How to Install Snow Leopard on Mac OS X OSx86


Snow Leopard has arrived and we all know how Necessary is it so that you can improve. The
pleasure of the OSx86 has risen to ranges the place one and all must run the
newest MAC OS X and Snow Leopard is however evident.

Sooner than you begin – You will have to have an present OSx86 working.

Within the following tutorial we can convey you ways can that you could EASILY
Set up the newest Snow Leopard (construct 10A432 GM unencumber, the Retail
model) for your PC which has current MAC OS X 10.x.x working.

Lot’s of web sites had been consulted to arrange this information. Different because of
Technojunkies,  iHackintosh, InsanelyMac. This guide might not be perfect yet (no guide is
perfect, yet) but i`ll try my best to improve it within few days, meanwhile if
you face any issues, leave your comments, I`ll try to solve any issues that you
might come across.)

We need two disks. Why ? – Snow Leopard needs a Leopard Install —
One HDD with Leopard already installed and Second hard disk for Snow
Leopard. UPDATE: Now, you can use Flash Drive too (8GB)

Before you begin, download the pre-requisites –

  1. Tools –  MediaFire RapidShare
  2. Kexts –  MediaFire RapidShare
  3. Chameleon 2.0 + EFI 10 –  MediaFire RapidShare
  4. Chameleon 1.0 + EFI 10 –  MediaFire RapidShare
  5. Misc. –  MediaFire RapidShare
  6. Mac OS X 10.6 Snow leopard Retail build 10A432 (As ususal, we won’t post
    links, google it)

Let’s Roll

Step 1. Preparing the New Disk

Make sure you have connected your second “New” Hard Disk or Flash Drive.

Boot into Leopard, launch Disk Utility from Spotlight. Partition your New
disk with GUID partition scheme. Name the partition  e.g. “New”. Now set
yourself as the owner by running the following at drive’s Root.

sudo –s

chown 0:0 /Volumes/New

For USB only – Once you’ve formatted your USB disk as MacOS Extended
(Journal) , head over Restore section and drag MacOS X Install DVD in the source
column and your USB stick to destination and make sure you uncheck erase
destination. Right click your USB stick and select Get Info. Do make sure that
“Ignore ownership” for this device is unchecked. If you’re having issues with
permission, later on, do check this back.

Step2. Installing DMG

Now, Mount the Snow Leopard DMG File.

Next, Installer window will pop-up, click on the free space anywhere in
window and press key sequence - CMD + Shift + G . A small
window will appear on top of the existing window. Here, type “Mac OS X Install
DVD/System/Installation/Packages/”, and Go.

In the next window, locate the “OSInstall.mpkgand double
click this package file to start Snow leopard Installation.

Note– Default “OSInstall.mpkg” works for GUID partitioned drive
only. If you need to install on MBR, then google for Modified OSInstall.mpkg for
MBR, download modified one and replace with default one.

Step 3. Customizing Install

Go through the options and select your New drive. De-select all the stuff you
don’t need like Printers, Languages, etc.. and wait for it to finish. It should
take 5-10 minutes.

After its done installing, Don’t Reboot!

Now step 4. and onwards, we will install Bootloader and some important
drivers (KExts), Patch DSDT and Install certain important system files, so, bear
it with me.

Step 4. Installing BootLoader –

Unzip the Chameleon Bootloader, Install the “Chameleon-2-1.0 r431.pkg  and then “Chameleon v2 Snow Leopard Support.pkg to the New Drive

Note – If Snow Support Package Shows an Error, Then Follow 

Step 5.

IMPORTANT – If Chameleon 2.0  gives you Kernel
Panics then try reinstalling with Chameleon 1.0

Step 5. If you are using PCEFI bootloader on your existing
OSx86 system then “Chameleon v2 Snow Leopard Support.pkg” will NOT
serve the purpose.

In this case, you have two options:

Option 1. Either install the Chameleon-2-1.0-r431.pkg”
over your current 10.5.x Installation then reboot and do the process
again (from Step 1). or

Option 2. Launch
the “ShowAllFiles (included in “Tools”) and click Show. Then
Navigate to the root of your  New Drive and delete the “boot” file you see  and
replace it with the boot file included System Downloads. After replacing the
boot file again launch the “ShowAllFiles and click Hide.
Continue to Step 6.

Step 6. Patching  DSDT –

From the downloaded Tools, Open the DSDT Patcher. Select
“Darwin/Mac OS X” in Operating System, then select DSDT Patch in options and
before hitting the Run DSDT Patcher button make sure to change the destination
to “New” Drive.

Step 7. Installing KExts (Drivers)-

this assumes that you had downloaded all Kexts that might be needed for your
system’s compatiblity. Place all the “kext filesin
 ”/New/Extra/Extensions”, and copy the Extensions folder in Extra to the
desktop, and drag it to “Kext Utility. “Kext utility” will
actually repair your permission and generate a new
Extension.mkext. Now, Move the Extensions folder and the
extension.mkext back to “/Snow/Extra

Step 8. Configuring boot.plist with

Launch EFiStudio and look for your Display/Video Card
through the drop down menu. Click add device and you will see some  numbers,
copy them.

Add the following XML to your in

<key>Graphics Mode</key>
<string>–number you got with

Save and Exit. Put the SMBios.plist into /New/Extra.

Update: Step 9

Step 9. If you added any driver
kext to /New/System/Library/Extension, This step will rebuild
the Extensions.mkext cache while booted in Snow Leopard. Reboot and go to Single
User mode by typing the flag -x32 –s

Type the following commands:

/sbin/fsck -fy
/sbin/mnt -uw /
kextcache -v 1 -t -m

Now Reboot and Fall in Love with the Snow Leopard –

Basic Troubleshooting Guide

As promised, I added this section to give out better troubleshooting in case
of any issues you might have come across.

For those who are getting Kernel Panics try to
boot in 32 bit Mode + Safe mode using following Boot flag.

-x32 –v –x

Kernel Panic (IOATAFamily.kext) – Go to your New HDD ,
navigate it through /System/Library/Extensions and delete IOATAFamily.kext or
simply replace IOATAFamily.kext with a patched kext from your Leopard
installation or from netkas. If that fails , simply delete this kext. You’ll
lose ATA support , however it would still install on your SATA drives. Just make
sure its set to AHCI instead of IDE

Generic Kernel Panic on CPU – This problem is related with Chameleon V2. Its
recommended for you to use PC_EFI v9 with a patched boot file.
Panic (generic CPU error)
– It occurs if you have an Atom processor or
some of the very old boards. The only way to fix it by using PC_EFI v9. Its kind
of simple to do , all you have to do is download this installer and boot file
for Snow Leopard. Its bit old school. To do this firstly , you’ll have to
download PC_EFI v9 installer and this boot file from
it. Install this boot loader to your USB Drive (be sure to change its
destination) and replace the boot file with this patched file. Be sure to follow
rest of the guide such as generating extensions.mkext and so on and so forth.
Its just that instead of Chameleon , you’ll have to use PC_EFI v9.

Another thing which I’ve noticed that it occurs when you do a -f. I think its
related to permissions of the kext. Do refer to the guide up on how to generate
extensions.mkext for both /Extra and /System/Library/Extensions and how to fix

Reboot loop – It clearly means your processor is not
supported for instance if you’re like me , still on a Pentium D. For this you’ll
have to grab a patched mach_kernel.

CMOS Bug – If you get an error on BIOS after you’ve
installed Snow Leopard (this includes BIOS settings have changed or other
strange BIOS errors) This is a known issue and it requires your DSDT to be
patched. Again you can check out the guide below which I’ve included on how to
fix it

Fix Permission Error in Disk Utility. This is caused
when Snow Leopard is installed from Leopard.

Disk Utility Permission fix error – If you get this error in
Disk Utility , “ No Installer packages can be found for this disk” whenever you
want to verify permission and fix permission. This is caused when you run Snow
Leopard installer within Leopard itself. Its a simple fix. You’ll have to re-run
BSD.pkg , it could be found in /Volumes/Mac OS X Install
DVD/System/Installation/Packages or /Volumes/OSX86/System/Installation/Packages
. Just run it and voila it should be fixed ! Now you can use Disk Utility to
repair permissions !

UPDATE 2. More Troubleshooting Tips

  1. If  you are stuck on Waiting for DSMOS then simply delete the DSMOS kext in
    Snow/Extra/Extensions but make sure you must have FakeSMC kext.
  2. If you are stuck on RTL8169E error: Disable Hardware LAN in your BIOS and
    boot again. I’m making a list of it, so stick with us.
  3. If you have an IDE drive or your laptop contains IDE drive then Install AppleIntelPIIXATA.kext by Netkas
    to make your ATA/IDE work in Snow Leopard. This kext is useful for ICH6/7/8/9/10
    with ahci disabled and for lappies too. This kext also helps IOATAFamily related
    error causing Kernel Panic.

UPDATE 3: Replacing MACH_KERNEL (for Pentium D, Celeron,

Replacing mach_kernel with a patched
mach_kernel (required for Intel Pentium D/Celeron D/Pentium 4 with SSE3 or AMD
processors with SSE3)

By default , vanilla kernel will not work on these processors , its because
its not based on Intel Core micro-architecture series. Thus resulting a reboot.
To fix this modbin has bin-patched (aka binary patched) the Vanilla kernel , so
that it doesn’t perform any checks on CPU type. So it would boot on all CPUs
regardless if its AMD or Intel. Keep in mind that. You may grab the patched
kernel from here (for Intel
Pentium D/Pentium 4 with SSE3/Celeron D with SSE3) and if you’re using AMD
kernel , grab test7 by

For SSE2 support , you’ll have to wait till Apple releases the source code
to kernel and wait for someone to patch it and make it available for SSE2 users.
This goes the same for AMD users and Intel Pentium 4/D users with 64-bit support
, as it has to be patched to enable 64-bit support on these processors. For AMD
users , there is a special guide , alternatively do scroll below and read. You’ll
have to patch binaries (CPUID fix). However , even if there is SSE2 support for
Snow Leopard’s patched kernel , its going to be very slow on your pentium 4/M
with SSE2. Its highly not recommended to upgrade if you’re still on a Pentium
4/M , not to mention that Apple has dropped legacy support from Tiger and
leopard , that may not allow older Pentium M (laptops) and Pentium 4 (Desktops)
to work  !

UPDATE 4. Install on AMD (64×2, others)

The base procedure remains the same, all you have to do instead is use
Chameleon rc 2.640 pkg. and PCEFI V10, DSDT patch, Some kexts and Modbin
