[Guide] Success! Install 10.8 on old unsupported Mac

Yep, that's what I meant to say - by "since" I meant they dumped 32 after the first or second beta. Sorry I didn't word that better.
Personally I would avoid trying to use DP1 as a way to run 32 bit drivers.
Hi,
looking through the thread, I noticed that there are plenty of people who make one mistake or another trying to get things bootable. Therefore, I decided to write an installer that prepares the ML installation properly. It works nicely on my MB with GMA950.
Due to local legislation, however, I can only upload an incomplete program. If your legislation permits, you can complete the installer and reupload. To show you what you need, I am also uploading an SHA1SUM file. In essence, you just need to put the zip files required for installation (MountainLionHack.zip, hackedOSInstall.mpkg) into MLInstaller.app/Contents/Resources/root-ESD using the correct path hierarchy.
The Kexts.zip required for the final system go into MLInstaller.app/Contents/Resources/root-Install .
If you did everything right, you should be able to validate against the SHA1SUM file.
Hoping that it's useful to some of you...

EDIT: As you have probably already guessed, this implements what hackerwayne describes in post #22, so credits go out to him as well as Sveto and all the others I forgot for their research.

filled up the app according your explanation, and whats next? double click the app - nothing happens.... what is expected to happen?
Question. What part of an app tells it which OS it is compatable with? I opened up the Applications folder with OS 10.7 Lion, and of course, the Notes app has the no smoking sign over it, and it says it's not compatable with Lion, which makes sense. But I figure all it needs is to either think it is compatable with Lion, or think it's running Mountain Lion, and that we might be able to spoof that with editing a bit of its code. I don't think it's that hard. I'll look into it, myself, but my knowledge of OS X code is limited so I don't know exactly where to look.
So why am I posting this here?
I honestly think that the future of this thread should trend toward trying to migrate the features of our legally owned copies of 10.8 to Lion. Some clever coding could do this easily. But legally, you have to do it from your legally owned copy. If this suggestion is against macrumors policy, feel free to edit it or delete it. But this would overcome out no QE/CI issues, and everything else, because Lion works, and putting the apps in would be Awesome. Cause they'd work.

It might not be as simple as you think. Some of those apps probably use frameworks not present in Lion. Especially anything having to do with iCloud syncing which is much improved in ML.
How to hack app to run on lion
Hacked Notes and it quit on launching though the "no smoking sign" wasn't over it after hack.
How i hacked:
Control+click on app.
click on show package contents
open contents
open info.plist
Find this:
And change 10.8 to what ever version of lion you are using (i am apple dev so using 10.7.5)
Have fun!!!

I need help for installing ML on a middle 2008 imac, (Model Code: a1145), i followed the step by step guide on the topic #22 but when i insert the thumb drive in the iMac and start from it, the installation of mountain lion dosen't appear and after some minutes when i give the apple logo with a rounding circle below, on the screen appear the stop cross signal and the imac after few second turn off.
where i go wrong? i followed the guide step by step!
Please Help Me!!! =(

PowerBook uses the PowerPC architecture and would require a Complete bottom to top rebuild of the OS just to run Snow Leopard. Used MacBook Pros that are ML capable are going for $450. Sorry, friend. We know your pain. I only got my MacBook used about 4 months ago and I had to hack 10.8 on it so I know where your coming from. But a PPC port just isn't going to happen.
Make sure you replaced the kernel in all the places and also the bootablemechines.plist.

Yes... now it's works fine!! i've installed all the Kext from the guide.. but when i try to open the launchpad the system freeze and i only restart them by pressing and holding the power button!! Every time do this!! same thing for all the graphics... all glitch... in my imac i have the intel 950... but i have installed correctly the kext! Why i have all this problem?! it's seem that the kext Won't load at startup...
It does that for everybody, you just need to let it sit for a while after opening launchpad.
Let it sit for a while... It stay stucked forever...It does that for everybody, you just need to let it sit for a while after opening launchpad.
I don't believe this... Following the guide at post #22 I manage to successfully install ML in my MacBook 2,1 using the GMA 950 kexts without QE/CI support, and...
THE HTML5 VIDEOS PLAY MUCH BETTER THAN IN LION?!??!?!?!
No stutter at all!! I have been getting crazy for 2 years!
The only issues I've had until now is Launchpad blocking temporarily the system and the Safari Top Sites page getting pretty slow. Otherwise it is speedy!
Apple, I hate you. There were no reasons for not supporting all 64 bits Macs!!

YouTube Workaround:
Right click the black video, go to Settings and disable Hardware Acceleration.
That should do it for Flash.
I'm not sure if this option has already been looked into: Can't we just use the DP1 kernel in GM to load the 32bit Kexts?

Ok, I did some more testing on my MacBook2,1 with GMA950. This is what it is broken (just confirming what other people experienced I suppose):
- sleep/wake: I had to press power to reboot. No sign of life
- iCloud: complaining the ID Apple is valid but the device is not. Probably because I miss the restore partition
- Screen thumbnail in Mission Control are messed up
- Launchpad works but the first time is S L O W. Later it gets a bit faster. Still too unresponsive
- Safari Top Pages are slow. Omnibar may get slow typing
- MX Player not showing the video. Just the sound.
All together is not worth to be upgraded. It is better to stick with Lion.The only hope is that a device driver developer will make working GMA 950 64 bits kexts with QE/CI. And even then I am not sure it will be perfect.

That's what I'm waiting. But, that says What-Ever, may be just using kernel DP1 in our ML it can load 32 bit drivers.
This seems two ways, and I don't know which of two both ways are harder.
So you'd rather use the first beta release of the kernel, not even supported by Apple, with32 bits kexts that still had trouble running? At least I couldn't make DP1 recognizing the GMA 950 with Lion kexts.
That's not a solution. The only possible second way is to try recompiling the kernel from the open source code. And even there hoping that there still is the 32 bits code. Apple may have decided to strip it once for all (at source code level, not just a Universal binaries level). And hoping the kexts will work.
Nah, we need the GMA 950 64 bits kexts. Someone in the world must be able to make them. Hopefully.
Excellent guide thank you. Have Mountain Lion working perfectly on a 2008 XServe2,1. The only major issue i had was the ATI X1300 graphics card on it. Even without the drivers, the machine performed fine with obvious exceptions like slow Launchpad, but Remote Desktop was beyond sluggish. Copied across the X1300 drivers from Lion, and all is fine 
Though i did have to remove the AMDSupport.kext from Mountain Lion as it was conflicting with the Lion ATISupport.kext that i'd put in. If anyone has any difficulties when copying drivers across, do look at Console.app, it often tells you what's causing driver problems.
Remote Desktop is still a bit slow, but useable. If that's all i have to put up with to make Mountain Lion Server work and keep a £3000 server running for another 2 years, then i'm happy!
