MAC Create certificate (to create GDB certificate for example)

Open/applications/utilities/keychain\ access.app/

Open Keychain Access

Keep going.

The creation is complete.

Now the We have a certificate and we need to use it to sign GDB. First, we ' ll restart the taskgatedprocess to make sure it picks up the new certificate. Quit Keychain Access (you must quit Keychain access!) and return to the Terminal for these final commands.

Find the taskgated process.

$ PS - e | grep taskgated

The first number in the above output is the PID. Use this to kill the process (it'll immediately restart itself).

Now the can finally code sign GDB.

# Homebrew version
$ codesign -S Gdb-cert $(which gdb) 　　

Now you should is all set! The OS X Keychain may ask for your password the first time you attempt to debug a program, but it should work!
