Preview of OS X Gen

Hey everyone. So for the last few months Ive been working on a OS X USB creator for Linux because I didnt really like how all the alternatives, like myHack, Unibeast, Kakewalk, etc, would require you to have access to a Mac in order to use them. I also wanted to create a utility that would give the user much more freedom over everything regarding the installation process. Recently Ive been trying to get it stable enough for a public release, and its starting to shape up very well! Really proud of it so far, and I hope some of you look forward to using it. Lastly, heres a few pictures of it :) And the cat picture is just a temporary place holder lol.

This is of the bootloader options screen. Awesome, isnt it?

And heres the SMBIOS selection and customization menu.

Also heres the additional options menu where you can choose from many applications, kexts, and patches that you want to use. Ive spend a lot of time this week trying to achieve maximum compatibility with all the patches.
So far most things have been tested on Leopard 10.5.6, Snow Leopard 10.6.3, Lion 10.7.5, Mountain Lion 10.8.5, and Mavericks 10.9.2. Hows that for compatible! Well thats all for now.

Update: Someone left a comment asking about where the .app or .dmg go, so heres the pictureof the external resources screen. Lets you provide your own disk image, extra folder, applications, kexts, and bootloader :)

Bypassing OS Xs Code Signature Check

I was trying to patch Mavericks OSInstall framework to allow installation on MBR partition schemes, but all of my attempts failed. I noticed that the installers error log reported that it failed to verify the code signature of OSInstall. This never happened to me before with Mountain Lion, so I decided to look into some of the changed in Mavericks. A post by oldnapalm on InsanleyMacs forums confirmed that the installer wont launch OSInstall unless it has been signed to reflect the modifications.

Unfortunately I needed a way to sign this file from Linux, and there are no Linux alternative for Macs codesign program. I decided to compare a signed and unsigned version of the same program to see exactly what codesign was changing. Ill try to make this more interesting by adding in some pictures. Heres two copies of the same program, which are currently unsigned:


So I signed one of them and verified its signature:

Next I compared their differences using the hex editor Hex Fiend.


So theres about 10 locations that differ. Some of these locations contained several bytes, so there was about 40 bytes that differed between them in total. In addition, the signed versions was extended by 9.2 kilobytes of 0x00 characters. I wanted to see what would happen if I changed any arbitrary byte of the signed program and tried to launch it. As expected, the file failed the verification.


So from there I tried changing each altered byte of the signed program back to that of its unsigned versions. Very quickly it stumbled upon the byte that would make the OS think the file wasnt signed.


However, running this file with the 21st byte changed from 0x38 to 0x28 would result in a malformed Mach-o format error when I tried to run the program. Lets exaime these hex values a little bit closer.

 0x28 = 00101000 
 0x38 = 00111000 

The 5th bit is the only thing that changed between these two values, so this bit must correspond to the flag that tells the OS that this application is signed.

So I tried changing a few more bytes, and managed to find the other byte that needed to be changed.


So finally, after changing the 21st byte from 0x38 to 0x28 and the 17th byte from 0x12 to 0x11, I was able to run a modded program which was signed. Lets look at those last hex values:

 0x11 = 00010001 
 0x12 = 00010010 

So the bit that is set in 0x12 but not in 0x11 is the 2nd bit. This must also be related to the the signature check.

After discovering this, I tried applying those same changes to Mavericks OSInstall which had previously failed to launch after being modified. Sure enough, it launched without any problems, and I was able to install Mavericks on my MBR disk. Heres the final pseudo code for how to patch modded, signed applications so that they can run:

 // Clear code signature bits 
 Byte 17 &= 0xFD 
 Byte 21 &= 0xEF 

This works because the OS checks to see if these bits are set in order to determine if the application is signed. So theres no need for it to verify the application before launching it because the OS doesnt think its signed.

Update: I was working with OSInstall again today, March 5th, 2014, and I was able to get the OS to run a modded version of it after only changing byte 17. So changing byte 21 might not be necessary.

Update: Ended up having some problems with developing an MBR patch for OS X 10.10 Yosemite because of the code signature protection. Ended up running a bunch of tests to find a pattern with how bytes 17 and 21 changed when being signed. Things are working much better now :) Heres the final code. Also value is the offset for the start of the current architecture. So it would change for 32bit/64bit/Compatible.

if(buffer[value + 0x10] == 0x24) {
 buffer[value + 0x10] -= 0x01;
 buffer[value + 0x14] >= 0x10 ? buffer[value + 0x14] -= 0x10 : buffer[value + 0x14] += 0xF0;
}
else if(buffer[value + 0x10] > 0x24) {
 buffer[value + 0x10] -= 0x02;
 buffer[value + 0x14] >= 0x20 ? buffer[value + 0x14] -= 0x20 : buffer[value + 0x14] += 0xE0;
} 

Theres probably some binary arithmetic that can simplify this algorithm even further, but Im not very interested in creating one right now.

Update: Someone who did more research than I did left a good comment that explain the flaws in my process. Based on his comment, I guess we can conclude that bits 17 and 21 are not being used as bit field flags to enable the code signature check, however modify them like Ive done will circumvent the security.

Resizing OS X Gen

Hey again! Time for another post where I talk about the progress of OS X Gen. If you dont already know, this program is the worlds first OS X USB creator for Linux. This is actually going to be kind of a long post since I wanted to show off some of its changes and talk about some of the core components of how it works.

Special thanks to sugarface who told me earlier today to continue doing these kind of posts. And thanks to all those whove shown interest in this project so far. Also Ive been collaborating about this program with smx for a few months. Hes certainly helped with getting this all together! Thanks to him too! I showed my blog to someone in real life earlier this week. In total, thats now two people that Ive personally shown all this to. She didnt say much...

Enough about that, time for the good stuff. First thing is the revamped "External Resources" menu. Youll notice that its bigger than before, and has a couple more options. You can now provide a kernel file and select your disk drive as a source for the OS X installer.


Weve also made everything about OS X Gen resizeable now. This is especially useful when selecting from options in the additional options screen. I made sure to expand a lot of the patch options in this picture so you could all see what going to be available ;)


Heres where I wanted to talk a bit about how OS X Gen works. I made his program with modularity and maintainability in mind, and this is how Ive done that. All the options available are created at runtime by reading them in from a file. Fortunately this makes updating and maintaining OS X Gen very simple, and Ive very pleased with how it turned out. To demonstrate this, heres a picture of part of the options file that contains the first few kext patches. I know it looks a little bit complicated, but its all documented pretty well. If you look close enough, youll see that theres ways of making options version specific. This relies on OS X Gens ability to detect the version of OS X that you provide and only display the options that are applicable to it :)


One last thing Ive been working on is getting syntax highlighting to work for the parts of the program that give you the ability to edit text files. Heres a quick example of the "Edit Post-Installation Script" patch. This post-installation script is generated by OS X Gen based on the options youve selected, and it is run by the OS X installer which eliminates the need for any kind of post-installation utilities. I think its looking pretty good so far.
