How to run Keygen/Patch on OS X Yosemite

Hi guys,
I have received many mails with content 'I can't run Keygen/Patch on OS X Yosemite'
Today, I will guide you to fix it. Hope it helps you !

When you run Keygen or Patch, you get message :

1. Download Codesign Unix from 10.9.4 and put it in desktop

Mediafire
Mega.co.nz

2. Open Finder, press Command+Shift+G and type /usr/bin/codesign

3. Rename 'codesign' -> 'codesignbackup'

4. Drag 'codesign' from desktop into this folder (type password confirm)

5. Done ! Run Keygen/Patch to check !
