obviously my 2nd card (which i use on windows for my 2nd monitor, it's a GT710) works out of the box, it has acceleration and is working fine

now i haven't tried removing it yet, it has worked with both GPUs before (before i had to reinstall because of issues) and i can't remember what i did in order for it to work

specs: Xeon X5650@4GHz; Asus P6x58D-E; 16GB RAM; GTX1080 (main 1440p 144hz monitor, g-sync so uses DisplayPort if that's a reason) and GT710 (secondary 1080p 60hz monitor); 10.13.6 17G11023 on a SSD

Clover down below just in case, maybe someone has more knowledge than i do with clover and the web driver so i can get it fixed, thank you in advance

After installing High Sierra

I have this problem
Unsupported CPU - Unsupported PCH

Like in the picture

Is that normal or i should to care about it ?


HP Z420 WORKSTATION
Intel Patsburg C600/X79, Intel Sandy Bridge-EP
QUAD CORE INTEL XEON E5-1620 03.60 GHz
RAM: 22 GB ECC RDDR3
GPU: 2GB NVIDIA GTX 730
 

P.S. i5-3570S, GeForce GTX 650, WD6400AAKS connected SATA2

I have gone suddenly without doing anything in the system. How can I solve that? 

Thanks

In a previous thread, with the help of a DSDT I collected for Motherboard Asus P8H67-M LE, I managed to get all version from Snow Leopard to Sierra working using different

versions of Chameleon.

However Chameleon no longer works for High Sierra & above.

Reluctantly I am now looking into Clover, but am unable to achieve much progress.

Help welcome.

Bootable USB

Terminal:
sudo /Applications/Install\ macOS\ High\ Sierra.app/Contents/Resources/createinstallmedia --volume /Volumes/USB --applicationpath /Applications/Install\ macOS\ high\ Sierra.app --nointeraction &&say All Done

1. Clover_v2.4k_r4359 or latest

2. Install Clover to USB

3. Select Bootloader --> Install boot0af in MBR
4. CloverEFI--> CloverEFI 64-bits SATA
5. Check mark on Drivers64
6. Copy patched APFS.efi, and NTFS.efi to EFI\CLOVER\Drivers64

To patch APFS.efi:  I did not use APFS from Clover.  I got it from 10.13.2 /usr/standalone/i386/

Terminal: 
sudo perl -i -pe 's|\x00\x74\x07\xb8\xff\xff|\x00\x90\x90\xb8\xff\xff|sg' "drag your APFS here"

Edit config.plist using Clover Configuration

on Kernal and Kext Patched add these 3 AppleAHCIPort

Save the file.  Now, you can boot USB with -v

Post-Installation:

1. Clover_v2.4k_r4359 or latest

2. Check mark on Install Clover as ESP

3. Select Bootloader --> Install boot0af in MBR
4. CloverEFI--> CloverEFI 64-bits SATA
5. Check mark on Drivers64
6. Copy patched APFS.efi, and NTFS.efi to EFI\CLOVER\Drivers64

7. Somehow Clover did not generate kexts in Other folder.  So I copy these kexts (see picture).  picture post later

       Note: I use VoodooHDA version 2.8.8.  Latest v2.9.x did not see "green rear plug".  Maybe someone how to patch, if so please post how.  Thanks

8. I would just use config.plist from bootable usb since it already had the patch in it.

Thanks in advance.

acpi_dsdt.aml.bin

first installation, after having done the usb installation through the terminal when I try to finalize the installation on the hard disk I get this error ...this version of mac os x is not supported on this platform.......... I also used the config with the old smbios working but nothing with arg no_compat_check but then I have error prelinked kernel 07, attach my clover with all config test

CLOVERTets.rar

I have my High Sierra up & running, still need to do a few post installation things. Lately I've been getting a boot crash/freeze right on the text ;

MAC Framework successfully initialized

using 16384 buffer headers and 10240 cluster IO buffer headers

Can someone please explain this ??  Or give more information as to where/why it's crashing/freezing here or what it's related to ??

This doesn't happen on every boot which makes it more confusing but enough times to be very annoyed & curious with it.

Please help.

Thanks.

Typical Causes and Solutions:
After searching google for couple of days and with the help of @PMheart I found Alext James (@TheRacerMaster)'s article : http://alextjam.es/debugging-appleacpiplatform/

Because signed char become negative when bigger than 0x7f, Apple rewrote isprint method but seems to forget to cast char to unsigned. Thus, if OemId, Signature、OemId、OemTableId or AslCompilerId in any ACPI table contains a char greater than 0x7f, it will cause a memory overflow.

Most people can solve by:

• dropping MATS/BGRT table( or other table )
• add FixHeaders_20000000 in clover ACPI patch
• Modify MATS/BGRT/other table and change that char to lower than 0x80

But sadly none worked for me

1. I dropped all of my ACPI tables except DSDT and APIC, cuz I cannot boot without these two
2. I searched for APIC and DSDT, none of their OemId, Signature、OemId、OemTableId or AslCompilerId contains char greater than 0x7f

Untypical Situation:
I took a video of my boot process using -verbose, debug=0x100, keepsyms=1 :
see online : https://www.dropbox.com/s/p4eztglltdtqxyb/boot.mp4?dl=0
In the trace, the boot process stuck at isspace other than isprint.
Out to curiosity, I decompiled AppleACPIPlatform and saw isspace looks like this:

                     _isspace:
000000000001f5cf         push       rbp                                         ; CODE XREF=_AcpiUtStrtoul64+71, _AcpiUtStrtoul64+89
000000000001f5d0         mov        rbp, rsp
000000000001f5d3         lea        rax, qword [__ctype]
000000000001f5da         mov        al, byte [rdi+rax]
000000000001f5dd         and        al, 0x20
000000000001f5df         shr        al, 0x5
000000000001f5e2         pop        rbp
000000000001f5e3         ret

And in C language it looks like this:

int _isspace(int arg0) {
    rax = (int)__ctype[arg0];
    return (rax & 0x20) >> 5;
} 

It uses __ctype as an array and rdi, which acts as argument in assembly language, as a pointer to find some char and put it into al. 
I checked the length of __ctype is 256, thus any normal byte, which is 16 bits, won't caus overflow.
However, Apple didn't cast arg0 to unsigned char. Thus, any char that's greater than 0x7f will also cause an overflow.
 
Follw the trace, I found _AcpiUtStrtoul64 the source code is here. Looks like it just uses a loop to judge whether it's a space. No other useful information were found during further dig.
 

New Discovery and Dilemma

Occasionally, i decompiled two programs written to test signed and unsigned char, and were surprised to find,

the only difference between 'cast to unsigned' and 'stay signed' in assembly language is that when delivering argument, unsigned used 'movzx' and singed used 'movsx'.

In assembly language, arguments are delivered by register rdi. So, I think, if I change 'movsx' to 'movzx' then this problem can be solved. Here's where isspace is called inside _AcpiUtStrtoul64:

0000000000001153         mov        qword [r14], 0x0
000000000000115a         movsx      edi, byte [r15]
000000000000115e         test       edi, edi
0000000000001160         je         loc_12b5

0000000000001166         mov        dword [rbp+var_2C], esi
0000000000001169         xor        eax, eax
000000000000116b         call       _isspace
0000000000001170         lea        rbx, qword [r15+1]
0000000000001174         test       eax, eax
0000000000001176         je         loc_118d

                     loc_1178:
0000000000001178         movsx      edi, byte [rbx]                             ; argument #1 for method _isspace, CODE XREF=_AcpiUtStrtoul64+99
000000000000117b         xor        eax, eax
000000000000117d         call       _isspace
0000000000001182         inc        rbx
0000000000001185         test       eax, eax 

Note that edi is the lower 32 bit of rdi .

However, after patching in Clover, it stucks that line 0000000000001178 . And checking the register printed, register edi is empty. That means something's wrong when executing movzx .

If I do not change movsx to movzx, at the panic scene we can see in the above video that register rdi is 0x00000000 ffffffa4 , thus edi is 0xffff ffa4 .

Obviously, the char that caused the problem should be A4. However, I searched APIC but didn't find A4. There is a A4 in DSDT but I have no idea how to modify.

BIOS rom, all of my ACPI tables and modified dsdt/ssdt can be found in attachment.

Need Someone's Help

So, here I'm at a very embarrassed stage don't know where's wrong even what to do next... Maybe something's wrong with one of my ACPI tables? Or with AppleACPIPlatform? Or with AppleSMCRTC?

I'm pretty sure I'm not alone with this question, someone willing to dig into it please check my raw ACPI tables, BIOS ROM, modified DSDT/SSDT and my current EFI folder. Thanks very much.

BIOS ROM:

x7946.rom.zip

Modified DSDT/SSDT, perfect on 10.10 - 10.12.6:

dsdt+ssdt.zip

Original ACPI Tables:

OriginACPI.zip

1. Download macOS 10.13 on my Windows PC (Have no Mac :( ) using gibMacOS (a random utility that download macOS straight from apple and creates a Clover usb)
2. Make a usb flash drive with Clover using the same utility
3. Add FakeSMC
4. Set BIOS to AHCI and UEFI
5. Load it! <---- This is where things got rough

First I got a prohibited sign, looking at the config file this was because the SMBIOS settings were set to emulate a iMac G5 bios. After editing that, the installer continued loading until the +++++++ and then it just restarted without error.

Anybody got an idea why it might restart?

System Specs:

Intel Core i7 M640 @ 2.80Ghz
120GB Kingston SSD
NVIDIA NVS 3100M
1600x900 Display
8GB of RAM

i have an asus x550l i've try many ways different kexts, differents installation methods guides and nothing 

this is are the specs of my laptop. Please if you can help me make the correct installation usb would be great. oh i forgott to mention that the only USB 2.0 y have is broken only have left 2 3.0 USB

My setup is:
Asus ROG Strix B250F Motherboard

G3930 Celeron Kaby Lake

4 GB DDR4 ADATA

ASUS ROG GTX 1070 8 GB

SSD 120 GB Kingston A400

I made the setup using a macbook air and downloaded the high sierra from the store. Used disk utility to format the usb drive and then copied the high sierra using the command line. After finishing I installed clover on the EFI partition.

Made the default BIOS setup like load optimzied default, enabled virtualisation, etc.

The usb boots but the screen doesnt have the install mac os high sierra option, only the UEFI SHELL 64, Clover Boot options, Options, About clover,  Restart and Exit Clover.

Anybody can help me with this monster of a computer (in a bad way)?

Thanks!

I had a look at all the forum sections & wasn't sure where to post this as the guide I'm following is Closed so I couldn't post my questions there.

I am following the great KGP's guide here :: https://www.insanelymac.com/forum/topic/331703-how-to-build-your-own-mac-pro-based-on-broadwell-eep-haswell-eep-and-x99-successful-buildextended-guide/?tab=comments#comment-2570747

I was originally looking at another one of his guides but this one seems a bit newer/updated.

In section "B1.) ASUS Mainboard BIOS Patching"

I have done the instructions & got the return messages in terminal just as the guide shows, & successfully made a patched BIOS file which I renamed according to my motherboard model & used the patched BIOS file to flash my motherboard BIOS using BIOS Flashback just as the guide shows. My original BIOS  I was on was 1802 & my new patched BIOS is 2101.

Can someone PLEASE tell me a way to confirm that I have successfully unlocked the MSR 0xE2 Register ?? 

KGP's first guide I was reading into involved UBU & MMtool to unlock/patch my BIOS CPU Microcodes but I think that method is outdated now??  As this guide I posted the link to doesn't use UBU & MMtool to patch/unlock but instead uses CodeRush's UEFI patch to unlock MSR 0xE2 Register. 

Thanx for your time,

Ash.

- you will need at least 8GB USD flash drive

Step 1

Download 10.13 from App Store into applications folder 

Step 2

Download Disk Maker X

Step 3

Create 10.13 installer USB using Disk Maker X, follow instructions - this process will take a while (15mins or more)

Step 4

After the the installer USB has been created, install Clover. 

Customize

 - Install Clover in the ESP

 - Bootloader => Install boot0af in MBR

 - CloverEFI 64-bits SATA

 - Themes => (your choice)

Step 5

Add required kext to EFI/CLOVER/kexts/others (here is the kext that I used HighSierraKexts.zip) 

Step 6

Add apfs.efi  to EFI/CLOVER/drivers64UEFI

--------from here you can boot to the USB install and follow instructions,  your system will reboot always remember to boot to the USB and then select the correct driver. After booting to your new OS, install clover to the main driver using the same procedure as above.

Please note that I did not need kext for LAN and Audio because I have compatible PCIe cards. The system is stable.

Good Luck!

===

Update:

The system now reads correct memory. I followed the Motherboard installation guide on page 21(Installing DIMMs). The last option for Six DIMMs: If using more than 4 DIMMs, use: DIMM slots 2, 1, 4, and 3 then proceed to occupy the following DIMM slots in this order: 6 and 5

I've also noticed that if the computer goes to sleep it completely shuts down instead.

I need to know if we are stuck with max 15 ports. 

My mobo has 13 physical ports. 6 of those are USB 3.0. Since USB 3.0 reads 2.0 I get 12 possibilities.   Ex: SSP1 - HS01,  SSP2 - HS02.

See them all if I enable the "disable port limit". 

Did the SSDT thing. 

Disable the "disable port limit" kext patch and I'm down to 15 ports. 

Also in System information all ports show up under USB 3.0 Bus.  Cosmetic? Can it be fixed? 

Thank you.

When I open a pdf or image file, a color overlay is created on the images and files as below. It can be temporarily resolved by enlarging or shrinking the image, but re-creating it. What is the problem and how should I fix it. The specifications of my system are as follows:

System: Dell Optiplex 780

CPU: INTEL Core2 Dual Q9550

GPU: ATI Radeon HD 5040 1024 MB

OS: MacOs High Sierra 10.13.6

The graphics is not enabled, i’ve found various topic for resolve that but no one works.

Ive tried to changed my config.plist, install FakePCIID, Lilu, WEG, and patch my DSDT but no one works.

I need help, thanks you very much.

It is HS Recovery image - FireWolf OS X PE 9
