1。 Download the attachment CDSN 1094 from the Internet, which is a codesign file copied from the 10.9.4 system.
2。 Select a menu from the Finder, and then select a folder. Enter the path in the input box: /usr/bin/
3。 Rename the original codesign to codesign 1095(3 (you need to enter the permission password in steps 3 and 4).
4。 Copy the codesign in the attachment to the /usr/bin/ directory.
So you can open the patch class to crack the file.
Ps: If you are worried about using the old signature rules, you need to use Apple's new signature rules. Just delete the copied codesign file, and then change the original renamed codesign 1095 back to codesign.
