I'm adding the code to the dsdt right now. I'll let you know what happens. Thanks for the help.

The USB situation is fixed. Thank you. I still can't seem to figure out the dimmer yet.

I solved the boot loader problem by simply downloading the Chameleon Preference Pane and changing the first boot from "Mac OS X" to "System Reserved" which is the Windows 7 boot manager. Windows Update works perfectly so far.

Two problems left:

1.) The dsdt file fixed the USB problem at the expense of the trackpoint. I have not found a fix for it yet.

2.) I still can't get the dimmer to work. Is there a program or kext download I can use to fix this?

Nice solution.


The trackpoint should not have anything to do with the USB fix. Make sure you are using the correct kext and use "myfix" to regenerate kext cache and fix permissions, then restart.


By saying "dimmer" I suppose you mean the brightness slider. Then just add the following code before Device(LNKA) in your dsdt.

I used a generic trackpoint kext that fixed the trackpoint problem. I had not downloaded the brightness slider and that was my only problem. Your dsdt fixes worked flawlessly.

Thanks so much for your help as well as patience with a hackintosh noob. Now my hack works perfectly. You're a beast!

Could you post a copy of your Keymap4Macbook preferences? I can't figure out how to map the Ampersand key correctly in order to install sleepwatcher.

Here's my KeyMap4Macbook setting. Basically, I just need to remap for the backquote (`) key so that I can type ` and ~. I don't have any problem with the Ampersand key though.

pff i am working a week to get osx on the x220. i don't get it.

Do i have to have Snow Leopard to follow this tutorial ? because i follow the first step but its not clear...do i already need to have snow leopard on x220 ??

Yes, you need to have OS X running, either another hackintosh or in a virtual machine, in order to do this install. It doesn't have to be on the x220 first.

i have a pc with osx lion(vmware) but it really sucks..i want native osx native (better for performace)

first of all i dont have a external cd (x220 does not have a cd) so i am trying to do everything from a external HD (USB)

1) what did you guys change in the bios ?
2) if i follow this tutorial on my pc (osx) and create a external usb hd with all the steps i end up with a full instal for osx lion WITHOUT having any osx on the laptop now, right ?
3)some people say you have the usb to MBR to be seen but in the tutorial it stays GUID..
4)also check this, in the tutorial it says: " 2.Install Chameleon on both the partition you made and your snow partition", I don't have a snow partition so wtf ?
i can't do step 7 because i don't have any of that stuff... skipped that..

//

the first part of the tutorial sucks, its not consistent and confusing.
i followed every detail but i ended up with a clean laptop = no osx / no windows.


going to try tomorrow again.

I had another question. Were you able to change your LCD screen resolution to 1366x768?

The obvious question is now - has anyone updated to 10.7.4? Please share your experiences.

everything works now except the sleep mode but i will fix that soon enough.
got some simple questions..


1) do you really buy new wifi cards or do you change the bios setting alone ?

2) i got 1.28 flash bios, i download the file and use winflash and pinpoint: FvRecovery.fd to flash but it gives me an error: "Please select a correct BIOS image"...am i doing it wrong or what ?



PS: for the guys that have trouble, i had 10.7.3 LION and this tutorial has allot of files with 10.7.2 and 10.7.1 files (OSInstal especially!!)

I have updated to 10.7.4. However, AppleIntelCPUPowerManagement.kext consistently causes KP. I have tried a couple of different versions, without any luck. Now I have to use NullCPUPowerManagement.kext temporally.

One interesting thing I noticed is that, after updating to 10.7.4 the Ricoh card reader suddenly start working with this version of VoodooSDHC.kext.

So if we can find a working AppleIntelCPUPowerManagement.kext, I think we'll make x220 a 100% working hackintosh.

can someone with x220 upload their latest /Extra map ? and Extra/Extensions map ?

Did you lose the ability to put the computer to sleep after the update? I had it working in 10.7.3, but now my system just restarts when I try, both manually and when I close the lid.

Can someone answer the questions ???

Do I need another wifi or something like that ? Because I am trying to whitelist but the image is not accepted 1.28 ?

Yes, I have exactly the same scenario.

If you want to buy a Mac OSX supported wifi card to replace the original one, you have to flash the hacked bios that removes the whitelist; or the system will not boot (Laptops do not allow arbitrary wifi cards to be installed in the system).

If you want to use a USB wireless adapter instead, you don't need to worry about the bios at all.

I managed to get AppleIntelCPUPowerManagement.kext on 10.7.4 working, so that sleep and speed stepping work again. (I have updated my post as well.)

It requires 3 steps:
1) Patch AppleIntelCPUPowerManagement.kext.
The script and instructions can be found here.
You can also download the my patched AppleIntelCPUPowerManagement.kext, and install it in /S/L/E/
2) Add “DropSSDT=yes” to org.chameleon.Boot.plist
My org.chameleon.Boot.plist is enclosed.
3) Create or find a SSDT.aml for your processor and put it in /Extra/, along with your DSDT.aml
Here is the ssdt.aml for Intel i5-2410M.

Remove NullCPUPowerManagement.kext, if you have it installed; then fix permissions, regenerate kextcache, and restart.

Hello,

thanks a lot peroxide for all what you have done !!!!!!!!!!
This guide is pretty well done and I can't wait to start it, I am just waiting for a new bigger hard drive.
I am currently reviewing the steps and preparing the latest files,but I cannot find on the web a SSDT file for the 2520M.
Do you know where I can find that ?
alternatively you said "create", do you know how I can create one ?

I have one more question what are klibc.dylib and uClibcxx.dylib files ?
thanks again

I need some help clearing a few thing up.

First, WiFi: If I use the whitelisted bios will the standard WiFi card that comes in the x220 work? If not what are some WiFi card that are compatible with the x220 (mac and windows)?

Second, My trackpad doesn't seem to recognize physical clicking of it. It only recognizes taps on the trackpad. Are there any fixes to this?

Lastly: Is EasyBCD the best option the duel boot Mac and Windows, are there any other options (EasyBCD seems a bit buggy to me).

Intel wifi card are not supported on OSX. and if you use the standard wifi card change the bios is useless. ( you put a modified bios when you put a different wifi card than the original)

^So, what are some WiFi card that are compatible with the x220 (and mac and windows)?

I don't know exactly what they do, but they are Chameleon modules.

First, let me thank for such a great tutorial! Bravo! I followed this guide and got almost everything working perfectly - except for WiFi.

I am running 10.7.3. I have X220 i7 with intel WiMax card and bluetooth.

I reflashed 1.28 whitelisted bios and replaced intel wifi module with dell dw-1515, but no wifi icon in the finder. I even tried installing HP aetheros equivalent which worked fine under win7, but again no go under OSX.

Without WiFi module I still get working bluetooth, but it would be nice to figure what's going on. I can see dell dw-1515 as a pci device.

Any ideas?

Generic SSDTs for i5 and i7 processors are out. Check out the following link.
https://tonymacx86.com/viewtopic.php?f=169&t=60811

dw-1515 should work with native driver on OSX. However, it is true that 10.7.3 sometimes fails recognize AR9280 (dw1515).
The fix is to remove

from /System/Library/Extensions/IO80211Family.kext/Contents/PlugIns/AirPortAtheros40.kext/Contents/Info.plist, and reinstall IO80211Family.kext

There are other possibilities as well. Knowing the device ID of your dw-1515 card and related boot log (*Atheros*.kext) will be helpful.

Can you maybe try to explain the sound fix, how and where to install the Kexts for the updated new sound fix?

Just download the zip file from here, and extract to get the patched AppleHDA.kext.
Then replace the stock AppleHDA.kext with the patched one.
