The first post of this thread is a WikiPost and can be edited by anyone with the appropiate permissions. I wanted to make a quick guide for those who are stumbling through getting Yosemite on your unsupported Macs, namely Mac Pros and Mac Minis which are perfectly capable with some upgrades. Before you begin, if you have a Mac Pro, get a better graphics card, your default one will suck, thanks to Yosemite. The one that I am using as a stop-gap actually works fine for Yosemite, it is currently 35 (USD) on Newegg, if you want it, here is the link. Now on to the guide NOTICE: I am not responsible for erasing or breaking your Mac Continue at your own risk This works on the public release with some shoe-horning. Prerequisites: An unsupported Mac, your choice if you deem it capable or not. OS X Yosemite.app Pre-install: 1. Icoda For Os X Yosemite Download And InstallDownload and install SFOTT from the linkmirror above. Download Yosemite either from a suspicious location or from the Mac App Store (try using Mavericks Download Enabler if on unsupported Mac). Rename Install OS X Yosemite.app to Install OS X Yosemite Beta.app. Hopefully that will not need to happen in newer versions of the script. Icoda For Os X Yosemite Mac OS Extended AndPlug the USB drive into your Mac and format it as Mac OS Extended and name it SFOTT. Note: 12a only needs to be done if your Mac Pros graphic card doesnt have EFI boot. Select Select OS X Installer (5) and select In the default Applications Folder location (Faster) (1) It should work if you renamed your installer specified above. Icoda For Os X Yosemite Patch SFOTT KeyGo back to the main menu and select Create Patch SFOTT Key (4). ![]() Follow the directions there. If you have a graphics card that doesnt support EFI boot, open System Preferences on the target Mac, plug in the SFOTT USB key, and open the Startup Disk preference pane. Select the SFOTT key and reboot from the panel. If you are using a Mac with built-in graphics or your graphics card supports EFI boot, just reboot and hold down option after the chime. Your install should continue as expected. Troubleshooting: 1. The installer says OS X Cannot be Installed on this Machine: Make sure you set your machineboard-id in step 6-7. Boot into the SFOTT USB-stick. Use disk utility to repair permissions of your system. Reboot. That should do the trick. Got the general release of Yosemite, renamed it Install Yosemite Beta.app, and ran SFOTT. Enabled the Yosemite installer, and selected the above app. Selected an external drive I was willing to erase to create my bootable installer on as the SFOTT target, and selected the current computer as the system to install to (MacBook4,1 Mac-F22788A9). It appears that everything was moved to the drive correctly, with no errors. However, when I try to boot to that drive which is selectable in the Startup Manager, it fails with no visible error message and instead boots to the internal hard drive on my system. It should be noted that this MacBook currently is running Mountain Lion using the old MLPostFactor kit. Is this messing with the EFI installation for the new drive Am I missing something else in the setup process (Very frustrated here, as I wasted my entire day off trying to get this to work. Hi, I ended at this step.
