macosxbootloader's Introduction

Introduction

This Github project is a new and updated branch of the Yosemite tree and is now targetted at OS X 10.11 El Capitan.

Goals

This project aims to add support for El Capitan (OS X 10.11) for unsupported Mac hardware with a 32-bit only EFI implementation. Like for example the first and second generation Mac Pro models. Though it should work well with any other model with a 32-bit EFI implementation.

Current State

The current state of this project is: Phase 1, 2 and 3 completed (OS X 10.11 El Capitan is now fully supported).

Note: For more information about the development phases, please visit the TODO list.

Download

Prebuilt copies of boot.efi can be downloaded from the project download page.

Compilation

Don't want a prebuilt copy of boot.efi then compile the source code yourself, with either Microsoft Visual Studio 2013 or 2015. The latter requires you to update the solution files, but that should be done automatically in the MS Visual Studio IDE.

Note: See also Compiling-Instructions

Thanks To

This project would not have been possible without the help of Peter Holbrook and Mike Boss. Peter did all compiling and Mike ran dozens of test builds that Peter pushed out over at forums.macrumors.com Awesome work guys. Job well done!

macosxbootloader's Issues

what about imac 4,1 and 5,1 ?

I read in the readme that this injects a fake board id for macpro etc, but what about imac 4,1 and 5,1 ?

After I download and installed the new boot.efi, it keeps rebooting

I have a MAC PRO 1,1 with OSX 10.6.8. After I download and installed the new boot.efi, it keeps rebooting. The Apple boot screen changed from white to black background. Please advise how to fix it. Thanks

Update to 10.11.3 causing problems

Used the boot.efi with prepackaged 10.11 installer, worked fine on MacPro 1,1. System updated to 10.11.3 and as expected boot failed. tried fresh install with 10.11 and now hangs just after boot, never finishing completely. Any thoughts or expirences?

All patched machines end up with same HW UUID?

I have patched two MP1,1 machines, and both end up with the same HW UUID when running El Capitan. Other people apparently also end up with this same UUID. Not a problem... unless you're using Time Machine! The two machines think they're using the same data set, and fight over it, making a mess. Is there a way to get one of them to use something else for a UUID?

Googling the particular Hardware UUID, "2B12FE1B-1090-593B-B740-2E45F371D1E4", shows that other people running this patched boot.efi have it too. For sure one of my machines started life as a 1,1 and I've upgraded its firmware and CPU's to a 2,1 8x3GHz state. The other one says it's a 2,1 and is also is 8x3GHz, but I don't know if it was built that way or was also patched up as I did.

Mac Mini 2 stops with grey logo

When i boot my mac mini 2 with the boot.efi it stops on the grey boot screen.

Whats the issue?

How can I boot El Capitan boot.efi into a 32bit-EFI 2007 Macbook 2,1? Just modifying PlatformExpert.cpp?

UPDATED QUESTION: Can I boot with my Macbook 2,1 changing a line of code, for example,
line 270 of PlatformExpert.cpp, and recompiling?

from
else if (memcmp((CHAR8 *)boardId, (CHAR8 *)"Mac-F42187C8", 12) == 0)// MacBookPro2,2
to
else if (memcmp((CHAR8 *)boardId, (CHAR8 *)"Mac-F4208CAA", 12) == 0)// MacBook2,1

Or do I need to do something else?

ORIGINAL POST:
Hello, I see it works wih MBPs and MPs. What about MBs?

I've done this link to macrumors:
"Technically it's possible -- clone the OSX 10.11 Partition with CCC from the MBP3,1 to the MB2,1. Enable the Remote Desktop before since USB isn't working on the MB2,1 under OSX 10.11 and therefore no Input Devices are available. Replace the Boot.efi in /System/Library/CoreServices and /usr/standalone/i386 with the SIP-off version from Post #351 (Build 2). Reboot the MB2,1 and look if OSX 10.11 works or not. To get USB working, copy the Beta-USB-Kexts (provided by TMRJIJ - OS X Hackers) into /System/Library/Extensions/ , replace the current Kexts."

It nearly boots, USBs are working, but I can only boot in single-user-mode. In safe mode or normal boot I get kernel panics. In safe mode, it seems that will boot, but after this screen and after entering the pasword it reboots.

I wonder if this is related to boot.efi or not. Can you tell me something?

Running 10.10.1 with nVidia Web drivers (343.02.01f01) and an old XFX GTX280.

As soon as I swap out the GTX280 for a GTX750, I get blank display after boot and ScreenSharing from my MBAir shows a virtualised display.

If I remove the SSD from the MacPro1,1 undo/revert to Apple's bootloader and install it into a 2008 MacPro 3,1 along with the GTX750 GPU, everything works fine...

Please see http://forum.netkas.org/index.php/topic,8583.0.html for all my attempts/efforts to get it working in the past.

Random Kernel Panics

Hi,

I do not if this is related to the boot loader, but my machine keeps crashing on any OS X Version higher than Lion. It is very stable an does not crash in Lion, but in Mavericks and Yosemite. It is very annoying...The Mac Pro crashes very often at startup or after sleeping.
Here two shots of the panics at startup:

While crashing sometimes a red led on the logic board (or two) is lightening:
https://www.dropbox.com/s/zk1lzfxjmyhyb4i/DSC_0040.JPG?dl=0
They indicate a hardware crash of the cpu?

First I thought that it is a hardware issue. But I ran the machine with less ram and different graphics card and it still keeps crashing. It was even checked by the dealer which sold me the mac. It seems that the machine does not crash with lower OS X versions (can not get it to freeze).
There are no logs about the panics which seems strange to me.
Is there any possibility to identify the origin of the problem? The mac keeps crashing on a clean install.

Here are the specs of the machine, thanks a lot!

Mac not going to sleep, Mouse stuttering

When sending the MacPro1,1 on 10.11.3 to sleep nothing happens except the mouse starting to stutter. It seems that some sleep mode is activated but not the right one. Is this a known issue?

No Keyboard or Mouse for Login Screen

i installed the new boot.efi files on a drive with 10.11.6 and then installed the drive in my 2006, macbook pro. it booted very very slowly and then i got the coveted login screen. oh, but wait.... my keyboard and mouse aren't recognized so i can't type my password in the field. it then auto restarted and would continue this loop....

How to download and install

Hello Piker-Alpha
I have a two question for you:
1.How to download macosxbootloader
2.How to install same boot loader?
Thanks in advanced!!!!!

ACPI Patcher

Hi and thanks for all the fish!

I get a Mac Pro 1,1 last week.

After understanding this machine and wondering it has only 2 (!) powerstep-modi (2GHz and 2,6GHz), it would be great, if custom DSDTs and others could be used.

I would like to test, if we could learn this machines to have more speedsteps and consuming less energy.

Have a nice day!

Question : bypass EFILoginUI

It's not issue, just a question.

Can this bootloader be used on 64 bits ?
Does your bootloader bypass the EFILoginUI on 64 bit machine ?

Thanks.

At first it works perfectly fine but after a while the card is not more recognised.

Message & FaceTime not working

FaceTime and message seem to fail authentication with apple servers. I may call and play dumb to see if they can whitelist my serial. It is a genuine Apple Mac after all.

Network and Bluetooth Problems

Hello volks and thank you a lot for this awesome project!

I've installed OS X 11 with boot.efi v3.1 on a Mac:
MacPro1,1 · 2x2,66 GHz · 7 GB RAM · BootROM MP11.005C.B08

First of all: It's very slow. I didn't test it with OS X 10 but with OS X 9.5 this Mac is much faster respectively it runs very good with OS X 9.5

Bugs with OS X 11:

Bluetooth connection to Keyboard (Model 2007) failed
Internal Network connection and VNC not possible

OS X El Capitan

i have mac pro 2.1 and i install OS X El Capitan 10.11.6
graphic card nvidia quardo fx 4500 not work

32 bits boot.efi doesn't work with OS X El Capitan Security Update 2016-001

Unfortunately, the 32 bits boot.efi doesn't work with the Security Update 2016-001 for OS X El Capitan. The boot process throws error, and the system reboot constantly.

I've checked bothboot.efi files in /usr/standalone/i386 and /System/Library/CoreServices, and PlatformSupport.plist file as well: no one has been touched or updated by this patch. The problem seems to rely on some new kernel incompatibility with the 32 bits boot.efi.

I'm sorry, I don't have any textual log or error output. The only thing I can join to this report is a boot screen photo with the crash.

The only solution was to restore my full system using Time Machine...

system_profiler SPPCIDataType crashes

I am using this boot loader on a MacPro1,1 and when /usr/sbin/system_profiler tries to list the SPPCIDataType data type, the program crashes. No idea if that is related to the bootloader or not ...

Apple logo or loading bar doesn't immediately show up!

Mac OS X El Capitan USB Ports Not Working!

Hello, i've successfully installed Mac OS X El Capitan on my Mac Pro 1,1. It booted up normally(also, i have a radeon hd 5770 not stock card.) but the USB ports aren't responding, i tried switching my keyboard and mouse to different ports, nothing. I tried to plug in a USB flash drive, nothing. Please Help!

Mac Pro 1,1 and El Cap Security update 2016-002

Has anyone experienced a problem with the 2016-002 update of El Capitan? For me, after update, the boot process starts normally, but with the progress bar is halfway through, the monitor goes off, occasionally flashing...showing that the progress bar is not moving. It never seems to finish the boot.

My Mac Pro still boots from another disk with the previous OS. Running fsck verifies that the disk is fine.

Should I retry the install...or is it s problem with the boot.efi file?

bug in _aullshr

the function "_aullshr" is totally wrong in src/boot/x86/CompilerX86.cpp

correct implement is

extern "C" int __declspec(naked) _aullshr()
{
    __asm
    {
        cmp         cl, 64
        jae         RETZERO

        cmp         cl, 32
        jae         MORE32
        shrd        eax, edx, cl
        shr         edx, cl
        ret

    MORE32:
        mov         eax, edx
        xor         edx, edx
        and         cl, 31
        shr         eax, cl
        ret

    RETZERO:
        xor         eax, eax
        xor         edx, edx
        ret
    }
}

Can't Delete boot.efi to replace it

After Security Update 2018-001, MacPro 1,1 no longer boot

My MacPro 1,1 using Piker boot.efi worked fine until the last "Security Update 2018-001".

Now, the machine starts booting then loop back to chime ...

In verbose mode, no "interesting" (for debug) message seems to be shown.

Any idea ?

boot.sln does not generate 64-bit boot.efi version

With any compiler Configuration (Release, Release(Black), Release(Grey) on x64 Platform and Build boot.sln does not generate .efi file.
.lib file has been generated.

I've tried both VS 2013 and VS 2015.

The Gestalt selector gestaltSystemVersion is returning 10.9.6 instead of 10.11.6

Hi there, I followed all the steps on how to make my old MacPro 1,1 run on El Capitan. And it works! However, when I try to install Adobe Acrobat Pro it gives this in Console: 21/11/17 15:28:12,143 AdobeAcrobat[5119]: WARNING: The Gestalt selector gestaltSystemVersion is returning 10.9.6 instead of 10.11.6. This is not a bug in Gestalt -- it is a documented limitation. Use NSProcessInfo's operatingSystemVersion property to get correct system version number.
Call location:

Acrobat runs sorta, but a lot of functionality is lost. I cannot drag documents into the icon, they just won't open. And also I cannot use Find.

Can anyone help me get the version: 10.11.6 right?

Thanks, Newbie Bertus

Piker Alpha Support (upgrading Mac OS X 10.7 to Mac OS X > 10.9)

Can this work with 10.9 Mavericks or is it tied more strictly to OS 10.11 El Capitan?
Will UEFI swap disable OS X from working on previous versions? I.E. will OS X 10.7 now not work with Piker UEFI update?
Can 10.7 be dual booted with 10.8+?
X 1900XT graphics cards will they be able to run OS X 10.11 El Capitan or not?
