This part of the website is the first instalment of getting Snow Leopard to work on the VAIO VGN-N11M/W. Midway through you will move onto the installation of Snow Leopard, but this first step is required in order to make it work perfectly and with ease. Everything here is tested; I wonít publish anything on this website if it isnít tested by me beforehand. If something is being tested and causes the Mac to brick, I will begin using my own guide (this). And will update and make changes to the guide as I go along, hopefully allowing users who already have the system working (but donít want to reinstall) using another method. But sometimes this isnít possible, but I will try.

Required Downloads

Here are the files required to make your MacOS installation work. They will be marked when required.


Here is my setup, and one I recommend you use too. If you donít have this specific setup, donít worry. Just find a way to compensate for missing components (like external drives to USB disks).

  • Laptop: This is where Snow Leopard will be installed, and only Snow Leopard. You can still setup a dual boot with another OS, but you will need to know how to do this yourself I wonít be going over it. Mine hosts only MacOS Snow Leopard.
  • USB Drive: This is housing everything I need to modify my MacOS Leopard/Snow Leopard installation. (Kexts, plists, sound, video etc.)
  • External USB Drive: This is where Leopard will be installed. I will have other data on here too in separate partitions. As long as your Leopard partition is no smaller than 15GB, you will be fine. This is to update Leopard to 10.5.8. The reason why is simple; Leopard will be used whenever we need to alter and change any settings inside the Snow Leopard installation (ie. Kernel panics). It is also useful for running tasks like Drive Defrags using iDefrag. This will increase speed/reliability. You canít do the whole disk without using an external non-booted partition. The VAIO VGN-N11M/W supports external drive booting; you just need to enable this option inside BIOS. This will be outlined in the tutorial.
  • DVD-RW: This is to burn Leopard to, not Snow Leopard. Simply put. (I recommend you use ImgBurn for burning.)

BIOS Setup

Set up your BIOS. When you turn your laptop on, repeatedly hit F2 about 4 times. Once the BIOS has loaded follow these steps:

  • Enable ďExternal Drive BootĒ, under Advanced. Leave or enable Network Boot.
  • Disable the ďVAIO Animation LogoĒ Ė this just slows booting down.
  • Increase your sound to 8. Make the most of your speakers.
  • Move onto Boot unless you donít want to setup passwords for your computer. This is my current boot order. Iíd recommend this, though itís up to you. (I have network boot disabled).

    • Place ďUSB FlashĒ as #1.
    • Internal Optical Drive as option #2.
    • Internal Hard Disk Drive as #3.
    • Press x on any left over ones to remove these from the boot order, this increases boot times (nothing noticeable).
  • Exit setup, saving configuration settings. Close your CD drive and let the Leopard disk boot.


Just before installing Leopard, copy over the Snow Leopard.iso file you downloaded onto the other partition on your External USB HDD, you will need this later!).

Once you have booted the DVD of Leopard. Go to Disk Utility and erase your Snow Leopard partition (I have named mine Macintosh), also delete the partition on your external drive where you are installing Leopard (appropriately named Leopard). If your disk wonít show inside Disk Utility, keep it plugged in and restart your computer, rebooting from the DVD. Once you have done that, continue through the installation. Select Leopard as your destination. Click next, then customize. Select the following in each group:

Key: Italics: Represents parent directories / Bold: Option inside directory.

  • iATKOS v5i Main System
  • Bootloader > PC EFI V9
  • X86 Patches > Decrypters > AppleDecrypt
  • X86 Patches > SMBIOS drivers > SMBIOS Enablers > SMBIOS-EFI
  • X86 Patches > ACPI > x86 ACPI
  • X86 Patches > Disabler.kext
  • Drivers > VGA > Intel > GMA950 > GMA950 a
  • Drivers > System > SATA/IDE > Intel SATA


That is all you need to select, DO NOT select anything else otherwise you WILL have a failed installation. It may boot and work likr normal, but installing a Network driver for example will cause you to not have certain funcationality. The installation will take roughly 30 minutes (without disk checking). After the installation has completed restart your computer removing the DVD from the drive. Once your computer boots up for the first time, hit select under you see the "boot menu" but not too much otherwise you will cause your system to boot normally. Once Leopard boots follow the remaining steps to the tee. DON'T run software update yet!

Now it's time to install the OS. Just follow the installation screen to the end, take note of all fields. If you make a mistake on things like usernames, you can't change them. You will need to reinstall.

Finishing Touches

This section is for installation and modifiying drivers to make certain things work. Midway through this, there will be a branch off to install Snow Leopard - if you've already installed Snow Leopard through the tutorial I posted, then skip past and continue with the rest of the points.

  • Step one - Networking

  • Out of the box AirPort will work, but you won't have any Ethernet capabilities. In order to enable it, it requires a simple copy and page of the Info.plist file located at: /$USB/MacOSX/Kexts/IONetworkingFamily/Plugins/AppleYukon2/Info.plist You want to copy this file to the following location (once you reach the kexts, right click and select "Show Package Contents"): /$Leopard/System/Library/Extensions/IONetworkingFamily.kext/Contents/PlugIns/AppleYukon2.kext/Contents/Info.plist - Drag and drop the Info.plist on the USB, click Authenticate, Replace, and enter your password. Now you will want to reboot your computer. (Pull out the USB stick before rebooting). Once you boot, hit Esc again until you see boot menu. Once you see Darwin bootloader, hit tab and enter "-f -v" (With spaces between, no quotes) and hit enter. Wait for it to boot. Then once you login, go to System Preferences > Network - You will see Ethernet saying "Connected".

    If you get any errors about this kext not being installed correctly, navigate to /$Leopard/System/Library/Extensions/, locate the IONetworkingFamily.kext copy and paste this to the desktop, then place it inside the Kext Installer app and run the installer, then reboot.

  • Step two - Sound

  • By default you will have working sound. But you won't have working output from headphones. The headphone jack isn't reconized by default. This takes a few seconds to fix. Open the USB stick up and navigate to: /$USB/MacOSX/Sound/ALC262.txt - Copy and paste this to your desktop. Now go to: /$USB/MacOSX/Installers/ - Copy and paste to your desktop (click continue and authenticate). Now drag and drop ALC262.txt over the Authenticate, give it a few seconds, click quit. You can restart if you want. But it isn't forced.

  • Step three - Graphics

  • This is very straight forward. Navigate to /$USB/MacOSX/Kexts/. Copy and paste all apart from IONetworkingFamily folder to your desktop. Navigate back to /$USB/MacOSX/Installers/Kext and copy and paste it to your desktop. Open the app. Drag and drop the selected kexts into the window, enter your password and press "Easy Install" - then OK. When prompted, reboot. Not forgetting to remove the USB stick and pressing Esc to get the boot menu, follow the same steps as before. Press tab and enter "-f -v" into the window. Wait for it to boot.

  • Mouse/Keyboard

  • The keyboard installation precedure can be viewed inside the Snow Leopard installation guide, however the mouse alters a little differently.

    • Using the first step, run the ALPS Glidepad package and complete the installation.
    • On the next boot you will be given the option to fix FFScroll, ignore it and choose decide later.
    • Locate and find the FFScroll folder here: /$Leopard/Library/StartupItems/FFScroll. Delete this folder.
    • Next go to System Preferences > Accounts > Login Options > Click +.
    • Hold down Command, Shift and G and enter into the little box: "/usr/local/bin/" then select "FFScrollDaemon" and click Add. Tick the "hide" option. (If the daemon doesn't exist, download it from the download list and copy it there.)
    • Exactly like Snow Leopard you will have a Terminal window open everytime you login, this is FFScrollDaemon opening. Just quit Terminal afterwards.

    • Additional Info: I have found a PrefPane addon which will allow you to change your mouse speed, for both Trackpad and Mouse. Download the Mouse Acceleration ZIP file (from the developers website), install it, done.
  • Step four - Snow Leopard

  • This is where we install Snow Leopard. If you took my advice and copied the Snow Leopard ISO onto your other partitions on your External HDD, then just mouth it. Once it mounts, on the menu bar under Finder, click Go > Go To Folder.... Enter the following into the box (When entering the Volume name, just enter the first few characters, MacOS will enter the rest for you): /Volumes/Snow_Leo.../System/Installation/Packages/. Locate a file called OSInstall.mpgk, open it by double clicking. Go through the options, and change the destination to Macintosh. Then click Customize and like before with Leopard, enter these specific values.

    • Mac_OS_X_10.6.1
    • Mac_OS_X_10.6.2
    • Boot_Loaders_Intel_Only > Chameleon_RC3_PCEFI_10.5
    • Audio_Drivers > ALC662
    • Laptop_Support > AppleACPIBatteryManager
    • System_Support > CMOS_Reset_Fix > ElliottForceLegacyRTC
    • System_Support > SATA_ATA_Fix > AHCI_SATA_Fix
    • System_Support > Fakesmc_V1.0
    • Additional Fonts
    • X11
    • Rosetta

    Installation will take roughly 20 minutes, usually faster depending on your hardware (Hard drive speed). After the installation completes, DON'T RESTART, we have yet to change things inside the OS which we will do inside Leopard.

  • Enabling root user

  • This step isn't required, but it's helpful if you ever find yourself needing it.

    Go to System Preferences > Accounts > Login Options > Network Account Server - Join... > Open Directory Utility... > (In the menu bar under) Edit > Enable Root user - Complete the fields for your password. DON'T SET THIS AS YOUR USER PASSWORD!

    Next Chapter: Setting up Snow Leopard

Updating Leopard

Only continue this step after you have completed the Snow Leopard installation - Open up Software Update under the Apple menu and wait for it to find downloads. The one we want more importantly is the 10.5.8 Combo update of 768MB. Download the updates and then reboot.

After you have installed the Leopard updates, login to Snow Leopard, copy and paste all the graphic kexts from "/$USB/MacOSX/" to "/$Leopard/System/Library/Extensions/" then reboot. When rebooted, on the boot loader press tab twice, select the Leopard partition and enter "-f -v" on the boot flags. Once booted up, follow step one, two and three from the start.
