Installare Mountain Lion su Macchine non supportate (OLD)

[Scialla]

Posto una piccola guida reperita su internet gongolando, credo che, appena avrò un attimo di tempo, avendo un MacBook bianco late 2006 con Intel GMA950, giusto per smanettare un po', proverò a seguire la guida

UPDATE: 7/26/2012 The guide has been modified to fix "Mac OS X can't be installed on this computer" problem & support the retail version of Mountain Lion.

A little note:
Unfortunately, either Apple has completely removed 32bit kernel, or locked it up. I tried to start it by holding down "3" and "2" and by typing arch=i386 in com.apple.boot.plist did nothing. (Kernel is still LP64) And because of that, I can't get 32bit kexts started such as ATI1600Controller.kext and all the Intel GMA950 kexts.


What works what doesn't (to avoid confusion)
- Mac Minis with X3100 > Perfect
- Mac Pros with upgraded graphics > Perfect
- MacBooks with X3100 > Works, display brightness & sleep issue
- MacBookAir with X3100 > Works, display brightness & sleep issue
- MacBookPros with X1600 > Graphics Issue (Frame buffer mode with Core Image lacks Quartz Extreme)
- iMacs with X1900 > Graphics Issue (Frame buffer mode with Core Image lacks Quartz Extreme)
- MacBooks with GMA 950 > Works, no QE/CI
- iMacs with GMA 950 >Works, no QE/CI
- Mac Minis with GMA 950 > Works, no QE/CI
- Mac Pros with 7300GT and X1900XT >Doesn't work at all, no plans to fix it
- iMacs with 7600GT > Didn't work on it yet, don't have such a system to test on.


For education purpose only. Try at your own risk, please back up everything before installing or install it on a second partition.

Requirements:
- a Mac with Core 2 Duo processor and with Lion installed.
- At least 2GB of RAM.
- A copy of Mountain Lion.
- 8GB USB Thumb drive
- A second partition with at least 20GB free. Name it Mountain Lion.

Full instructions:

1. Get a copy of Mountain Lion, please purchase the retail version of ML from the Mac App Store. Seriously, buy it, its only $19.99

2. Boot up to the Lion partition, show hidden file in Finder. Google it if you're unsure.

3. Right click on OS X Mountain Lion.app and click "show all content" Navigate to Shared Support and drag "InstallESD.dmg" to your desktop.

4. Enable hidden files if you haven't. You should see a file called BaseSystem.dmg, open it and mount it.

5. Plug in your 8GB thumb drive and bring up Disk Utility. Click on the 8GB drive and select "Restore" tab, next, drag BaseSystem.dmg from the sidebar to "Source" and the thumb drive to "Destination". The process should take approximately 10 to 20 minutes, when its done, go to the newly restored 8GB drive, navigate to System>Installation and replace the file "Packages" with the one in InstallESD. The file should be 4.xGB.

6. Once the copying is done we have to replace some files, download this modified 1.14MB zip file. and this hackedOSInstall.mpkg

7. Open up both ZIP files. You should get a folder called MountainLionHack, and it contains 2 folder, which is CoreServices and i386, and a file called OSInstall.mpkg Open up the 8GB thumb drive, navigate to /System/Library and MERGE the patched CoreServices folder in, when it ask about files replacement, click replace. Next, on the same 8GB drive, navigate to /usr/standalone and MERGE the patched i386 folder in. Replace files when asked. Then, go to /System/Installation/Packages and replace OSInstall.mpkg with the newly downloaded one.

8. Reboot your Mac and hold down "Option" while booting. Select the thumb drive and hit enter. Once you're at the installation screen, click next till you reach the destination drive, click show all drives and select the 20GB partition you made for Mountain Lion, hit next to install. Once installation is completed system will restart, DO NOT try to boot into Mountain Lion. While restarting, hold down "Option" and boot back into Lion 10.7. Bring up Finder, open Mountain Lion drive and navigate to /System/Library/CoreServices and replace PlatformSupport.plist with the one in MountainLionHack folder.

9. Reboot into Mountain Lion drive and set up your Mac. (Guide is not done yet, please continue reading)

10. You will realize that sound and graphics will not work.
Note: Fix sound guide will be up in a bit.

UPDATE: 8.55PM GMT+8
Sound guide
- First download this zip file, it contains 2 file, 1 hacked AppleHDA kext by me, and Kext Utility by Cvad-Mac.
- You will need to install the hacked kext. Launch Kext Utility and drag AppleHDA.kext into Kext Utility. Type in your password and wait. Once its done, reboot and you should get sound now.

UPDATE: July 13th 2012
iCloud and iMessage fix (yeah iMessage sort of, not tested by myself. Report back if it works)

After the installation, use Migration Assistant to migrate iCloud settings from Lion.
11. Working Mountain Lion on not supported system. (Except graphics, for now)

- Use the same Kext Utility download the ZIP from the sound fix, and download X3100Hack and install following files in Mountain Lion:
(all are located in System/Library/Extensions in your Lion installation you install them to Mountain Lion in the corresponding place)

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

Lo farò anch'io sul MacBook !! Grazie per la segnalazione!!

Il primo che lo fa, racconta poi come è andata

Ma una guida per montare Leopard sui futuri Mac, non c'è?

[Scialla]

E' ora...
Clonato SSD con CCC
Fatto backup con TM

Io ci provo

A dopo

Niente, non fa il boot;
Voi cosa capite in questa frase?

Now, navigate to ‘/System/Library/CoreServices’ on the Mountain Lion partition. Unlike 10.7 Lion, users delete PlatformSupport.plist. In ML 10.8 add that unique ID that you copied just now to PlatformSupport.plist. If you try to delete that Plist file, a Kernal panic will greet you during boot.

In PlatformSupport.plist, remember to add your model identifier, if you are using a MacBook White like me, add MacBook2,1 right above MacBook6,1. This step is important as the EFI reads this by sequence.

Io capisco che devo editare il file PlatformSupport.plist ed aggiungere l'ID del mio MacBook bianco che rilevo in fase di boot in modalità verbose
Mi sono segnato l'ID
L'ho aggiunto al fondo delle SupportedBoardsIds (ne erano 54 ora diventate 55)
Ho aggiunto MacBook2,1 nelle SupportedModelProperties, proprio sopra la voce MacBook 6,1 così come indicato che si è posizionato quindi al nr. 38 di 40 object (prima erano 39)

Rifaccio il boot e non cambia una cippa, continua a non bootare e dare l'errore dal quale si rileva l'ID se vado in verboso

Dove sbaglio?

[Scialla]

Ho provato anche a prendere il PlatformSupport.plist da Lion e a sostituirlo, come suggerito da gente che è riuscita, ma il risultato non cambia...

[Scialla]

Che bello, quanta gente che partecipa!
Boh, per ora mi arrendo e ri-clono tutto...
Ho provato anche a cancellarlo proprio quel maledetto file ma non cambia nulla; ho provato a bootare dall'iMac senza il file e parte!!!! Incredibile...

Il problema deve quindi stare a monte di quel file, ovvero nell'EFI, e mi domando quindi come abbiamo potuto fare quelli che ci sono riusciti, boh

La prossima volta ritento con la prima guida, quella un po più gabolosa...

Prossimamente... su questo Topic

[mauropasha]

Mi dispiace, ma non riesco proprio a capire cosa stai facendo…
Però ti posso dire che anch'io ho capito quello che dici tu.
Avevo avuto un dubbio con quell'above, perché tu scrivi

...L'ho aggiunto al fondo delle SupportedBoardsIds...

ma poi specifichi

...Ho aggiunto MacBook2,1 nelle SupportedModelProperties, proprio sopra la voce MacBook 6,1 così come indicato...

per cui… mi sembra tutto giusto.
Buona fortuna

Tutta la mia solidarietà ed empatia ma sto già sbattendo i denti con l'affaire della scansione delle dia. Auguri. E anche a te.

Qualcuno ha per caso scaricato la versione 0.3 di MLPostFactor?
Non riesco a trovarlo da nessuna parte

[Phate]

A quanto pare non è ancora uscita la versione 0.3
