Thank you. Is it even possible? As noted elsewhere within EveryMac. Some users may view this increasingly short support timeline unimportant, as they wish to purchase a new computer or a newer computer every couple of years and have little need for "legacy" software or document support.
Others may be quite happy with the computer they have -- even if it is a few years old -- and are not interested in upgrading to Mountain Lion, regardless. However, for those who would like to run the latest operating system and have a Mac officially capable of running Lion, but not Mountain Lion, there are obstacles to overcome.
Installing Mountain Lion on an unsupported Mac involves defeating these issues. Where there is a challenge, it is a safe bet that hardworking hackers will rise to the occasion. Do not attempt to install Mountain Lion on an unsupported Mac if it is "mission critical" or data is important. Any hacks are performed at your own risk. Be absolutely sure to backup everything before proceeding with any experimental hacks or before proceeding with any official operating system upgrades, for that matter.
Although the process of installing Mountain Lion on these Macs is complex, and involves a hardware upgrade of the graphics card, a second hard drive, and an assortment of " Hackintosh " tactics, the diligent hacker " Jabbawok " prepared a straightforward tutorial archive copy, original no longer online. The equally diligent hacker "hackerwayne" has provided a detailed tutorial to install Mountain Lion on other unsupported Macs, including custom kexts drivers from hackers "kylegray" and "trunkz" for partial support of GMA and X graphics.

Notes As you can see, all of this editing is being done to the installer, not to your system Many forums have long winded workarounds and have you editing your system; however, these methods are extremely inefficient and are unnecessarily complex.

Step 7: Move all items modified from the OS X installer back to their original locations. Step Wrap-Up When the installer finishes, replace the 3. Afterthoughts For all intents and purposes, your upgrade is complete, although there are other things to keep in mind: The bit EFI loader is not optimized to work with graphics cards smaller than MB.
The catch here is that if you run a larger PC card, you will not see the verbose screen upon start up. To change this natively and have the machine recognize the chips rather than fooling it by editing plists, you must find the Mac Pro 2,1 firmware update for the Mac Pro 1,1; Apple used to offer it, but has since taken it down perhaps buried in the archives somewhere.
To my knowledge, these steps will work on any Mac out there as long as you know your Board ID. This should also work fine with Yosemite in all scenarios. The best part is that once you have the upgrade applied with the modified boot efi, you can then begin upgrading natively from the app store and just replace the boot.
