The /usr/bin/codesign file on our server was removed. It is running version OS version 10.9. Does anyone know where I can download the codesign file for OSX 10.9? Or can anyone pull it off their computers for me?

  • Do you have Xcode 5.x with the command line tools installed ?? - I have the codesign tool with my Mavericks. Commented Jan 8, 2014 at 22:02

1 Answer 1


From OS X 10.9.1: /usr/bin/codesign

Alternatively, grab it from your Recovery HD:

diskutil mount Recovery\ HD
hdiutil mount /Volumes/Recovery\ HD/com.apple.recovery.boot/BaseSystem.dmg
sudo cp /Volumes/OS\ X\ Base\ System/usr/bin/codesign /usr/bin/codesign

I recommend you do a permissions repair after copying.

    We might need a canonical, where can I get file X that I just removed from my Mac....

    @bmike I've written a canonical Q&A for that (still think the question could be improved a bit maybe): apple.stackexchange.com/questions/116611/…

    I like how the canonical question is working out. Hit me up in Ask Different Chat this weekend. It might be nice to pick another sort of canonical question or two to try asking / answering. Perhaps a fun one like Clash of Clans / Game Center and another more serious one.
