OS X Mavericks on Unsupported Macs

macOS Extractor and MacPostFactor are apps that guide you through patching and installing OS X El Capitan (10.11), Yosemite (10.10), Mavericks(10.9), or Mountain Lion (10.8) on your older Mac. This thread focuses on OS X Mavericks.
MacPostFactor works for Mountain Lion, Mavericks, Yosemite, and El Capitan.
Please note that older GPU (GMA 950, X3100, X1600, X1300, X1900, 7300gt, etc.) Graphics Acceleration on Mavericks, Yosemite, and El Capitan is not supported yet but this thread consists of many graphical workarounds.

Installing on these models may cause them to have graphical issues as stated in these pages. Kexts are provided to help a little bit.
OS X Extractor is somewhat for more advanced users and should only be used as an alternative to MacPostFactor. This thread consists of members prominent in these patches that can help you solve your issues. Please do not hesitate to post if you have questions.

Apple History

OS X 10.6 Snow Leopard was the first OS X version with optional support for a 64-bit kernel, allowing booting either with a 32-bit or 64-bit kernel. However, Apple did not support booting the 64-bit kernel in Macs that shipped with EFI32 firmware, even if they had 64-bit processors capable of running the 64-bit kernel. When Apple dropped the 32-bit kernel entirely from OS X, starting with OS X 10.8 Mountain Lion, EFI32 Macs no longer had an Apple-supported mechanism to boot newer OS X versions.

Fortunately, we have found a workaround for this version of OS X. Here we provide guides  here and support for Installing OS X Mavericks on your Unsupported Mac.

This page is usually updated with recently summarized information, updates, and more solutions.

For those who have 2006/2007 Mac Pros, you may be best suited to using Mr. Zarniwoop's Thread here. The MCPF and macOSE projects are not affiliated with them. We will not contact them either. Confrontation has occurred both publicly and privately in MacRumors, the site, and other forms of communications and we don't want anything to do with them and their Mac Models. It’s simple, don't ask Mac Pro questions to people who don't have Mac Pros :p. Your post will be requested to be moved to their thread.Mac Pro (1,1/2,1) Yosemite Guide: Hennesie2000's Guide here.

Guide to Installing OS X Mavericks on Unsupported Macs

Method 1 - macOS Extractor​

ANY HARM OR DAMAGE CAUSED BY THIS GUIDE HAPPENED UNDER YOUR OWN RESPONSIBILITY!IF YOU HAVE ANY REGRETS ABOUT DOING THIS TO YOUR MAC, YOU PROBABLY SHOULDN'T DO IT. IF YOU ARE QUESTIONING WHETHER IT IS WORTH IT, YOU SHOULD DEFINITELY NOT TRY THIS.
PLEASE READ THIS GUIDE BEFORE ASKING QUESTIONS? WE HAVE TOO MANY EMAILS AND SKYPE MESSAGES TO ANSWER AND CAN'T BABY YOU THROUGH THIS ONE STEP AT A TIME. IF YOU CAN'T FIGURE YOUR WAY AROUND OS X, YOU SHOULDN'T BE DOING THIS.

Be sure to have root privileges (administrator password) as OS X will prompt you for this on some stage.

A: Preparing The Installation Drive

1. Make a BACKUP of your system if you can.
2. macOS Extractor has generally everything you need to patch OS X (There are also numerous other sources that can help).
3. Get an OS X Mavericks Installer app (Recommended from the Mac App Store)
4. Make sure your Mac meets the Requirements above
5. A USB or Secondary Partition to put the patched Installer (A Installation Drive for reference)

B: Start Patching

1. Install macOS Extractor.
2. There should be a new drive appearing on your Desktop called ‘Mac OS X Install ESD’. Don’t worry about that. The AutoPatch Tool will unmount that when its done.
3. Go to Applications/OS X Hackers Patch Files and run the AutoPatch package.
4. During the AutoPatch installation. Select the USB or partition (Installation Drive) that you want as the installer. (No, this is not the Mac OS X Install ESD) WARNING: DO NOT SELECT YOUR CURRENT PARTITION (i.e Macintosh HD)
5. (for non 64 bit Macs) Unlock and Replace the boot.efi files located in /System/Library/CoreServices and /usr/standalone/i386 with the copy provided in /Applications/OS X Hackers Patch Files/Boot EFI/ or from here . To Unlock it, use the Terminal app in Applications/Utilities/ and enter the command:

Code:
sudo chflags nouchg /Volumes/OS\ X\ Base\ System/System/Library/CoreServices/boot.efi


(If you receive an error, go the that directory and find the boot.efi. Then in the Terminal, enter 'sudo chflags nouchg ' and drag the old boot.efi in the window. Press Enter)
6. Now lock the new boot.efi file
(for non 64 bit Macs) lock the new boot.efi with this command:

Code:
sudo chflags uchg /Volumes/OS\ X\ Base\ System/System/Library/CoreServices/boot.efi
  

C: Installation

1. reboot your Mac holding option (alt) key.
2. If the installation drive boots you back to the main partition, try blessing the drive from your terminal app:

Code:
sudo bless --folder /Volumes/OS\ X\ Base\ System --file /Volumes/OS\ X\ Base\ System/System/Library/CoreServices/boot.efi --setBoot

3. select the Installation drive "OS X Base System" (and press enter)
4. when booted click install/continue until you reach the disk selection menu, select you main drive (probably Macintosh HD) if you are sure about it, else select another empty drive (at least 15GB for testing/bigger if it should be a secondary system)

D: If Reboot Fails

(If the Mac does not reboot to the Mavericks desktop boot to the installation drive again and perform the following.

open the terminal at the top menu bar or boot into single user mode (Hold Command -S immediately after turning on)

enter code:
sudo rm /Volumes/[Main Drive Name]/System/Library/CoreServices/PlatformSupport.plist

E: Install these 64-bit Kexts from the Kexts folder from macOS Extractor

(These will better the graphics by a little but you will not have Graphics Acceleration. Still in beta so they may not work well)
1. Navigate in your Finder and go to the 'OS X Hackers Patch Files' folder in your Applications Folder
2. Open the 'Kexts' Folder
3. Choose your Graphics Card Kext Installer and launch it.
4. Select the Partition or Hard Drive that you are currently using the patched OS X. Install it. (Admin privileges required)
5. Restart your Mac

IF your Macbook can't wake up from sleep:

Because of lack of working Graphics Acceleration. Your Macbook may not be able to wake from a display sleep. The Kext Installer includes a NoSleep Extension and Brightness App.

Method 2 - MacPostFactor

IMPORTANT NOTES
Install MacPostFactor at your own risk. We are not liable if your computer explodes, fail to wake you up for work, lose important files, pictures, porn or simply ceased to work. Always backup your existing installation before installing MacPostFactor or install in a second partition.
We are not aware of remaining bugs...Although it has been thoroughly tested by us and our group of private beta testers, you might still find bugs in it, and if you do find one, feel free to contact us on Twitter @MLforAll & @IsiahJohnson15 or simply email me at [email protected] (@MLforAll's mail) or go to the Support Page.

Mavericks Install is EXPERIMENTAL. Try this on a secondary partition.

Supplementary Information for Mavericks 

Mavericks can be installed on all computer but ONLY Mac Pros WITH AN UPGRADED GRAPHICS CARD can use graphics acceleration as of now!

Requirements for MacPostFactor to work

Bugs (from multiple Mac Models)

1 Maps does not view the maps
2 Launchpad is somewhat delayed and choppy
3 Video don’t play in iTunes, Safari, nor DVD Player (best use Quicktime and Google Chrome)4 Notification Center is sometimes a mess.
5 Only one Screen Resolution available
6 Some Apps will have artifacts if primary using Graphics Card.
7 iMessage/FaceTime note: Most users cannot initially login to iMessage or FaceTime using their Apple ID from their Macs after installing Yosemite as a security precaution. When trying to login, they receive an iMessage Registration validation code. The solution is to contact Apple support, provide the Mac's serial number, explain that Yosemite was installed using our guide and that iMessage isn't working and provide the validation code. Apple then unblocks the Mac, allowing iMessage and FaceTime login immediately and in the future OS updates. They really don't care.
