Mach-O Unsign
Package for removing Mach-O code signatures
Overview
A broken code signature is often worse than no signature, so it can be desirable to remove a signature.
This package can remove code signatures from Mach-O binaries.
Both thin and fat binaries are supported.
Usage
Just pass an ArrayBuffer or an object that is a view of an ArrayBuffer to the unsign function.
If the binary is signed, an unsigned binary in a new ArrayBuffer will be returned.
If the binary has no signatures, null will be returned.
import fs from 'fs';
import {unsign} from 'macho-unsign';
const unsigned = unsign(fs.readFileSync('macho-binary'));
if (unsigned) {
console.log('Signature Removed', unsigned);
fs.writeFileSync('macho-binary-unsigned', Buffer.from(unsigned));
} else {
console.log('Not signed');
