup" folder.
Code:
cp -R Extensions/Sandbox.kext /backup/Sandbox/Sandbox.kext
5. Copy the kext from your desktop to the extensions folder
Code:
cp -R ~/Desktop/seatbelt.kext Extensions/seatbelt.kext
6. Set the proper ownership for the extensions folder.
Code:
chown -R root:wheel Extensions
7. Set the proper permissions for the extensions folder.
Code:
chmod -R 755 Extensions
8. Touch the extensions folder
Code:
touch Extensions/
9. Remove the extensions cache to force OSX to rebuild it with our new kext.
Code:
rm -Rf Extensions.mkext
10. Repair permissions to your drive.
Code:
diskutil repairpermissions /
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.

This was really necessary. It seems people don't know how to use the search function.

Thanks leanceomni.

This should probably be placed with the rest of the [How-To] guides. I'll leave that up to you (since you are also a moderator ).

I agree... very well written.

I might place it there. I just posted it here and over on insanely as it seems, at least of there, that people post about this 12 times a day.

[EDIT] I wanted it to be visible in this part of the forum as you know people have the habit of getting tunnel vision and a fear of the search function if you catch my drift.

They made my post a sticky on insanely. If I see one more DMG mounting post over there Ill jump off a cliff

So doo I need to change my kernel first and then apply the seatbelt.kext?

I have 10.5.5 and installed voodoo 9.6.0

( I have the mounting issue)

So should I install voodoo 9.5.0 and then install the 10.5.5 seatbelt.kext?

If the 10.5.6 kernel works fine for you, you should update the kexts.

@oneshot

Did you mean you have Voodoo 9.5.0 or do you have a 9.6.0 derivative based on the Voodoo project. I know there are a few kernels out there based on Voodoo.

Basically if you are happy with your system and the only issue is DMG mounting then you will want to make sure your versions are meshing. Other than system.kext and seatbelt.kext, I do not know what other issues you may run into running a kernel that is ahead of the rest of your system. Ive only had experience running kernels older than the OS.

Just make sure that if you are running a 9.6.0 kernel you also have system.kext 9.6.0 & Seatbelt.kext from 10.5.6.

I have OSX version 10.5.5

I installed the kernal based on voodoo that is version 9.6.0

I looked online for voodoo 9.5.0 but it comes in a .DMG so I cant install it....
