This How-To is especially for those x201 where the standard installation fails. It seems that mainly the type 3680 of the x201 is affected. You will find the type on a sticker at the bottom of your x201.

 

If you have a 3680, putting the Framebuffer file AppleIntelHDGraphicsFB.kext into the E/E folder is probably not enough to get a bootable USB stick. Instead the following files can be used:

 

Unfortunately they have to be installed in the System/Library/Extensions folder, replacing the original files, and so things get a bit more complicated.

 

You need a running Mac OS X 10.6 or higher. Can be on a real Mac, a Hackintosh, or a VMWare image.

 

1.) Install Mavericks Installer on USB stick

- Plug-in the USB stick (>= 8 GB), HFS formatted

- Download myHack from http://myhack.sojugarden.com

- Download Mavericks Installer from Apple Store

- Launch myHack, select function "Create OS X Installer", select "Create OS X 10.9 Install Disk", select "Scan my System" and let myHack do it's main work.

- Please do NOT patch the installer for MBR support. myHack 3.3.1 does not support that correctly.

 

2.) Install graphic card extensions

- Download x201_Mav_SLE, attached to this post.

- Open the folder System / Library / Extensions (S/L/E) of the USB stick in the Finder.

- Delete all files beginning with "AppleIntelHDGraphics". Should be 4 files.

- Copy the content of the downloaded ZIP file into the extensions folder. 5 files.

- Open "Terminal" application (see "Applications" / "Utilities"). Execute the following commands: 

: cd /Volumes/<your_stick_name>/System/Library/Extensions

: sudo chmod -R 755 AppleIntelHDGraphics*

: sudo chown -R root:wheel AppleIntelHDGraphics*

: sudo xattr -rd com.apple.quarantine AppleIntelHDGraphics* 

- close "Terminal" application

 

3.) Install "Extras" folder

- Download "x201_Mav_E", attached to this post.

- Launch myHack, and select "Install Extra".

- Select your stick as the target.

- Select "Use My Own", and select the previously downloaded "x201_Mav_E" folder.

- myHack copies the folder onto the usb stick, adjusts the ownerships and permissions and regenerates the caches.

- The USB stick should be ready now to install Mavericks on a x201.

 

4.) Boot the installer stick

- Plug the stick into any USB slot of the x201.

- Turn on the x201

- Immediately press "F12"

- In the boot menu select your stick.

- Booting from the stick might take a bit longer with periods of inactivity - be patient.

 

5.) Install Mavericks

- Follow the installation, format the hard drive if necessary.

- At the end, myHack will pop up and ask for the Extra folder.

- Select "Use My Own" and select the "Extra" folder of your USB stick.

- answer "Yes", "Yes", "No" for removing problematic extensions.

 

6.) Copy SLE-Extensions folder from stick

- Don't boot from your hard drive, boot from the stick again

- Select language, but then don't follow the installation

- Instead launch the Terminal application

- Enter:

: cd /Volumes/<your_Hard_Drive>/System/Library

: mv Extensions Extensions.orig

: cp -R /System/Library/Extensions .

: exit

- Run myHack with function "myFix", select your HDD and select "Full".

- Reboot your x201 by using the Apple menu

- The post-installation process should start, and at it's end you should see the desktop.
