What's new in SFOTT 1.4.4:

Jul 25, 2012 Other unsupported Macs like iMacs, Mac Minis, and MacBook systems have graphics cards that cannot be upgraded; therefore even if the emulated firmware is installed, on these systems Mountain Lion. Now, by using disk utility 'restore' feature, clone 'InstallESDHacked.DMG' into a flash drive, and use it to install mountain lion on the unsupported Mac. If you did everything right, after installation you should be able to reach the desktop, but have no accelerated graphics whatsoever, only framebuffer.
- Many older Macs lost out on the ability to run OS X Mountain Lion (10.8.3!), but some hard working fellows have created a free third party tool called MLPostFactor that allows for the newest version of OS X to be installed on older, officially unsupported Macs. The process used to be quite complicated, but with MLPostFactor it’s easier than.

Mac OS X Mountain Lion, Mavericks, or Yosemite can be installed only on certain Apple computers that come with 64-bit support which means, that if you have an older, 32-bit model you cannot run the latest OS.
SFOTT is an AppleScript utility designed to help you prepare a USB disk or media storage device for installing Mountain Lion, Mavericks, or Yosemite on unsupported 32-bit Macs.
The script is based on a boot.efi developed by Tiamo at MacRumors, and its goal is to automate the key creation.
Make sure your Mac can support the respective OS
Before you get started, verify that you have installed the SFOTT app on the target Mac, that you have downloaded the Yosemite installer, and that you have a USB drive connected to your computer (a 8GB USB should be enough).
In some cases, some upgrades, such as changing the graphics card, or adding more RAM, can make your Mac compatible with the Yosemite OS X, even if it's not officially supported.
Note that you must decide on your own if this is the case, and that the unsupported OS installation might lead to data loss or to breaking your Mac.
Adjust the SFOTT settings via the Terminal and generate keys for the target computer
Once installed, the SFOTT script can be launched from the Utilities folder included in the Applications directory.
In a Terminal window you can see details about the current computer, about the current configuration settings, and if you have a 32-bit or 64-bit firmware. Even though you can change the configuration settings, it is advisable to run the SFOTT app on the target computer.
Install Lion On Unsupported Macbook
SFOTT offers you the possibility to generate new URB or media keys for the Yosemite installation step by step or in autorun mode.
To make sure everything works properly, check out the online SFOTT documentation made available by the developer, or the Read Me file included in the archive.
Install the latest OS X releases on your unsupported 32-bit Mac
To conclude, SFOTT can help you prepare for installing OS X Mountain Lion, Mavericks, or Yosemite on unsupported Mac computers.
The overall procedure is explained in detail by the script’s developer, but you still need to judge on your own if your Mac can support the OS or not.
