DSDT editor and patcher

Q: What is a Hackintosh?

A non-Apple computer configured to run macOS using compatible PC hardware combined with a custom bootloader and configuration files to emulate a real Mac environment.

Q: Is building a Hackintosh legal?

Installing macOS on non-Apple hardware violates Apple’s End User License Agreement (EULA). It is generally not illegal for personal experimentation but not permitted for commercial use.

Q: What hardware is best for a Hackintosh?

The best hardware closely matches real Apple systems, with Intel CPUs (6th Gen to Core Ultra), AMD Radeon GPUs, compatible chipsets, and Intel-based Wi-Fi cards offering higher success rates.

Q: Can I build a Hackintosh with an AMD CPU?

Yes, macOS can run on AMD Ryzen CPUs using kernel patches, but Intel CPUs provide better native compatibility.

Q: What is OpenCore?

OpenCore is a modern Hackintosh bootloader that provides near-native macOS behavior and is the recommended bootloader for new installations.

Q: Is Clover still supported?

Yes, Clover is still supported but less recommended compared to OpenCore for modern systems.

Q: Which macOS versions support Hackintosh?

Hackintosh systems support macOS versions from Leopard up to recent releases, depending on hardware compatibility.

Q: Do NVIDIA graphics cards work on Hackintosh?

Only older NVIDIA GPUs work on older macOS versions; modern NVIDIA GPUs are incompatible with current macOS releases due to lack of driver support.

Q: What is an EFI folder?

The EFI folder contains the bootloader, drivers, kexts, and configuration files required to boot macOS on a Hackintosh.

Q: What are kexts?

Kexts (kernel extensions) are drivers that enable hardware functionality such as audio, Ethernet, USB, and graphics.

Updated: MaciASL

Editor developed by phpdev32, compatible with DSDT Editor patches.

el coniglio released this DSDT editor with automated patching capabilities

The main editor windows allows the user to open a DSL file or extract the DSDT from IOReg. It has some useful resources, like syntax highlighting, navigation tree and some options that came with the text editor component it uses, like regex matching, auto completion, jump to pair, etc.

The patcher window parses a script-like language representing the patches. The user can preview the modifications before applying them. This "language" allows us to write dynamic patches that can be applied in various situations. More specific commands can be written as they become necessary.

For now these are the implemented commands (which can be stacked separated by ";")

Quote

syntax:

into [ ... ] begin [action_argument] end

(will be applied to the first occurrence)

into_all [ ... ] begin [action_argument] end

(will be applied to all occurrences)

where

type: DefinitionBlock, Scope, Method, Device, Processor, ThermalZone, All

property:

label -- first argument for the constructor of selected type

name_adr -- Name (_ADR) value

name_hid -- Name (_HID) value

code_regex -- regular expression to match the code of the selected type (not other types inside of it)

code_regex_not -- regular expression NOT to match the code of the selected type (not other types inside of it)

parent_label -- parent label

parent_type -- parent type

parent_adr -- parent _ADR value

parent_hid -- parent _HID value

action:

insert -- inserts the provided code to the type

set_label -- sets the label

replace_matched -- replaces the matched code for the property with the provided code. Regex groups are inserted with %1, %2, ... up to %9

replaceall_matched -- same as replace_matched but will affect all matches

remove_matched -- removes the matched code

removeall_matched -- removes all the ocurrencies of the matched code

remove_entry -- removes the entry and all children nodes

replace_content -- replaces the content of the object (everything inside its main brackets)

store_%8 -- stores the matched group 1 into %8

store_%9 -- stores the matched group 1 into %9

note: replacer will always consider the last provided value

Changes in latest release:

fixed bug which caused data loss if number of open and close brackets don't match
fixed compile window to work with new IASL versions
updated IASL to 20120420

Hello oldnapalm...

There is a DSDT editor and patcher that can be run in Windows rite... So I ran it in Windows, extract DSDT, I get dsdt.aml and dsdt.dsl... My question is can this dsdt.aml and dsdt.dsl be used in the OSX that I've installed? I mean it will reflect the same setting whether it is in Windows or in OSX rite...

oldnapalm · September 25, 2011

If you extract DSDT in Windows and copy it to Mac OS without patching, it will make no difference. Windows uses DSDT from BIOS, untouched. It would be the same as leaving Mac OS (Chameleon) without a dsdt.aml file, it will get the original from BIOS.

hackerz · September 27, 2011

Ooo... I see ... So dsdt.aml is mainly needed by Chameleon and to act as it is a BIOS itself... Am I rite? How about Chimera? Is it the same if I use Chimera instead of Chameleon? Or is it the same bootloader thingy? Ehehehehe...

Another thing I want to ask... What kind of patching do you usually do to the dsdt.aml? What sort of data that you add/patch to dsdt.aml? Sorry for asking this question as I have no clue about dsdt.aml and most of the thing that I must have to run OSX on my HP Envy 17 (with all hardware functioning as in Windows )

oldnapalm · September 27, 2011

Actually the boot loader (no matter if it's Chameleon or Chimera) loads the patched DSDT from file (dsdt.aml) and passes it to the OS, instead of passing the original DSDT from BIOS.

The needed patches depends on hardware

hackerz · October 2, 2011

Hello oldnapalm...

I've gone through the link you've given... But from what I've seen, the lists seem have nothing to do with my hardware... Could you recommend me which patch/patches I should apply to my dsdt? (or don't need to... Ehehehe)

I have HP Envy 17 laptop...

oldnapalm · October 2, 2011

I can't tell what patches you need without installing Mac OS and testing first.

Probably some of these patches will be usefull for you

Also, like scorpioserve, you will probably need the lapic kernel (Taptun).

hackerz · October 4, 2011

Thank you for your excellent link... This is absolutely like what I said before... I've got basically Intel Core i7 but the thing that I should have a look at is Core i Nehalem rite... Without your guide, I wouldn't bother on that thing

Anyway, what do you mean by testing first? Do you have any software for that? Or something...? And I would like also to ask you about the lapic kernel (Taptun)... What is the function of this kernel compared to the original Mac OS kernel (I believed it is called mach_kernel rite...)?

Thank you for your time in answering my noob question... You are the best oldnapalm... Ehehehe

oldnapalm · October 5, 2011

By "testing first" I mean install Mac OS, check what issues you have and if they are fixable via DSDT.

The vanilla kernel doesn't work on many Core i HP laptops, you have to use "cpus=1" or you get kernel panic (local apic error). The Taptun kernel is patched to fix that problem.

hackerz · October 5, 2011

Oo ok... Well, actually this is my situation...

I've installed Lion on my laptop... I've used rBoot from tonycrap and the installer is located in an external HDD... I've used cpus=1 busratio=12 as the kernel flags... So the default PCIRootUID should be 0 rite... After a few minutes passing the apple logo, my screen became like the picture below :

When I include PCIRootUID=1 in the kernel flag, after a few minutes passing the apple logo, my laptop screen becomes blank and I have to use external screen to proceed with the installation and so on until I get to the desktop... This situation also happens every time I boot my laptop into Mac OS... In the end, I have to use external screen (connecting monitor using VGA or connecting my TV through HDMI port) to see my desktop... That is one thing that puzzles me coz when I installed and run SL 10.6.3, I've no problem at all to get the display on my laptop screen (using PCIRootUID=1 or else the screen will becomes like the image above)... But after I combo update Snow Leopard to 10.6.8, the same situation occured...

So what do you think oldnapalm? Do you have any idea to get around this problem? Or any suggestion/solution? Ehehehe

oldnapalm · October 5, 2011

I think this has nothing to do with DSDT, it's a video problem, look for "GraphicsEnabler + AtiConfig". If it doesn't work, look for "forced EDID".

hackerz · October 6, 2011

Yupes... Just read about that somewhere on the net but still struggling on doing what they say... Well, I'll certainly will look on that part... Thanx oldnapalm for your superb help and guide and explaination on this thing... Sorry for taking your time on this matter and I'm sure I'll be bothering you more often after this... Ehehehe

Hello,

Sorry for my bad english, i'm from Romania and i've used your DSDT editor and patcher to generate the dsdt for my machine and ad a patch for my video chipset 4500MHD, but i get the a KP on load. I have loaded a picture with the KP, can you help me please and try to fix my dsdt??

dsdt.aml.zip

KP1-DSDT.jpg.zip

Thank you for your time!

Cassio · October 21, 2011

Invalid File ID

It was deleted, probably because it doesn't work. GMA 4500 isn't compatible with Mac OS, it can't be fixed with a DSDT patch, you need kexts which don't exist.

duo · October 21, 2011

The ideea is to force load the kext with the help pf the dsdt. But I can't do that because i get the KP I have attached. Can you help please and corect the dsdt?

Thank you!

Cassio · October 21, 2011

You got KP because you saved a DSL file with .aml extension. You have to compile it first, then save as AML.

The patch has wrong chars in lines 20-21, that's why IASL fails with "Non-ascii input file"

GMA4500.txt.zip

duo · October 22, 2011

Thank you for your response, unfortunately even if I only aply the DTGP patch, and after that i compile, i get the same KP. At the moment i'm more interested in making the dsdt work. I've atached the dsdt.aml. Can you please take a look??

dsdt.aml.zip

Also my specs are:

Lenovo Thinkpad X200, Model No: 7459-3T5, 12.1" LCD Display, Intel 4500MHD Chipset

Processor: Intel Core 2 Duo T9550, 2.67GHz, 4GB RAM DDR3,

320GB WD Hard Drive, Conexat Cx20561 Audio Controller,

Intel 4500MHD Video Chipet(Device ID: 0x2a42, Revision ID: 0x0007)

Atheros AR5008X Xtreme N Wireless Card.

Dual Boot System: OSX SL -> Windows 7

Cassio · October 22, 2011

Again you saved a DSL file with .aml extension. You have to compile it first, then save as AML. Watch the video in the first post.

duo · October 22, 2011

Sorry about that, i've attached the wrong dsdt. I have corected the 4500 patch but the dsdt still doesn't load the kext, can you please explain why or can you edit for me the patch in loading the kext from dsdt???Thank's!

dsdt.aml.zip

Cassio · October 23, 2011

You applied only DTGP. You need both DTGP and the one I attached.
