hex - Comparing two mach-o files

Question

I have two mach-o files and i need to find the difference(hexadecimal differed values) in them. is there any tool available for doing this.

i tried using "DiffMerge" but it doesn't have the supported encoding format it seems.

Answer 1

どうですか：

hexdump binary1 > dump1.txt
hexdump binary2 > dump2.txt
diff dump1.txt dump2.txt

これにより、diffファイルが作成され、hexfiendの最初の列のオフセットを使用したり、エディターの選択でさらに調査したりすることができます。
