OS X 10.8 for old Macs (Graphics Working!)

Hi !

Sorry if my English is bad, I'm French.

I recently succeeded to install Mountain Lion 10.8.2 on my Late 2006 iMac with ATIRadeon X1600 graphics who is worked very well (with graphics acceleration and OpenGL Support) !

Macs who work with v2 :

iMac X1600 : Perfect
iMac GMA 950 : Perfect
MacBook GMA 950 : Perfect
MacBook GMA X3100 : Perfect
Mac Mini GMA 950 : Not tested, should work !
MacBook Pro X1600 : Not tested, should work !

Macs who work with v3 :

iMac X1600 : Perfect
iMac GMA 950 : Doesn't work yet
MacBook GMA 950 : Doesn't work yet
MacBook GMA X3100 : Doesn't work yet
Mac Mini GMA 950 : Doesn't work yet
MacBook Pro X1600 : Not tested, should work !

---------------------------------------------------------------

Hack ML v3 : A Totally new Hack for ML !



Change log :

- Add 64 bits support
- Add 64 bits Graphics support with sleep and QE/CI
- Fix Networking problems
- Fix kexts problems
- Fix iSight problem (lags).

Public Testing !!!!! : download the beta here !!!

SAME GUIDE !

State :

- This works perfectly on my iMac Late 2006 ! Should work on MacBook Pro who have ATI Radeon X1600 Graphics !
- This doesn't works on any MacBooks yet because there isn't 64 bits driver for GMA Graphics... (PM me if you are skilled in decompiling, in c.....)
- It takes more time to boot than v2.
- You can't choose your startup disk from ML (System or Installation).


Can I add my graphics card to the Hack ?

- To add your Graphics Card, the kexts must be 64 bits and from Lion 10.7.5.
- PM me if your Graphics Card (except ATI Radeon X1600) works.



---------------------------------------------------------------

Here the method I created (Text) :

1. Buy ML via the MacAppStore
2. Go to your Install Mountain Lion Application -> click Show Packages Contents -> Contents -> SharedSupport -> and mount InstallESD.
3. open a terminal and type : open /Volumes/Mac\ OS\ X\ Install\ ESD/basesystem.dmg
4. Partition your Hard drive (see pics)
5. Restore your Installer partition with Mac OS X Base System
6. When restoring operation is finished, eject Mac OS X Base System DISK IMAGE and rename your Installer partition to ML Setup (with a space between ML and Setup).
7. on terminal, type : sudo rm /Volumes/ML\ Setup/System/Installation/Packages
sudo cp -R /Volumes/Mac\ OS\ X\ Install\ ESD/Packages /Volumes/ML\ Setup/System/Installation
8. When copying operation is finished, download this file here (Hack ML v2, don't download if you want to test v3 !).
9. Unzip this and move the folder on your startup disk (/).
10. Go to the Hack ML folder, and open Install.command
11. After running, you should be see the message : Done ! You can....
12. Boot into your ML Setup partition and Install ML on a partition who must be named : ML
(If it's doesn't boot (Waiting for DSMOS), boot into your main system and type on a terminal window :
sudo chmod -R 755 /Volumes/ML\ Setup/System/Library/Extensions
sudo chown -R root:wheel /Volumes/ML\ Setup/System/Library/Extensions
13. After installing, you should see Installation Failed. It's not important, It's normal !
14. When you see this error message, go to Utilities -> Terminal and type : /Hack.command
15. After hacking, close terminal and reboot into your ML disk (It named ML).
16. enjoy with ML on your iMac or MacBook !

The method in images :


































The "rm : No such file or directory" error is removed with Hack ML v2.


Continue to follow steps 11, 12...

PS : To Upgarde to 10.8.2, apply the update via the Mac App Store. After installing, reboot into your Installation and reapply /Hack.command on a terminal. Then, reboot into your ML disk.

MLforAll on twitter, please follow, I publish news (In French, sorry) for the Hack's state.

I haven't Lion or SL partition because I use ML on my main partition but I will update the guide with screenshots adding.

This is a pic from my iTouch 5G :



You can see a Early 2006 iMac Core Duo upgraded to a Core 2 Duo and running Mountain Lion's Launchpad (search bar) !

The dock issue is only for GMA950.
But, it's a fix for that :

Open a terminal window, from ML and type :

defaults write com.apple.dock hide-mirror -bool yes
killall Dock

You should see the dock background after typing that.

For the keyboard, I work on that. It's a issue with their keyboards.

RSL, the MacBook 2,1 has better graphics performance than Lion !
The Launchpad isn't lacked like Mission Control, switching desktops, the Notification Center... All have better graphics in Mountain Lion !

I'm very happy to have it as my Main System !

Specs :
OS : OS X 10.8.2
Graphics : GMA 950, 64 MB
RAM : 3 GB
Model : MacBook 2,1

PS : Sorry for my server problems, it's an electric problem

Michelasso,

- The GMA 950 kext are from Lion 10.7.5 !! I create a combined OpenGL.framework for their support on Mountain Lion !!!!!

- The sleep worked, like brightness !!! The graphics card is FULLY SUPPORTED !!!!!

- You can download the file here !

------------------------------------

MacBook 2,1 Graphics Performance on ML here.

You need to copy these file from Lion 10.7.5 to ML :

- AppleIntelGMAX3100.kext
- AppleIntelGMAX3100FB.kext
- AppleIntelGMAX3100GA.plugin
- AppleIntelGMAX3100GLDriver.bundle
- AppleIntelGMAX3100VADriver.bundle

Your graphics should work after repairing permissions :

- with Kext Utility or
- with Disk Utility or
- with terminal :
sudo chmod -R 755 /System/Library/Extensions
sudo chown -R root:wheel /System/Library/Extensions

The patch do :

- replacing Extensions folder with the dp1 Extensions folder
- replacing mach_kernel with the dp1 mach_kernel
- replacing OpenGL.framework with my modified OpenGL.framework
- adding GMA 950, ATI Radeon X1600 kexts on ML.

To apply the patch :

- You need to create ML Setup disk (Installation disk)
- Patch it with the file who can be downloaded (It must be placed in the root of your startup disk).
- Boot into ML Setup.
- Type in terminal (Utilities -> Terminal) : /Hack.command

The patch work on 10.8 and 10.8.2 ML Systems !

My tests :
I tested the patch on 10.8.0 then I update my system to 10.8.2, reapplying the patch and it rebooted fine on my ML 10.8.2 fully working !

mishendr,

- Your Installation disk must be named "ML Setup" (without quotes)
- If it doesn't work anymore, type : rm /Volumes/ML\ Setup/System/Installation/Packages
before.

mishendr,

I'ts normal, you can reboot and install ML !
