Resolved OS X Yosemite on Unsupported Macs [Guide]

[lazygatto]

Can't install on MacBookAir 1,1
Always just reboots into 10.7.5
If I try make USB with MPF and trying to install on formatted drive - MacBook just don't booting up. Hanging.
Tried both methods with OS X Extractor and MPF. No luck
Any help would be great.

PS. Maybe I do wrong trying method 1. Am I need to replace boot.efi on both - USB install drive and Partition where 10.7.5 installed for now? Didn't get this point from how-to.

Anyone know where I can get a copy of the Yosemite.app? I don't have a supported mac so..

Hi Everyone,

Hope you guys are all well.

Quick question, got a late 2006 Core 2 Duo iMac with a Geforce 7600GT inside currently running Mac OSX 10.8.5 through MLPostfactor 0,3.

I have now been following all the blogs (from Wayne in the past when he launched MLPostFactor, then from Osx Hackers with both methods). I have the impression that MacPro's are currently supported to run anything above 10.8. This being said can anyone tell me if it is possible to run Mavericks or Yosemite ( or even El Capitan) on my machine and use it normally? If there is one solution I would be more than happy to give it a try.

Your reply would be very much appreciated as I have to be honest and get a bit lost with all the possible solutions that are half working or no graphical acceleration; no USB; etc…. MLPostFactor was very easy to perform and runs now like a charm although a lot of apps start losing the support for 10.8 hence this question.

Thank you very much in advance!

Hey guys,
I'm new to the "Install OSX on unsupported Macs"-game and spent the whole day yesterday trying to install OSX Yosemite on a MacBook 4,1 from 2008, which I upgraded to 3GB of RAM and a SSD. Unfortunately, neither the SFOTT-tool nor performing the steps outlined by atvusr in the 2nd post worked despite trying it multiple times. More specifically, I was not able to create a bootable USB Drive even though I followed the instructions by the letter Has anyone of you guys ever successfully installed OSX this way? If yes, which steps did you perform?
Cheers,
Daniel

It's me again..... Finally I tried again to install it on my Macbook 4,1. I tried to install in a partition on the internal hd first. Everything good till when I have to boot from the Recovery hd created from Postfactor. When I click start to install I get an error message about some missing files and directories. I tried to make an Usb installer. Everything good till the creation of the installer. Rebooting from usb the Yosemite installation starts but, after few seconds I get this strange error: "impossible to install Yosemite because is not the right environment". Someone got this error message? From what it depends?
I tried Yosemite 10.10 first and then 10.10.4.
I got the torrent links through mactorrentdownload.net and maybe my issues are related to something wrong in the installer apps. I tried with my Macbook Pro to get yosemite on app store but is not available anymore.
Anyway, even if I'm not an expert, I don't think that is an installer problem. That error about " not right environment " maybe is about the destiantion hd for Yosemite.

If someone can help me I will appreciate a lot.

I wait some suggestions. Any help is welcome.

Thanks to all in advance.

 

[Sunapeelakers]

anyone able to download macpostfactor? Everytime I try, it doesn't complete.

 

[lazygatto]

Sunapeelakers, you can get it from my cloud. Here is a link.
But it doesn't work. It stops with message "Waiting you click Skip Ad", but Skip Ad not showed anywhere...

 

[Sunapeelakers]

Thanks Lazygatto, I actually found a copy of it on their website that completed the download for me. I went through everything and got Yosemite running pretty smoothly.. only to find out you can't run Xcode on Yosemite... *****.

 

[lazygatto]

Sunapeelakers, did you run MPF on your macbook 4,1 or you prepared flash within another mac?
And how you managed with "Skip Ad" screen? Or it is working already?

 

[Sunapeelakers]

When I got to "skip ad" I had to wait a sec, and it showed up. I installed it directly on the mac using MPF.

Thank you very much

i just install directly on my macbook... not via usb..
put OS X on application folder and running MPF normally..
it took a very long time to installed (more than 30 min)..
reboot and choose yosemite partition
follow instruction of OS X to installed normally (it will set primary startup after reboot)

i'm still searching the kexts supported on my mac but it's very hard to find it..

I used Kext Utility, dragged the AppleHDA.kext over to it, let it run its thing. After it completed, i restarted the computer and it worked like a charm.

For several monthes I could install with MCPF 1.0.1 Mavericks on my MacBook 4.1 early 2008 but not Yosemite.
Somehow two weeks ago I managed to make with MCPF in an external USB stick an installer for Yosemite and afterwards repeated MCPF this time choosing the inner drive also for Yosemite.
I cannot explain it at all but the combined USB stick installer plus the inside installation did the trick and I could finally have Yosemite.
However I had not used the latest 10.10.5 but instead 10.10.4 and by updating I lost the built in microphones and built in speakers.
By runnig the sound kext from the package downloaded with the Extractor, the AppleHDA, after rebooting I had again in and out sound.
Even a security minor update forced me afterwards to repeat the sound kext installation.
I believe I saw in a post a terminal command which should avoid those updating problems if I am not wrong.
Ed
P.S. I do not have the special recovery partition I had with Mavericks which allowed to Rehack if necessary. Therefore for precaution I made a clone with CarbonCopyCloner in case I might need it.

I thank you very much for your answer. But it doesn't work for me. I tried with 10.10.4 and 10.10.5 and it is the same results.
As you explained, I tried with an usb, with the inner drive and with both, but it doesn't work for me... With the usb when I click on install after the apple screen reboot, a few seconds later they said me that their is an error that they don't know. And if I install on the inner drive, after the apple screen reboot their is a message which explains that it doesn't work in the properly environment...
What is strange is that it is working for Mavericks but not for Yosemite!
I have a MacBook 4.1 and MPF 1.0.1. Maybe it will be solved with MPF 2.0 but I don't know if it is in project!
So I don't know what can I do know!!
Thank you

 

[MagicHAM]

I have that same experience with my 2007 64bit Mac mini, Mavericks installs awesome with Mac post factor , but when I tried with Yosemite it throws up a message at th4 install screen saying your app is not running I. The proper environment.

Probably because the 64bit professor doesn't want to play nice with it, in my face...my guess Mavericks is high I'm gonna get this Mac mini to go.

Unless someone can interpret the message I received.

hello LeGreekProvençal
As I told you, I had the same experience as you.
I had Mavericks as a result of MCPF 1.0.1 even if I chose Yosemite and this happened every time I tried.
After several monthes I came to the conclusion that my mac "decided" how far it can be hacked and that Mavericks was from the hardware side the newest OSX possible.

However I made a couple of weeks ago again a USB stick installer with Yosemite and it worked to the end.
Then I left the USB stick connected and did the installer this time inside.
Usually external installations told me at the end of a supposed "success"and asked to "reboot" while installing internally ended with a failure notice.
The reboot option for any USB external installer however did not work and a manual restart commanded by me brought me to the info shield of Apple that you know that it was not the required "environment", just like in your case!

When I rebooted this time however I was surprised that the reboot function now worked and even more surprised to see the begin of a Yosemite installation with the large all grey X instead of the previously always found Mavericks installation with a green X.
I cannot explain it but somehow Yosemite was now installing.
Since Yosemite is one of the 3 options and there were reports of other people (including the owner of the server hosting OSX Hackers.net, Isiah Johnson aka TMRJIJ) who managed using a MacBook 4.1 to have Yosemite running, it shouldn't be impossible.
However, as I also mentioned, the special hacked Recovery Partition unfortunately was not installed in my mac.
Therefore I can not rehack the system, which was very useful after any downloaded update (even a security minor update provided by Apple) at the time I had managed to have Maveticks running.

I can only encourage you not to accept defeat.
Try the double way I did again and again, and leave the USB stick installer plugged in even if you do it internally.
Then maybe you once boot on the USB stick and see what happens.
Or you reboot on the inside drive and see what happens.

I suppose that if you try again and again... at a certain moment it might work.
Unfortunately I know no more than the experience I lived through but not the reason of all the many Mavericks of past monthes and suddently the succeeded Yosemite.

Don't give up!
Good luck!
Ed

P.S. TMRJIJ is not the author of MCPF, so the chances to have one day. a MCPF 2.0 are not very high since he is the only one still working in "unsupported" macs...AFAIK.

EDIT
P.S.2. In the "Macbook" section of this Forum there is a post from somebody who says he installed Yosemite in a Macbook 2.1 using SFOTT, with a detailed explanation how to do it.
Although of course it doesn't apply exactly to a (differently built) Macbook 4.1, he includes links to a download package of different Yosemite sound and sight drivers, which (maybe) could be useful for you one day... I would download them and keep them...who knows?

Hello im new here, i have a macbook 4,1 with 3gb of ram and a 2,4 core 2 duo procesor im stuck in 10.7 os x im not able to install yosemite coz' MacPostFactor stucks at "waiting for administrator rights" and i wait for a few hours and nothing happened plz help me i do the same with Mavericks and Mountain Lion and nothing happened just the same

 

[jaysoncisme]

Well, I'm glad I'm not alone. For several days I've tried multiple attempts at installing Yosemite and/or El Capitan on my late-2007 'BlackBook' 3,1 with 2.2 Intel C2D, 4gigs of RAM and an SSD. No dice, and I have literally spent hours on end meticulously following every install instruction on various forums. I've pretty much accepted that Mavericks is all I can do (which is running pretty well minus a few annoyances.) Interestingly, Mavericks installed pretty easily by simply using MPF and adding the Extractor for the kexts & utilities post-install.

If anyone knows of a workaround to get Yosemite or El Capitan on MacBooks like mine, I'd love to hear it. I've tried every boot.efi I could find to no avail... always just ends up booting back into the 10.7 partition.

Strange that waiting for administror rights.
Are you doing it as an administrator?
As you can read in my post above yours, MCPF 1.0.1 made in my Macbook 4.1 no problem as long as I went up to Mavericks.
Yosemite did not work during countless efforts in several monthes until I used MCPF to create an USB stick as Yosemite Installer and repeated MCPF but this time inside. A double way.
There must be something in the configuration of the Macbook where you have no administrator rights and you should check that and correct it,
The tool MCPF itself cannot be the reason in my opinion.

El Capitan is in my opinion to ask much too much of a Macbook 3.1.
Up to Mavericks my MB 4.1 didn't make problems by using MCPF 1.0.1.
Yosemite however was a very long trial and error period until somehow it worked as described in my post above.
However my Macbook is a generation abead of yours.
You should forget El Capitan in my opinion and try first Mavericks to see how it works.
Remember that you must take care of sound, of wi fi, of the isight web cam and so on.
A new desktop without working components is not a useful new OS.

[FinderSpyder]

What a chore it was getting Yosemite on a 2007 White old MacBook I have here. Thanks so much for everyone posting here, it is greatly appreciated, and it helped me get it done.

However, I can't get sound to work on mine at all. I used some Kexts on the first post, maybe i did it wrong??? but I could not get sound to work at all. I had the microphones coming in through the speakers and for a little bit the headphones working only.

lol, Do I have to start over from scratch? Maybe I used the wrong kexts or something?

Thank you for your help!!!
I succeed to install Yosemite with that tutorial:

And it works very well!
But as with Mavericks, I can't change the brightness, videos doesn't word on vlc for example...
And for the sound I use the kext from extractor !

I found that Quick Time was fine to see and hear MP4 videos since VLC gave me only the sound track.
For avi videos I use the video player which comes and can be downloaded with the peer to peer application Vuze.
It avoids the need to convert avi videos to MP4 with a video converter application.
Regarding the brightness touches, they don't work but one can live with it.
There is a free tool in the App Store called Brightness Slider. Unfortunately it runs in the Terminal, so that to change the brightness the Terminal must be open. If you need less brightness it places a small icon on the title bar as long as the Terminal is open but disappears afterwards.
