Resolved OS X Yosemite on Unsupported Macs [Guide]

[guialvim]

Macbook white late 2007 3,1 here, now with Yosemite 10.10.

Everything working fine here, but the following:

• Cannot update to 10.10.5, even using the patchers provided on osxhackers.net. Booting after upgrade (itunes, 10.10.5 and recovery) goes to a blank screen with a crossed circle.
• Brightness of screen cannot be adjusted
• Is it ok or recommended to use nosleep? What are the issues if macbook sleeps? (as the brightness cant be lowered and monitor doesnt 'rest')
• Sad to not be able to watch youtube or vimeo properly.

0.5 - Edit: Also before you update you need to uncheck one of the Apple's updates - go to AppStore and see contents of package that it want to install. There is something like "Security Update of Recovery Partition 1.0" or something like that - uncheck it, you don't need it and this update changing things on recovery partition (whick is specially prepared for unsupported machine) so..well you've seen what happened when you kept it checked.
1. After update you need to restart your MacBook holding Alt/Option key then choose Recovery drive from available drives menu (you should see 3-4 drives :With OSX Lion, Recovery for Lion, OSX Yosemite and Yosemite recovery).
get into recovery drive which is OSX Hackers recovery and hit "Rehack". because update changing some files and things in system you need to rechack it. After any update of course.
2. Brightness cannot be adjusted - as I know for this moment there is no solution for this issue.
3. It is ok. You can also manually set monitor to not go to sleep. What are issues? One, very simple but annyoing. Your computer will sleep all the time until restart. Yeah after going to sleep it cannot wake itself, don't know why. You need to restart to use your mac normally again.
4. That's strange. Have you installed newest Intel X3100 kexts from OSX Extractor? Also, what browser you use?
I watch some videos in Safari, Firefox and Chrome. In my opinion best playback was in Firefox with video set at 480p/720p. Safari also had good playback but only in 480p as i remember.
I was able to play some older games because they do not need supermassive and complicated instructions.
And I was pretty suprised when I was able to edit photos and draw in Photoshop CS4 without any problems.
Editing videos and rendering in Final Cut Express was also possible, takes a little longer than for ex. on 10.6.3 but it's working. Thanks OSX Hackers! Hope that you will develop GMA 950/X3100 kexts to perfection! Also waiting for repairs to MCPF 2.0.1 because i want to upgrade my stock Lion to 10.8 (because of perfectly working kexts and everything I think this is good to move base system one up )

Thanks, s4keru!

I've noticed Safari is better for YouTube. I use Chrome as my main browser, it is a no go for YouTube. I will try Firefox, as you suggested. Also, Opera.

About Adobe things, I have the paid subscription for all apps but was affraid it was not going to work. I will give it a try. I use mainly photoshop and after effects.

Thanks again.

No problem
You shud also remember that sometimes only older things can work. For example I tried Ps CS4 because as you can find on official Adobe sites this version of Photoshop do not need a super-duper graphics card to work properly (your graphics just must have 16bit color depth minimal and monitor minimal resolution must be 1024x768). Only for some advanced functions you need Shader Model 3.0 and OpenGL 2.0. Also Final Cut Express is old as Ps CS4 is (both from 2008), and they do not need super graphics or CPU to work fast and properly. Remember that OSX Hackers kext's are still in development and some things work perfect and others do not work completely.

It is going to explode!

Whoa man im impressed with that! How fast it works? What functions are unavailable? Is your Mac going super-hot when using CC 2015?
Also i found that editing software like newer iMovie and Final Cut Pro X will not work because of lack of Quartz Extreme support. And also Adobe Premiere CS3 do not work for me, don't know why it crash after splash screen (program loads for a second and then it crashes)

I just use for basics and it is working. I use after effects more but I need to update to 10.10.5 (got a message when trying to open it, but it is installed, also Media Encoder CC 2015.3) yet and I'm affraid to do. hehehehe It is expectably laggy (advanced english for me here) but workable. It can be annoying but I'm not going to use that way. I open a lot of chrome tabs and this already is heavy for the machine. I don't have money to buy a newer Mac (and I'm tlking about Brazil, prices here are absurdly high), so for now I'm good. Hoping OSXHackers get full functional graphic drivers for my GMA X3100.

update: 3D and 2 filters don't work on Photoshop (need at least 512mb of vram. don't know what that is)

VRam is abbreviation of Video Ram which means that it needs a graphics card with built-n minimum 512 megabytes of video ram.
Unfortunately Mac computers are expensive in many countries around the world. For example I'm from Poland and here this newest ultrathin MacBook 12" Retina in cheapest version in our currency costs 6299 PLN (in US Dollars it will be about 1650$ - in US the same Mac costs 1299$) when average salary in Poland is about 1600-2000 PLN (420$-525$ in US Dollars). So statistical Polish man if he want to buy a new Mac need to save his 3 and a half salaries in 100% which is IMPOSSIBLE. This is why in Poland people often buy used or refurbished older models, for example Late07-Mid09 Macs that are not too expensive to buy (people sells them for 400-1000PLN which is about 100$-300$), and that's why I believe in OSX Hackers so much and I pay respect to all their work. Also I'm trying to help people here with all the knowledge that I have and testing some software for them.

Same here. Minimum wage $880 (aprox 250usd) / month. newest Macbook Pro 15" i7 16gb ssd 512gb $20.999,00 (yes, 21 thousand Brazilian Reais (aprox 6000usd), but we can't convert because we receive in our currency. 21K where the minimum wage is 880/month, average R$2.200/month. 10 months to get the best one, no eating, living, nothing hahhaha It is estimated we spend 6 months of the year to pay taxes. Yeah. Let me get back to my R$1000,00 Macbook White 2007.

Yeah, I understand this entirely.

But hey look at it from this point: In some years those Black and Whithe Macs will become super rare Also look how much "hipsters" we are when using those classic and still ass-kicking machines

Also sorry you all for little offtop here ^^"

Hello I'm french user, sorry for my bad english...
I've installed Yosemite 10.10 with MCPF on macbook early 2008 with X3100, all is allright.
I've updated to 10.10.5. After I've replace the boot.efi of 10.10 to 10.10.5 and all is fine except the sound...
I've tried to reinstall the X3100 kext but nothing, I've tried the voodoohda 2.8.8 but I've some noise after the install...
Have you an idea to resolve the problem?

Try going to system preferences>sound there will be probably checked "mute" option. Uncheck it. Maximize the "Output Volume" switch, also try changing output device. This work for me everytime I install Yosemite on unsupported Mac.

I've looked on system preference and I've not output peripheral audio... I think the update have change the appleHDA kext and my peripheral is not detected... If you have solution I take it !

 

[TopHatProductions115]

Depending on the computer used and the procedure employed the RESOLVED in the title might be a bit too optimistic...or just too early judging by all the following posts, with all the credits very well deserved by the creators of these wonderful tools! Thank you very much TMRJIJ!!!!!​

***************************************************
Good to remember if you use a tool like MCPF to install an "unsupported" newer OSX.
Keep a bootable clone of the original "supported" OSX of that computer with its original unhacked Recovery Partition, for instance in a USB key or an external drive. The "special" Recovery Partition ("OSX Hackers") created by the hacking tool in Mavericks can be used for rehacking (if needed) or for doing again a "clean install' of the newer hacked system. However it doesn't give you access to a Time Machine recovery as found in a normal Recovery Partition.
(Sometimes Time Machine refuses to start and work normally from inside the hacked new OSX).
The original kept "old" Recovery Partition will allow you to boot from it and restore the newer system (if needed) from a Time Machine back up of it.
************************************************
A remark for people trying without success to install Yosemite through MCPF 1.0.1
I tried it for several months without success. Mavericks worked in my MB 4.1, early 2008, Yosemite not.
Then one day I run this tool choosing Yosemite and directing it to an external USB stick as installer, and afterwards repeated the Yosemite choice but this time pointing to the inner drive of my MB 4.1, leaving the USB stick installer plugged in. A double procedure with MCPF 1.0.1.
For unknown reasons to me, a reboot allowed me suddently to begin to install Yosemite.
I don't know if it might work for others users or for other unsupported macs but in dispair maybe you give this double procedure a try.
I later succeeded to upgrade to the last version of Yosemite 10.10.5 and to install a security update.
However I had to use each time the AppleHDA kext of the OSX Hackers kext package to have again recognized the built-in microphone and speakers, "disappeared" after any update.
I don't have unfortunately the patched special Hackers recovery partition in case I need to rehack it, as I had with Mavericks, so I keep bootable clones for safety.
****************************************************
A suggestion: MPEG Streamclip, a free, non further updated application, plays some"avi" movies in an hacked Yosemite, while VLC and other players only give the sound track. If this suggested player doesn't work with a certain "avi", the HD player, part of the P2P application "Vuze" always does in my experience.

Warning: MacPostFactor 2.0.1 doesn't support macOS 10.12 yet.

OS X Yosemite on Unsupported Macs
OS X Hackers

OS X Extracter 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 Yosemite.

MacPostFactor works for Mountain Lion, Mavericks, and Yosemite (certain Models).
Please note that older GPU (GMA 950, X3100, X1600, X1300, X1900, 7300gt, etc.) Graphics Acceleration on Mavericks and Yosemite 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 work around for these version of OS X. Here we provide guides in Post 1 and 2 and support for Installing OS X Yosemite on your Unsupported Mac.

This first post is usually updated with recent 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 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 we don't want anything to do with them and their Mac Models. It simple don't ask Mac Pro questions to people who don't have Mac Pros . Your post will be requested to be moved to their thread.
Mac Pro (1,1/2,1) Yosemite Guide: Hennesie2000's Guide here.

Prerequisites
Tested Macs listed below. Here are the minimum requirements:
- Running 10.7 Lion
- At least 2GB of RAM.
- A copy of Yosemite in Applications Folder (Recommended from the Mac App Store)
- 15 GB of free space from USB or HDD Partition to serve as your Installation Drive.

-MacBook2,x
-MacBook3,x
-MacBook4,x
-MacBookPro2,x
-MacBookAir1,1
-MacMini1,x (C2D upgraded)
-MacMini2,x
-iMac4,x (C2D can be upgraded)
-iMac5,x (post #846 might help)

We DON'T assist with Hackintosh. All private messages/emails involving installing OS X on non-Apple hardware will be redirected to another support team.

Guide to Installing OS X Yosemite on Unsupported Macs

Method 1 - OS X 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. OS X Extractor has generally everything you need to patch OS X (There are also numerous other sources that can help).
3. Get an OS X Yosemite Installer app (Recommended from the Mac App Store)
4. Make sure your Mac meets the Requirements above

B: Start Patching

1. Install OS X Extractor.
2. After you install, there should be a Hidden Toggle in your System Preferences
3. Right click on the OS X Yosemite Installer app and click show package contents.
4. Browse to the folder /Contents/SharedSupport
5. Double-click to mount "InstallESD.dmg"
6. Open up Disk Utility in Applications/Utilities and drag BaseSystem.dmg to the lower Disk Utility side pane.
7. Click on BaseSystem.dmg in Disk Utility and select the Restore tab.
8. Set the BaseSystem.dmg as the source and choose the installation drive (formatted as HFS+ and GUID) as the destination.
9. Use Finder to browse the newly restored installation drive installer.
10. Go to the folder /System/Installation on the installation drive and delete the "Packages" alias file. It will be replaced with the actual folder.
11. Go back to the mounted InstallESD.dmg and drag the "Packages" folder into the /System/Installation folder where the alias file used to be.
12. Copy the files, ”BaseSystem.dmg" and “BaseSystem.chunklist," to the root of the thumb drive.
13. Unmount InstallESD.dmg You don't need it anymore.
14. (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:
 

    

    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)
15. Now lock the new boot.efi file
16. (for non 64 bit Macs) lock the new boot.efi with this command:


    

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


17. Copy the folder named "Kernels", (rename it so if it says "Kernel") from ‘/Applications/OS X Hackers Patch Files/‘ to the ‘/System/Library/Kernels/‘ folder on the installer drive.
18. replace the original OSInstall.mpkg in the Installation drive (/System/Installation/Packages/) with the modified one from /Applications/OS X Hackers Patch Files/
19. Next you will have to add your Mac Model to the installer. You will have to replace the files without corrupting them. Some of the files are signed so be careful not to change anything else. Make sure your changes mimics the same syntax as other entries. You may have to copy and paste the quote marks from an existing entry. If your closing quote after the boardID looks italic, you're WRONG!
20. run the IORegistryExplorer.app from the OS X Hackers Patch Files folder make sure in the top left corner IOServices is selected
21. under root select your Mac(model) -> on the right at the top copy the board-id value.
22. open in your Installation Drive, /System/Installation/Packages/InstallableMachines.plist with TextEdit and search for the last entry and replace it with your board-id value
23. open /System/Library/CoreServices/PlatformSupport.plist and do the same.
24. Great! The hard part is over. Now it's time for installation. Re-hide the hidden files with the DisAppear.app, Close the Terminal, and Close all other Applications. Take a breather and move on to the next part of the guide.

C: Installation

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

   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 Yosemite desktop boot to the install-drive again and perform the following.
Boot back into the Yosemite Install Partition
open the terminal at the top menu bar or boot into single user mode (Hold Command -S immediately afterturning on)
enter:

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

E: Install these 64 bit Kexts from the Kexts folder from OS X 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

Install the NoSleep Extension
Set the Preferences to Never Sleep on AC Adapter and Battery
Check the 'Start NoSleep Utility on system startup' setting
Your Macbook screen will never turn off unless your actually shut down your Macbook.

CONGRATULATIONS!!!

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, VLC nor DVD Player (best use Quicktime, the HD player of Vuze 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.

My computer suffers random freezes every once in a while. Mouse works but everything else don't. Restarting fix the problem.

Try restarting. If it doesn't work, be more specific about the problem.

WOW. Thats totally unexpected. Maybe a hardware problem? Try plugin a keyboard into the USB to see if it works.

Maybe try booting the original OS X CD you might have. Or try booting ANY bootable CD/DVD you can find. Windows, Linux... Just to be sure its not a hardware problem.

If keyboard and mouse works, try reinstalling the Yosemite again. I had to do it a few times before everything became normal.

The only solution would be to reinstall Yosemite then.

Are you applying all patches/ketxs properly after installation? Specifically Software Update Patch (from OS X Hackers folder) BEFORE UPDATING to 10.10.5. I think thats where the problem is.
The Recovery Patcher will patch the recovery so in case you need to boot Yosemite, it'll work. Should patch after any update to Recovery updates.

Sorry for not finding a solution but your problem is unique. Ive read ALL posts in this thread (yes, all +1200 of them) before installing Yosemite in my laptop. Make sure you're doing everything correctly.

Is it possible to install Bootcamp next to this (Yosemite) installation?

The answer is YES, following the normal procedure with the bootcamp assistant.

I have a Macbook 4,1 running with Yosemite (Tried to install El Capitan but it is a no-go for this device) with a bootcamp partition and Windows 10 on it which works remarkably well. It would give most up-to-date PCs a run for their money.

You will need the media for Windows 7 or older as Bootcamp will not receive any newer Windows version for installing on this device, but once you restart, you can use any version, including Windows 10.

If you are wandering about drivers for Windows 10, use FIRST Bootcamp version 4, the trick is you will need to install every driver separately because the bootcamp.msi installer will not start on Windows 10. Once everything is on its place, use Bootcamp's latest version, this time the bootcamp.msi file will work fine but will not "recognize" your device. Anyhow, this will install the windows bootcamp assistant and apple software add-ins (like the HFS+ drivers).
