A OSXE update is recommended to assist you in installing macOS Sierra, El Capitan, Yosemite, Mavericks, or Mountain Lion on your old Mac. Also, by updating the patching software on your Mac, you can enjoy various additional features and enhanced security. Always use to the latest version.
Never download this from any other provider. All links must be from these forums or directly from our server. This is to ensure that nothing was tampered with and that you have the most reliable and tested software.
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.
OS X 10.11 El Capitan includes rootless security known as System Integrity Protection. It makes sure that System file permissions are automatically protected, and updated during Software Updates. The Repair Permissions function is no longer available and access to system files that we need to use in this guide may be locked.
For those who have 2006/2007 Mac Pros, you may be best suited to using Mr. Zarniwoop's Thread here. The MCPF and OSXE 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 OS X Hackers do not want anything to do with them and their Mac Models. For the protection of User’s property, we will not be able to actively assist with Mac Pro issues. Any questions or concerns will be redirect to the more qualifying developers.

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 THE 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 macOS/OS X, YOU PROBABLY SHOULDN'T BE DOING THIS.
THE SECURITY AND PROTECTION OF YOUR INVESTMENT TO THESE COMPUTERS ARE OUR TOP PRIORITY SO WE DESIGN OUR SOFTWARE WITH MANY ATTEMPTS TO RECTIFY ANY ISSUES YOU MAY COME ACROSS BEFORE SUCH MAJOR PROBLEMS OCCUR. NOTE: IF YOU COME ACROSS AN ERROR, IT IS BEST TO STOP THE PROCESS AT THE SAFEST CONVENIENCE AND CONTACT SUPPORT TO AVOID RISK OF DAMAGING YOUR MAC.
AS ALWAYS, BACK UP ALL DATA AND TRY THESE PATCHES ON A DIFFERENT PARTITION OR NON-PRODUCTION MACHINE FIRST.
When performing these tasks, you are doing it at your own risk. We can not claim that our software is 100% guaranteed to work. OSXE Updates may not always correct issues. OS X Hackers and the rest of the Johnson Network Community are not responsible for anything that happens to your Mac and/or other devices. We are trained to diagnose our Macs for the worst case scenario, like if the computer is unable to boot. However YOU are taking the risk and it is highly recommended to backup all your important data.
OS X Extractor 1.4.~ is mostly web based. It is a 4 MB package file (.pkg) that will download only what the user actually specifies from the OS X Hackers Server. This means that most updates are done on the server side by developers. Users can use the 4 MB .pkg to update with certain packages. Pacifist app is still supported and can download the package upon extracting the files or installing them manually from this app.
◦ macOS Sierra Support with newer Unsupported Macs
◦ Fixed Syntax Error
◦ German and Dutch Lanuage Support
◦ Installer now mounts the Installer App
◦ AutoPatch now available
◦ Addresses NoSleep Extension Issue
Some Macs may fail installation even if they meet the minimum requirements.
OS X Hackers app may crash upon starting up. A workaround would be to Go to folder "~/Library/Caches" and delete the JN4.OS-X-Hackers and in folder "~/Library/Preferences/" delete Johnson Network 4.2.OS-X-Hackers.plist
Some users may get greyed out option for their selected OS X. A workaround would be to create a touch command in Applications/OS X Hackers Patch Files/.Developers/ called in accordance to your intended OS (sierra.eboot, escap.eboot, yos.eboot, mav,eboot, ml.eboot)
The AutoPatch is designed to perform most of the manual tasks in patching the OS Installer. During the Installation process, the following is performed to the chosen partition or external storage device
◦ Kernels for Sierra may not be included.
◦ Other Kexts within the OS X Hackers Patch Files are not added with this version of the feature but will need to be added into the Installation Drive
◦ No script was included for graphics kexts. This would need to be installed manually after installing the OS.
This OS can be used with the patches and is detected by macOS Extractor. ONLY newer Unsupported Mac can install this version of macOS at this time. Current El Capitan issues for these unsupported Chipsets are still a major problem in Sierra.
◦ Early-2008 or newer Mac Pro, iMac, or MacBook Pro (MacPro 3,1 and 4,1, iMac 8,1 and 9,1, MacBook Pro 4,1, 5,1 5,2, 5,3, 5,4, and 5,5)
◦ 2008 or newer MacBook Air or Aluminum Unibody MacBook (MacBookAir 2,1, MacBook 5,1)
◦ Early-2009 or newer Mac Mini or white MacBook (Macmini 3,1, MacBook 5,2)-Early-2008 or newer Xserve (Xserve 2,1)
◦ 2006-2007 Mac Pros, iMacs, MacBook Pros, and Mac Minis (MacPro 1,1 and 2,1, iMac 4,1, 5,1, 5,2, 6,1 and 7,1, MacBook Pro 1,1, 2,1, and 3,1, Macmini 1,1 and 2,1)
*The 2007 iMac 7,1 is compatible if the CPU is upgraded to a Penryn-based Core 2 Duo, such as a T9300.
◦ 2006-2008 MacBooks (MacBook 2,1 3,1 and 4,1)
MacBook2,1, MacBook3,1 and iMac5,1 do NOT have newer SSE 4-compatible CPUs and will probably be dropped after El Capitan.
◦ This OS dropped support for Wi-Fi cards (BCM4321) used in most 2008 and some 2009 Macs. A hardware upgrade is required to get Wi-Fi functionality on these models.
◦ iMac8,1 - Volume control for the Built-In Audio device may work improperly or not at all.
◦ Macbook5,2 - The trackpad is not configurable, it is detected as a regular mouse instead limiting multitouch gestures.
This OS is supported for all unsupported Macs but requires more manual effort. The Intel Chipsets in most models are not supported and can be troublesome getting the Beta USB Kexts to work while the SIP setting with the Bootloader is still present.
We are actively working on a solution to permanently set SIP to 0x67 within the NVRAM however compiling issue between Microsoft Visual Studio IDE and The Netwide Assembler. This issue affected both MacPostFactor and macOS Extractor 1.3 and newer
All Graphical Kernel Extension have been updated with more workarounds to the lack of OpenGL 4 Support in OS X Mavericks and newer. New Brightness Control Application and Maintenance scripts have been added to the installer in order to speed up these older models. New Quicktime and Sarafi Extensions are updated to allow video playback in many different formats.
Sleep is still not supported due to its connection with WindowServer however the NoSleep Extension is active within each Graphical Kext Installer.
Note: Power Consumption has been reported as a new issue. Battery life in unsupported Mac Laptops will likely decrease significantly especially with non-Apple removeable Batteries.
The Beta OpenGL Frameworks for Mavericks, Yosemite, El Capitan, and Sierra have been depreciated. No further development will be made until the Kernel can be reverse engineered to fix the WindowServer crashes.
OpenGL Frameworks for Mountain Lion are still supported and will remain active throughout future security updates.
