OS X Snow Leopard installation on Dell Inspiron 1520

You will need:

• Dell Inspiron 1520 (preferably a Core 2 Duo with NVIDIA 8600GT)

• OS X Snow Leopard Retail DVD

• iBoot (http://tonymacx86.blogspot.com)

• MultiBeast 3.7 (http://tonymacx86.blogspot.com).
  I was having kernel panic issues with v3.8.

• Kext Utility

Drivers (kexts) and other required files:

• AppleACPIPS2Nub.kext, ApplePS2Controller.kext, AppleBCM440XEthernet.kext, FakeSMC.kext, FakeSTAC9205.kext, LidSleep.kext, VoodooBattery.kext, VoodooHDA.kext, VoodooPowerMini.kext, VoodooSDHC.kext

• DSDT.aml, smbios.plist, com.apple.Boot.plist

Download all files here

BIOS Settings:

Under SATA option, select AHCI mode.

Installation Steps:

• Boot from iBoot and on the
  selection screen swap the DVD with OS/X Retail. Press F5 to refresh
  and select Mac OS/X Installation. You should now see a grey screen
  with an Apple logo. If everything goes well you will see the
  language selection screen.

• From the Menu, Select Utilities -> Disk Utility,
  

  • Select your hard drive from the left pane and click on 'Partition'.
    

  • Click 'Options' at the bottom and select 'GUID Partition Table'.
    

  • Select 'Mac OS Extended (Journaled)' from Format drop-down options.

  • Finally, click Apply.

• Close Disk Manager and continue with the installation. This will take around 30 minutes to complete.

First Boot:

• Upon reboot, swap the DVD with the iBoot and boot from it. This is because there is no boot loader currently installed on the HD.

• When presented with the selection screen, select OS X (or whatever you named your OS/X partition).
  

• This will boot OS/X for the first time and you will be presented with Initial setup screen. You can skip the registration screen and continue to the account creation. Once done, you will log into OS/X.
  

• Run MultiBeast and select the following options:

Drivers & Bootloaders -> Bootloaders -> Chimera v1.4.1 r877

• Unzip the downloaded file (above) and copy SLE folder contents to /System/Library/Extensions folder.

If using terminal, the command will be:

sudo cp -R SLE /System/Library/Extensions

• Now copy the contents of the Extra folder from the zip file to /Extra

sudo mkdir /Extra
sudo cp -R Extra /Extra

• Run Kext Utility and it will fix any permission issues.
  

• Reboot using HD and it should boot up fine.

Now you have a fully functional OS/X 10.6.3

You can download the 10.6.7 combo upgrade to upgrade your OS/X. Every time you upgrade, you will need to copy the drivers (kext files) in /System/Library/Extensions folder and run Kext Utitlity.
