- Hack Mac OS X Lion to work on unsupported Core Duo & Core Solo Macs Apr 8, 2011 - 34 Comments Mac OS X 10.7 Lion Developer Previews 1 and 2 currently do not install on older Macs with unsupported Core Duo and Core Solo hardware, but by performing a simple hack you can get these machines to boot Lion.
- My situation: I own the following unsupported Macs I want to run 10.9 Mavericks on: 2006 Woodcrest Mac Pro 1,1, and two Late 2006 Woodcrest Xserve 1,1s. I love these three systems.
- OS X Mavericks on Unsupported Macs. MacOS Extractor, OS X Patcher, 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.
- Then ML Post Factor came and enabled installation of Mac OS 10.8 on unsupported, legacy Intel Mac's. The same guys are currently making MacPostFactor for Mavericks, but until it's out, here's copy/paste of a guide from Macrumors, together with links bellow!
Attempting to install Catalina on an unsupported Mac is in no way supported by Apple, and you are doing so at your own risk. MacRumors cannot be held liable for any data loss or damage as a result.
Update 2019-05-02: For those of you who want to install macOS 10.14 on an unsupported Mac,check this post.
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:
- Sleep mode – not working at all – leave on or shut down
- The build-in web camera – “works” but not as it did in 10.7, I think
- 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:
- A USB Memory, 8GB or larger
- 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.) - SFOTT: I used version 1.4.4 which is currently the latest stable
- 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.
How To Install Mavericks On Unsupported Mac
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:
- Video Drivers – and in the case of my MacBook2,1 the unofficial ones mentioned
above may be good enough - 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. - 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.
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.
Sidecar is that spiffy new feature that allows you to extend your Mac desktop to an iPad. It’s cool but only officially supports the following devices;
- Any 27-inch iMac from Late 2015 or newer
- Any iMac Pro
- All MacBook Pros since 2016
- 2018 MacBook Air
- Early 2016 12-inch MacBook (or newer of course)
- 2018 Mac mini
- 2019 Mac Pro
Here’s the thing, those limitations are set based on performance of the machine. The /System/Library/PreferencePanes/Sidecar.prefPane actually shows support for a couple of keys that allow you to use Sidecar even if your device isn’t one of these. Buyer beware though, if you end up with performance issues then run the same commands swapping out true with false and reboot.
First, we’ll set the AllowAllDevices key in the com.apple.sidecar.display defaults domain too true. This will enable the preference for all computers that can run macOS Catalina (otherwise you won’t have the Sidecar.prefPane and supporting frameworks).
defaults write com.apple.sidecar.display AllowAllDevices -bool true
The preference pane was hidden, so we’ll go ahead and unhide it (I’ve found this optional with a reboot, but I’m not patient enough to reboot these days!). To do this we’ll write the hasShownPref key into the same defaults domain as the last command and set it to true:
defaults write com.apple.sidecar.display hasShownPref -bool true
Install Os X Mavericks On Unsupported Mac
After a reboot the preference pane should appear as usual, but you can open it manually in the meantime using a simple open command followed by the path to the .prefPane:
open /System/Library/PreferencePanes/Sidecar.prefPane
This doesn’t allow you to use any old iPad though. Sidecar supports the following iPads:
- iPad Air (3rd generation)
- iPad mini (5th generation)
- iPad (6tth and 7th generation)
- iPad Pro 12.9-inch (1st and 2nd generation)
- iPad Pro 10.5-inch
- iPad Pro 9.7-inch
If you want to use an unsupported iPad, check out https://github.com/pookjw/SidecarPatcher.
To then use AirPlay:
- Click on the AirPlay icon in the menu bar on your Mac or that Sidecar Preference Pane (Sidecar.prefPane).
- Click on the iPad.
- Drag a window to the iPad.
You can also mirror instead. In that case just click on the button to mirror. You should then have the “Move to <NAME OF IPAD> iPad” option when you click on the green jelly (the green circle in the top left corner of the title bar). That button is your buddy. As is the sidebar you see on the iPad. There you have options to show the dock, show a keyboard, undo, etc.
If all this causes performance issues on an older unsupported computer, run this command to undo it (or just delete the keys):
defaults write com.apple.sidecar.display AllowAllDevices -bool false; defaults write com.apple.sidecar.display hasShownPref -bool false
Any other tips on Sidebar, or if you figured out how to use any old iPad, feel free to comment!
