SFOTT

SFOTT is a handy AppleScript tool that makes it easier for you to install OS X Mountain Lion, Mavericks, or Yosemite on older Apple computers. If your Mac has a 64-bit processor, you're good to go! But if you have an older 32-bit model, you might think you're out of luck. That's where SFOTT comes in!

What Does SFOTT Do?

Basically, SFOTT helps you create a USB drive that can install these OS versions on unsupported Macs. It's built on some cool stuff called boot.efi, developed by Tiamo over at MacRumors, and it automates the whole key creation process for you.

Getting Started with SFOTT

Before diving in, make sure you've got the following: the SFOTT app installed on your Mac, the Yosemite installer downloaded, and a USB drive plugged in (an 8GB one should work just fine). It’s super important to check all this before starting!

Can Your Mac Handle It?

If you've done some upgrades like changing your graphics card or adding more RAM, there’s a chance your older Mac could run Yosemite even if it’s not officially supported. Just remember to make that call yourself—installing an unsupported OS might cause data loss or even mess up your Mac.

Using the SFOTT Script

Once everything's set up, you can find the SFOTT script in the Utilities folder under Applications. Open up a Terminal window to see details about your computer's settings and whether you're running 32-bit or 64-bit firmware. While it's possible to change some settings around, it's best to run SFOTT directly on the target computer.

Create Keys Easily

With SFOTT, you can generate new URB or media keys for installing Yosemite either step by step or automatically—whatever suits your style!

Need Help? Check Out the Docs!

If you're looking for more info on how to use it properly, don’t forget to check out the SFOTT documentation. It’s provided by the developer and includes all kinds of useful tips! Plus, there’s a Read Me file in the archive that can help too.

Wrapping Up

In short, SFOTT is a great way to prepare for installing OS X Mountain Lion, Mavericks, or Yosemite on those older Macs. The whole process is explained well by its developer; just remember that you'll need to decide if your Mac can handle this installation.
