[Guide] Success! Install 10.8 on old unsupported Mac

[IllmasterMath]

i basically added your board ID to OSInstall.mpkg. Report back when installations completed.

----------

Okay, now have to work on X1900 and X1600.. Any ideas where i get 64bit version of the kext?

Installation completed successfully. Working on 8-12, will update this post when I try to boot.

Update: There were a few hiccups installing the kexts like the computer not wanting to restart. Graphics work as intended but sound does not. Most or all system sounds seem to be working but that's it; nothing from files or Safari.

Updated Update: Sound works. I don't know why because I didn't do anything.

i basically added your board ID to OSInstall.mpkg. Report back when installations completed.

How to do that? I need it too but I can do it from myself if you simply explain to me how to modify the mpkg ^^

Why not just download the hacked mpkg? it now includes all the board IDs except the core duo Mac Minis

1. create a new folder on your desktop
2. make a copy of OSInstall.mpkg and drag it to your new folder
3. Open Terminal and type (except the $)

$cd desktop
$xar -x -f OSInstall.mpkg

4. You should get 2 file "Distribution" and "Resources"
5. Right click on "Distribution" and Open With > Other > Text Edit
6. Depending on what you want to modify, this guide covers 2 modification

* Lower RAM requirement(s) (default ML requires 2GB ram, ill lower it to 1GB)
- Find "var minRam = 2048" and change it to "var minRam = 1024"
- Find "var requiredRAM = (RAM * 1024 * 1024)" and change it to "var requiredRAM = (RAM * 512 * 512)"

*Adding Board IDs
- Find "var platformSupportValues" and add your Board ID in.

7. Delete the OSInstall.mpkg from the new folder, so now the folder only has Distribution and Resources

8. In terminal type

$xar -c -f OSInstall.mpkg *

9. you should now see a new OSInstall.mpkg in that folder.

Great news! I also have a MacBook 4,1 and, like you, had carefully followed the instructions (I also was confused by the duplicate .plist) only to have it boot but not install. I just gave up and saved the log (here if you're interested).

Not enough time to test that new package now unfortunately, but something to look forward to tomorrow!

Probably worth updating #22's main link with that package so 4,1 owners don't end up all confused

Thanks Illmaster + hackerwayne.

Same issue, try the new package, it should solve your issue.

Up to date directions

Hey,
Could someone post complete up to date directions for the procedure on the X3100 for MacBook 4,1 or anything else? This 20 page post is hard to follow and I'm sure everyone who clicks this would like to know the current status. Thanks!

Thank you very much! I haven't noticed you had included all the boards

On my macbook 4.1 with 4GB and x3100 i boot with the thumb but before the spinning wheel it appears a white screen with just the cursor.
I can't save the log btw!

..please tell me what's the exactly log file

Follow the conversation between hackerwayne and myself starting on page 18. Using a modified OSInstall.mpkg I was able to get Mountain Lion running on a MacBook 4,1. It goes in System>Installation>Packages on the flash drive you created.

Besides that, I followed the guide on the first page.

And by using this modified install file, following everything starting on page 18, and the thumbdrive technique, all with post #22, It functions? Ok. Ill try and compile what I read and post the results for critique. Thanks.

 

[EnricoBaradJ]

Yeah i know i've done that.. I recreated the thumb with the last updated guide (post 22) but it appears a white screen...

I think so. Following the guide on the first page, only one additional step is required. After completing step 7, download the modified OSInstall.mpkg file in the quote below and use it to replace the one in System>Installation>Packages on your flash drive.

There you go. New patch, if it works, that means i missed something in the guide. HackedOSInstall.mpkg

Aight

Alright Bro, So now I follow.
I won't be able to try any of this till morning as I don't have a large enough thumb drive, and ML hasn't finished downloading. No chance of this working off an external hard drive instead?

Any news on FaceTime, Messages, etc? I read that they were having issues in previous posts.

As a matter of fact I installed on an external hard drive, so I don't see why it wouldn't work the other way around. I'm in the process of using Carbon Copy Cloner to move the installation to my internal hard drive, but when it finishes I'll sign into iCloud and stuff and let you know.

iMessage and FaceTime both work, though FaceTime makes the fans kick in pretty heavy.

That has been added into the guide @ #22

 

[MCLBama]

Thanks guys I appreciate it. Illmastermath, thanks for checking into iCloud, iMessage, FaceTime, etc. I'll look for your reply in the morning, and let you know how everything goes, but I might be a day or so before we know anything with my current schedule.

__________________________
Just saw your post about iMessage and FT. I dont use FT that often, so... Thanks a bunch.

 

[foldericon]

Don't add the kexts and try again.

Ok, i did everything from beginning and got it working now. i just forgot the hacked OSInstall.mpkg
I think i can life without the graphics things, even without sleep-mode,
but the display brightness thing is just annoying. Is there any way to switch off the internal display completely and let the external attached one still intact?
I tried some techniques from lion to do that (command line via nvram, lid close, changing brightness in display prefs) but none of them worked

Thank you for all your hard work to get this up!

Last Minute Question

How well is iTunes working with iOS devices on this? This one is kind of critical for me, as I am all Apple, all day long.

 

[Mautz001]

iTunes works OK Nobody else has iMessage / FaceTime Problems?

 

[Archy]

Installer starts on MB 2006 later 950,
but "your computer is not compatible..."

 

[BakaAlex]

¡Hopefully fix the brightness, Facetime, Imessage and QE/CI in Gma 950 Macbook!

What card do you have? GMA 950 or X3100?

 

[justin02]

Thanks for the guide, it works great on white macbook late 2006 gma950

In noticed the screensavers dont work either, I assume this is the driver issue for the 950?

Also is anyone getting the error from icloud in the settings:
This Apple ID is valid but is not an iCloud account ?

Trouble booting up installation

Hello everyone,

first of all, thank you for your efforts and the great guide!

Unfortunately I have some trouble following the instructions on #22 for my Macbook 3,1. I use the retail version of ML as source. I am able to boot up the thumb drive with holding down option key at the beginning. It starts booting, apple logo appears,

continues with adding the spinner to the apple logo.

But after a short while (approx 30s) the apple logo get switched to the circle with the line, nevertheless the spinner remains.

Unfortunately the Mac does not do anything else as sitting with this screen for ever. I did some pictures for documentation. Do you have any idea what goes wrong?

Thank you for any help!!

iCloud fix: Restore your settings via "Migration Assistant" that works but not for iMessage, FaceTime, Game Center and so on -.-
