Question :
I read somewhere that it is possible to install the latest version of OSX 10.10 Yosemite on my Mac, even though the official installer refuses to install.

After you install Snow Leopard you will have to download and install the Mac OS X 10.6.8 Update Combo v1.1 to update Snow Leopard to 10.6.8 and give you access to the App Store. Access to the App Store enables you to download Mavericks if your computer meets the requirements. Snow Leopard General Requirements. Mac computer with an Intel. Make sure you have Install OS X Mavericks.app in your Application Folder 2. Select 'On an external drive' on the main MCPF window. Then, choose the disk you want to install the Mavericks installer on. Click install and prompt your password. Boot the computer you want to install Mavericks on with 'alt' held and select your USB drive.
Can you give me any directions ?
Answer :
Installing newer versions of OSX on slightly older Macs that do not meet the official system requirements can be done using MacPostFactor (MCPF).
MacPostFactor also supports installing OSX versions up to OSX 10.10 Yosemite on older Macs. And a new version that supports installing OSX 10.11 El_Capitan is in the works.

There are known vulnerabilities for Mac OS X 10.9 'Mavericks' that are not addressed by Apple. Users should migrate as soon as possible to a fully supported version of OS X, see https://information-technology.web.cern.ch/services/fe/howto/software-updates-mac.
The information below is only for historical reference.
My suspicion is that the new installer will use it’s own boot.efi / PlatformSupport.plist file(s) preventing you to upgrade using the App Store. My reasoning is that I tried to download the Mavericks Install file from the App Store on the Mac Pro and the App Store prevented the download from happening since the Mac Pro is unsupported. My best advice for any Hackintosh install, is get things installed on a real mac first, and then modify things to work on your unsupported rig. This worked for both the Xserve and my i7 PC. I had a junky MacBook Pro sitting around I did the Mavericks install with, and then modded the PlatformSupport.plist. Install 10.8 on old unsupported Mac. It is a very long thread. I still don't definitively know if you can get the OS X 10.7 64-bit kernel running on your specific kind of Mac, but I suspect for the reasons mentioned in this image from the MacRumors forum thread that you can't.

Mac Os On Unsupported Mac
- 'Thirty two sixty four for Mac OS X' search that in Google, you can run Mavericks and Yosemite on any unsupported mac with at least a core duo processor, just down load the software and follow the directions. And FYI you can install windows 10 on any Intel mac.
- The 1.6.5 installer for Mountain Lion refuses to install on Mavericks, so if you want to use it on Mavericks you must install it before you migrate or hack the install package to disable the OS version check. ROOT v5-34-12 builds and runs fine on Mavericks. Previous versions don't and won't.
Mac OS X 10.9 Mavericks is available since October 22nd 2013. It can be installed directly from the Apple AppStore, or via our NetInstall server (see https://information-technology.web.cern.ch/services/fe/howto/install-os… for details anbout our NetInstall service).
There are three important actions to take before you install Mavericks:
- Ensure that all the software you are using is compatible with it.
- Verify your hard-disk or SSD before doing the install.
- Make sure you have a recent backup, allowing you to recover your data in case of problems

Openafs
OS X 10.9 requires openAFS version 1.6.6, released on January 24th 2014, or higher. The version 1.6.5 for Mountain Lion appears to work for most cases, but there is a problem when editing files in afs directly from emacs or when creating symlinks within the afs space.
