Decompkernelcache 2.0 - kernel cache extraction tool

1 post in this topic

Recommended Posts

I updated the sources of the decompkernelcache tool.

Now it can do the following things with the prelinked kernel and its data:

- Uncompress prelinked kernel (package with drivers inside)

- Extract kernel (repackage possible with kextcache, kernel only)

- Extract kexts (including original folder source directory)

- List kexts

- Extract combined Info.plist resource

 

It can do this with prelinked kernel caches compressed with LZSS and LZVN.

It can also extract already decompressed prelinked kernel cache binaries.

It is also possible to specify an architecture to extract (in case of a multi architecture prelinked kernel cache).

 

It works with any version of the OS X kernel cache (It works for 32 and 64 bit, extracting all).

 

I tested it on a prelinked kernel of iOS also, it was able to do this to an iPhone 4S prelinked kernel too. (32-bit ARM)

It works on Mac OS X prelinked kernel data with any version or architecture (32/64-bit works, can extract Big Endian data so if you manage to have a PowerPC prelinked kernel it can handle them too).

It should be able to handle any architecture and any Darwin deployment target.

So if you have a decrypted prelinked kernel of iOS, Mac OS X, Apple TV (both Intel and ARM), Watch OS and any other like the HomePod OS you can use this tool on them too.

 

Enjoy ;)

      Good morning, everyone, I'm sorry if I was wrong in choosing the topic but I need help.
      I have found it extremely difficult to mount a Hackintosh in my acer.
      Setup;
      I5 2430m 2.4 6GB RAM
      Mobo P5we0 - Intel intel Graphics 3000
      At the moment I have not found out what my audio codecs are.
      but I'll leave the link on the motherboard.
      however, my real problem is several.
      I have already used the itakos image, I have already used several images that could be installed normally and that after installing the image I do not have internet via cable or wireless.
      And another, I already looked in other forums and I know that I will be called a donkey in the logical question but I have not been able to install the [url="http://www.insanelymac.com/forum/topic/279450-why-insanelymac-does-not-support-tonymacx86/"]#####[/url] or clover to start from the Hard Disk, so I do not know what to do.At the moment I still do not know if there has already been someone who has already installed the High Sierra or just the Sierra in this notebook model and obtained permanent success.
      If anyone can help me, I'll be grateful.
      Installations without success, but with the system already installed in ACER;
      SIERRA
      HIGH SIERRA
      MOJAVE
      All with the same symptom. Starting only by the bootable USB stick and without internet connection via cable and wireless.
      Appreciate ! Acer 5750 Official Page

      Hi,
      do you know where someone could start getting involved in development for Hackintosh / IOS (jailbreaks etc.) development? I am searching for information about the Kernel development rather than developing apps. 
      I recently finished my bachelor of engineering in electric engineering but the computer science always interested me more. We are being tought about some principles of a operation systems and writing code in c..
       
       
      Until know I found the apple developer website, and the books from Jonathan Levin (but they are some kind of expensive for my current situation as a student).
      I also think that it would be useful to get started with the structure of the linux kernel.
      Do you have more sources I could learn more? How did you become what you are know in the hackintosh community? 
      Google is not very helpful "Hackintosh development" only brings up how to develop apps with an hackintosh...
       
      I posted it in AMD because I am especially interested in the kernel manipulation to get the XNU Kernel working under AMD. If this is the wrong corner, please move it in the right one. 
      Thank you.
       
      EDIT
      And for sure other sources are the wikis of insanelymac and the other hackintosh websites!

      So. My laptop: Asus k55a I installed Mac OS X on the pendrive and now when I turn on the laptop and clicking esc bios it does not detect it. And now I have a question for you what settings I should set up to make everything good

      Good afternoon. I would like to ask about my iron. 
      Will Mac OS X go to it? amd athlon(tm) ii x2 245 Nvidia GeForce GT 630  
      If so, can you give a link to the iso file?
      Thx ♥

      We are very close to WWDC 18, so the expeculations are very high. Look at this graphics:

      One of the big expectations for macOS is be a cross-platform system, to help developers bring their iOS apps to the Mac platform.
      Let's see...
