OS X Yosemite on unsupported MacBook

[amitkottur]

I was able to install Yosemite on my MacBook4,1 by creating USB bootable version of Yosemite. Changes required were the usual OSXInstall.mpkg replacement and update to .plist files.

However, after installation I am unable to boot into Yosemite . Any thoughts on how to get it working?

maybe you have to modify the plist adding your motherboard to compatibles ones

During the Installation. It adds a new platformsupport.plist that does not have your Mac identified as supportive.

Try opening up the OS X Install Usb and find the Terminal. Enter this:
sudo rm /Volumes/<10.10 Partition>/System/Library/CoreServices/PlatformSupport.plist

Make sure you have 64bit kexts from OS X (10.6.2) Snow Leopard to help avoid the harsh graphical artifacts.
Unsigned or improperly signed kexts will not be loaded easily. To use unsigned kexts during development, this strict check can be disabled by adding a “kext-dev-mode=1” boot arg.
Installing kernel extensions on systems running the Public Beta and Developer's Preview may make your system un-bootable. To fix the issue, boot into the Recovery Partition and run the following:
touch /Volumes/<10.10 Partition>/System/Library/Extensions
kextcache -u /Volumes/<10.10 Partition>

We are working on making automated Yosemite Patches and Recovery Partition Creation on these unsupportive macs as well.

Here is my Guide for Mavericks. Yosemite may have a signed OSInstall.mpkg but you should be able to get past that easily:

You may use those kexts in your provided link or pm me for working ones.

what do you mean for "working ones"?

The old Intel and nvidia graphics that came on these macs don't have kexts in anything past lion, and after that there's no support for 32-bit kexts. The only 64 bit kexts for them are the one from 10.6.2.

I had the same problem.
So using SFOTT I successfully installed Os X 10.10 Yosemite Beta on my MacBook 4,1 with the help of this, but was unable to boot into Yosemite partition.

My problem was solved:
After installation sfott on your USB-stick try to replace boot.efi BOTH in /System/Library/CoreServices/boot.efi AND /usr/standalone/i386/boot.efi
It works on my own.

How do I update my mac to 10.10.3, I have a macbook 3,1 and managed to install yosemite using sfott and changing the plist, I want to update to 10.10.3 I tried with software update and I had a prohibitory sign. Was wondering how I go about updating and having working intel x3100 kexts.
Thanks

I had to use a friend's machine (French laptop) with AdBlocker Plus in Firefox (seperately)... Disable it, then there's a menu under that with an arrow to the with two options... one is Java and Firfox, then another. untick both and reopen MacPF.

Im English and was using a French language laptop, so sorry if vague, but that got me past those steps...

I believe it's since been fixed...
