Install Mavericks On Unsupported

 admin

Install Mavericks 10.9 to the system: Note that there are no USB 2.0 ports on the rear panel of the ECS motherboard. As needed add a header cable to bring out a USB 2.0 port to accept the USB installer device. As needed add the target hard drive to the system (and remove any other). In this video, we're going to install Mountain Lion (OS X 10.8) on an unsupported Core 2 Duo MacBook. This guide applies to the MacBook 2,1 through 4,1 and c.

How to install mavericks on unsupported mac

I have a MacBook Mid 2007 (more technically named MacBook2,1) that officially can not be upgraded beyond Mac OS X 10.7 (Lion). It is however possible to install Mac OS X 10.9 (Mavericks) on it with quite good success and not too much effort.

I want to first write what does not work:

  1. Sleep mode – not working at all – leave on or shut down
  2. The build-in web camera – “works” but not as it did in 10.7, I think
  3. YouTube-video (etc), works occationally (now worse than in 10.7, my experience)

I suggest you read the user comments to this post. A few helpful readers have shared their experiences.

What you need:

  1. A USB Memory, 8GB or larger
  2. Mac OS X Mavericks (i had the install/upgrade Application that I had myself
    downloaded on another Mac, from App Store, when I upgraded it from 10.8 to
    10.9. I always keep these for possible future use.)
  3. SFOTT: I used version 1.4.4 which is currently the latest stable
  4. Audio/Video-drivers from (not here anymore, se comments below).
    Warning, this is one of these horrible download pages where you don’t know
    where to click to get the right thing, and what gives you spyware. You
    should get the file mac-mini-mavericks.7z. Discard anything else without
    opening. The 7z-file can be opened with StuffitExpander, that already
    comes with Maverick

Making a bootable USB-drive
You first need to use SFOTT to create your bootable USB-drive (it is called “key” in SFOTT). You simply double-click on SFOTT on a Mac where you both have your Mavericks Install App and your USB-drive. SFOTT is a self guiding menu-driven application. It will take some time to make all the settings in SFOTT (it took me perhaps 15 minutes), but it was self-explanatory and not very difficult. Use the autorun mode to create the drive.

Recovery Scenario
When you install a Mac OS upgrade there is a risk your Mavericks system will not boot. When upgrading from 10.9.0 to 10.9.5 like I did, it will not boot. My impression (after reading different sources) is that this recovery is needed when upgrading from 10.9.0 (or 10.9.1 / 10.9.2) but not later. Nobody knows about 10.9.6 of course, because it is not out. Minor upgrades to applications or security upgrades should not cause need to recovery.

When Mavericks fails to start you need to “re-Patch” using SFOTT. I installed Mavericks on a separate partition, side-by-side with Lion, so when Mavericks failed to start my computer automatically started Lion instead and I could run SFOTT in Lion to re-Patch my Mavericks system.

If you can not do side-by-side you can start from your SFOTT-key (which you still have) and instead of installing Maverick you start the Terminal application. Find the SFOTT.app on the key, and find SFOTT.sh inside SFOTT.app. Run SFOTT.sh and you can re-Patch your broken Mavericks system. I did the entire procedure on my working Mavericks just to test it, and it seems fine.

There is if course no true guarantee that a future Apple upgrade will not break everything completely.

Installing Mavericks
Installation of Mavericks from the USB-drive is very standard. To start the computer from the USB-drive, hold down the “alt”-key (not Apple-key, not ctrl-key) while starting the computer. Choose SFOTT and proceed normally. After about an hour you should have a clean 10.9.0 Mavericks with network/wifi working. Video will work, but with problems (try Safari, and you will see), and Audio will not work.

Upgrade Mavericks
I used App Store to upgrade Mavericks to 10.9.5. That works just fine, until Mavericks fails to start (I ended up in my old Lion system on a reboot, if you have no other system installed your computer with probably just not start). This is where you need to recover your system using SFOTT.

Fixing Audio and Video
The 7z-file I referred to above contains Audio and Video drivers. You run the application “Kext Utility” and the you drag the contents of the folder Extensions into the Kext Utility, and it will install the drivers. There is a folder with “optional wifi drivers”, I have not installed those because wifi has been fine all the time for me.

The MacBook2,1 has Intel GMA950 Video, and there are no supported 64-bit-drivers for Mavericks. The drivers I suggest you to install are supposed to be drivers from a public beta of 10.6 (Snow Leopard) that Apple once released. They seem to work quite fine for me though. And not installing them is worse.

I suggest you upgrade to 10.9.5 before fixing Audio and Video. I guess a later Apple-upgrade could break Audio and Video and require you to reinstall drivers.

Problems booting the SFOTT key
I first created the SFOTT key using the SFOTT beta (that is also supposed to work with Yosemite), and I used System Preferences/Startup Disk (in Lion) to start the installion. This failed and my computer just started up in Lion.

I then created the SFOTT key using 1.4.4, AND i restarted the computer holding down the alt-key. This worked. This key also later worked when I used System Preferences/Startup Disk (in Mavericks) to choose startup drive.

Driver Problems
There are open source Audio drivers called VoodooHDA. I installed those ones with success, but audio volume was low. I tried to fix with no success. Later I found the drivers I referred to above and that I recommend.

I found another download for what was supposed to be the same Video Drivers. But the Kext-utility did not work, and I installed the drivers by copying them directly into /System/Library/Extensions and this gave me a broken unbootable system. I don’t know what went wrong, but I recommend the drivers I linked to.

Video/YouTube Performance
Some videos seem to play perfectly, others dont. I had problems with 10.7 too.

Background and about SFOTT
There are several Apple computers that can run 10.7, that have a 64-bit processor, but that can not officially run 10.8 or later. There are a few issues:

  1. Video Drivers – and in the case of my MacBook2,1 the unofficial ones mentioned
    above may be good enough
  2. 32 bit EFI. Even though the computer has a 64 bit processor, the EFI, the
    software that runs before the Installer/Operating system, is 32 bit, and not
    capable of starting a 64-bit system.
  3. Mavericks does not believe it can run on this hardware.

As I understand it SFOTT installs a little program that 32 bit EFI is capable of starting, and that in turn is capable of staring a 64 bit system. Also, SFOTT patches a few files so Mavericks feels comfortable running on the unsupported hardware.

You can do all of this on your own without SFOTT. SFOTT “just” makes this reasonably easy.

Can I Install Mavericks On My Mac

There are plenty of forums, tools and information about running Mac OS X on unsupported hardware (also non-Apple-hardware: a Hackintosh). Those forums of course focus a lot on problems people have.

Yosemite
It is supposed to be possible to install Yosemite in a similar way. SFOTT has a beta release for Yosemite. For my purposes going to Mavericks gave me virtually all advantages of an upgrade (supported version of OS X, able to install latest Xcode, etc).

Conclusion
In the beginning of 2015, it is not that hard to install Mavericks on a MacBook Mid 2007, with a quite good result. I have pointed out the tools and downloads you need and that will work.

How To Install Mavericks On Unsupported Macs

MacPostFactor (formerly known as MLPostFactor) is a simple macOS app designed to help you bypass macOS' hardware limitations and install Mountain Lion, Mavericks or Yosemite on devices that are NOT officially supported.

If you need to install macOS Sierra or macOS High Sierra on an unsupported computer, you need to use the macOS High Sierra Patcher tool.

MacPostFactor will prove to be useful if you are using an older Mac model, but you still want to take advantage of the capabilities provided by Apple's latest operating system releases.

However, keep in mind that the MacPostFactor application still has its own requirements, such as the presence of a copy of OS X Mountain Lion, Mavericks or Yosemite in the Applications folder (must be available as an .app file), and 2GB of RAM. In addition, the installation procedure requires your attention and you will perform it at your own risk.

Carefully follow the installation instructions to deploy macOS on older Macs

To start the installation process you first have make sure that you have MacPostFactor and the macOS installer app in the Application folder. Next, you have to launch MacPostFactor, accept the EULA and then choose where you want to install OS X and what flavor of it you want to install on your older Mac.

It is important to understand that with the help of MacPostFactor you can install OS X Mountain Lion on MacBook2,x, MacBook3,x, MacBook4,x, MacBookPro2,x, MacBookAir1,1, MacMini1,x (C2D upgraded), MacMini2,x, iMac4,x (C2D upgraded), or iMac5,x Macs.

Furthermore, MacPostFactor also helps you install OS X Yosemite and Mavericks only on Macs with upgraded graphics such as the Mac Pro and Xserve.

After you click the Install button, you have to wait until the process ends and then reboot the Mac to complete the installation.

Simple to use wizard tool designed to help you install the latest macOS releases on unsupported Macs

MacPostFactor is a free and powerful macOS app which proposes a solution for people that own older Macs that are not supported by Apple's Mountain Lion, Mavericks or Yosemite operating systems.

However, as long as your Mac meets MacPostFactor's requirements, you can effortlessly install the Mountain Lion, Mavericks or Yosemite OS X releases, but you still have to keep in mind that you are performing the installation at your own risk.
