OS X El Capitan on Unsupported Macs

[Hasefroch]

For 10.10 ... I remember I tried also with osx-patcher, with another older version, and it worked, and I didn't have to use another Mac for this ...

But the problem is ... if you see the Julian's page ... I remember almost all the versions was deleted between last year and now :/ And I didn't save the precise version that works with Yosemite on MacBook2,1 ... I tried all the versions that are present now ... and first I also have the need to do the installation on another supported Mac and also ... we have the same problem : it reboots itself after some minutes (For El Capitan it's around 2 minutes, for Yosemite, for some reason it's around 10 minutes ...). And maybe this is also because of the buggy boot.efi that the osx-patcher provides.

Also, I see in the GitLab page that the project is archived (weeks ago aren't)

Yes i saw this, I really wanted to do this tutorial right here on GitLab (so a lot of people can discover my "solution") but no sadly :/ I understand his decision to not provide anymore help for this ... but yeah this is very difficult to do this. I needed 9 years to finally put El Capitan on my MacBook2,1 ...
And also, I sold my MacBook2,1 with Yosemite more than year ago ... and I just bought again a MacBook2,1 few weeks ago.

And I also forget ... for the fact that with osx-patcher 1.3.1 ... it reboots to another partition like immediatly when you boot on an unsupported Mac ... I just remember i saw this on the first post :

If the Installation Drive boots you back to the main partition, try blessing the drive from your terminal app:
Code:
sudo bless --folder /Volumes/[Installation Drive Name] --file /Volumes/[Installation Drive Name]/boot --setBoot

So maybe there is also something to do with this line of code ... I don't exactly remember, but I think I tried this, and it dosen't work ... So I don't know

I tried this with the Yosemite installer and "Error while getting file ID of "/Volumes/-drive name-/boot. Ignoring...

 

[Hasefroch]

I looked at the USB and there isn't any "boot" file or folder

 

[Hasefroch]

I searched and found two "boot.efi" files on the disk one at "patch/10.11" folder and one at "patch" folder

 

[AD1234567890]

Yeah you had the same problem has me unfortunalely ... Sorry but for here I didn't have the solution :/ This code was intented to use for macOS Extractor (Which I also tried, and it also didn't work ...), so this code is not the solution, but only a hint.

 

[AD1234567890]

I searched and found two "boot.efi" files on the disk one at "patch/10.11" folder and one at "patch" folder

Ah yes, this is good news (maybe ?), so maybe try to change theses boot.efi files (maybe you will have some troubles with permissions, so read carefully my original tutorial and take inspiration from this)

 

[Hasefroch]

And now I did the same command but replacing the "--file" with "/patch/boot.efi" instead of "/boot" and it directly don't appear on the boot menu

 

[AD1234567890]

Ah ok. What is the version of osx-patcher that you tried to use ? 1.2.1 or 1.3.1 ?

 

[Hasefroch]

I'm downloading El Capitan for trying

 

[Hasefroch]

1.3.1

 

[AD1234567890]

Ah ok. I would say try 1.2.1 as with this version without modifying anything I can go more further (until the installation), than 1.3.1 (when it dosen't boot at all after 1 seconds like yours). So download this, try to find all boot.efi files, replace them, boot at first the USB flash drive and if you can install don't forget to do this command : date 0115124517

Thanks! The date command is when it booted, of before booting? And I have to disable Internet?

Yes, in fact, you are on the boot menu, select the installer, choose your language, and the top on the top bar you should have an "Utilities" or similar menu where you can open Disk Utiltity, Safari, Terminal, if I remember, click Terminal, and yes you should disable Wifi because it wont stop to change the date, then type date 0115124517

And I also should note that this boot.efi, is guaranted to work only on El Capitan, i don't know if it work with other OS X versions, or even if there is an boot.efi file in existence for other versdions of OS X you if you want to install another OS X, check the concerned topic for more info

Thanks, I will try 1.2.1 on El Capitan installer (that is downloading now on the Mac, because Wifi is topped at 50mb on the mac, I'm writing this on my PC

 

[AD1234567890]

You're welcome ! No problem.

Hello, I tried with 1.2.1 with El capitan installer (long download and USB creation) and it also don't boot. I tried replacing the boot.efi on the patch and patch/10.11 folder of the USB with the boot.efi downloaded from your post (Dropbox) and also not. But I changed the command to sudo bless --folder /Volumes/-drive- --file /Volumes/-drive-/patch/10.11/boot.efi --setBoot , and now it passed, but get stuck on the (grey) Apple logo. I am waiting if it advances

 

[Hasefroch]

-drive- is the drive name (I named Install OS X El Capitan, in the Terminal I put /In and the tab key, it put the "\" thing on the name

 

[Hasefroch]

In fact it stuck. I had to power off keeping the power botton.

 

[AD1234567890]

Let me try it on my MacBook, because normaly without touching the boot.efi file, it should boot and work at least 2 minutes after the beginning of the installation

 

[Hasefroch]

I will try without replacing the boot.efi, I'm making the USB again but this time I won't replace the boot.efi and instead I put the modified command

Also I will try without the command just osx-patcher 1.2.1, The El Capitan installer from the link provided.

What El Capitan installer you used? I used the OS X Downloader script from the same author as the patcher, it gives me the Install OS X app, not the DMG

 

[Hasefroch]

Now, without replacing the EFI, it booted to the black screen and progress bar! And it's advancing!
