I have installed retail SL OSX on SONY VGN-CR120E with success. It's a working , but not perfect hackintosh computer. It serves the purpose of running osx-specific applications when you need it. Here are the steps which may help you to install SL OSX on this SONY notebook:

Installation of SLOSX on SONY VGN-CR120E
What you need to have in hand:
1. Purchase retail OSX DVD from Apple.
2. Download Multibeast from “http://tonymacx86.blogspot.com/2010/...-os-x-on.html”.
3. Download VoodooHDA.kext from “http://code.google.com/p/voodoohda/d...ooHDA.kext.zip”.
4. Download PowerManager from “http://www.insanelymac.com/forum/ind...=post&id=36993”.
5. Download GMA 4500 package from “GMAX4500 - Downloads - Kexts.com.
6. USB-mouse and USB-keyboard.
Hardware components:
SONY VGN-CR120E
BIOS ver. R0231Q0
4GB ram
Internal 160GB SATA HD
T7100 CPU
Realtek RTL8101 PCI-E Gigabit NIC

Installation of OSX 10.6.0
(A) On a MAC or Hackintosh computer:
1. Use a working MAC computer to prepare a USB drive of “SLOSX Installer” from retail SLOSX DVD
a. Plug USB drive into one of USB port. Partition it with GUID and formatted as MAC journaled.
b. Install “SLOSX Installer” to this USB drive by selecting “restore” under Disk Utility. Use retail OSX DVD as the source and USB drive as the target. When restoration is completed, start “Multibeast” and only select “Easybeast” to install boot loader onto this USB drive. At the meantime, also copy “Multibeast” to the USB drive.
(B) On SONY VGN-CR120E:
Since there are 3 USB ports present in this note book, only one will be available for either USB-mouse or USB-keyboard when OSX Installer and external USB-HD are both plugged in at the same time. However, you can swap mouse and keyboard back and forth during the initial installation process.

2. Boot computer from the USB drive which you just prepared as above by pressing “Esc” as soon as “SONY’ boot logo shows up during booting and select USB drive to start. Also have your external USB-mouse and keyboard connected to USB ports at the boot.
3. Use “Disk Utilities” to partition HD as GUID and format it as MAC journal format. Select it to install OSX until the end.
4. Reboot computer from USB drive as step (2). Press any key and select the internal hard disk which you just installed OSX (step 3) to start the system instead from USB drive. Continue to finish last stage of installation. At this time, you can swap mouse and keyboard back and forth during this installation process. VERY IMPORTANT: DO NOT REBOOT COMPUTER AT THE END WHEN THE LAST STAGE OF INSTALLATION IS COMPLETED!!!
5. At the end of installation prior to rebooting the computer, start “Finder” and go to “/System/Library/Extensions/” folder to delete the following extensions:
AppleIntelGMAX3100.kext AppleIntelGMAX3100FB.kext
AppleIntelGMAX3100GA.plugin AppleIntelGMAX3100GLDriver.bundle
AppleIntelGMAX3100VADriver.bundle
6. Start to install “GMAX4500.pkg” which you downloaded earlier.
7. Once installation is completed, continue to run “Multibeast” and select following items to install to the hard disk:
a) Easybeast: to install boot loader
b) System Utilities
c) “Voodoo PS/2 Controller with Trackpad Support” under “Advanced Options-> Kexts-> Miscellaneous->”
8. Now, you can reboot computer when finish step (5)-(7). This would be your 3rd rebooting process.
9. Start booting computer without USB drive. Run kext utility such as “Kext Helper b7” to install following extensions:
AppleACPIBatteryManager.kext: to show battery indicator
VoodooHDA.kext: for audio
10. By this time, you should have a working SONY CR120E with SLOSX 10.6.0.
Note: DO NOT change display resolution (1024x768) yet.
11. Download 10.6.6 combo update from APPLE and install it to your SLOSX10.6.0 as usual. DO NOT REBOOT COMPUTER AFTER UPDATE!!!
12. Go to “/System/Library/Extensions/” and delete the following extensions:
AppleIntelGMAX3100.kext AppleIntelGMAX3100FB.kext
13. Reinstall “GMAX4500.pkg” as step (6) and reboot computer. Your system will return to 1024x768 resolutions.
14. Go to “\Extra” folder and edit file “com.apple.Boot.plist” by adding these two lines ahead of “<key>TimeOut</key>” line:
<key>Graphics Mode</key>
<string>1280x800x32</string>
15. One additional adjustment:
a. Check “Clicking”, but not “Dragging” under “System Preferences-> Trackpad” so that trackpad will function normally.

What are not working:
1. Wireless: built-in Intel wireless 4965 controller does not work. Use USB-WLAN from “Airlink 101-AWLL6075” instead.
2. WebCam: built-in WebCam does not work.
3. “Shut Down” under “Apple” menu works as “Restart” instead.

Hi,

I am trying to get this working on my vgn-cr120e. After I restore the disk image to the USB and install easybeast and multibeast to it, I am unable to boot the vaio from the usb. I simply get a blinking cursor on the top left of a blank black screen.

Any ideas what I'm doing wrong, or where to go from here?

Thanks,
Kurt
