1. Sure go ahead.
2. Fully disabling code sign checking needs a kernel patch as well as some other which I haven't found yet. Need time...

Thanks!!!

Cool tool.

I study the code, it removed sign related command and data from mach-o. 

I'm wondering why the binary can't be signed with another certification now?

Look forward for your update.

I'm still checking why.
It just doesn't want to resign afterwards.
Probably needs to be realigned and sizes adjusted.

Hi Andy,

 

Probably a silly question but can this be run on a intel i7 based mac? if not what needs to be changed to enable it to run?

 

Thanks for the help and sorry if its a dumb Question but I've been playing around with it and havent been able to get it to run as im on a i7 mac and keep getting this error:

 

d: warning: ignoring file Makefile, file was built for unsupported file format ( 0x43 0x43 0x3D 0x67 0x63 0x63 0x0A 0x43 0x46 0x4C 0x41 0x47 0x53 0x3D 0x2D 0x61 ) which is not the architecture being linked (x86_64): Makefile

Undefined symbols for architecture x86_64:

ld: symbol(s) not found for architecture x86_64

clang: error: linker command failed with exit code 1 (use -v to see invocation)
