Take the 2-minute tour ×  I have a .bundle that is digitally
signed. I can verify this by opening the bundle by selecting
"Show Package Contents" and indeed there is a _CodeSignature
directory underneath the bundle.  However, I am trying to figure
out who is the signer of the bundle. Is there any way with
Xcode, or any other tool, command line or otherwise, to view the
certificate that was used to sign the bundle?  share|improve

have the optional command line tools that XCode will install for
you, codesign is the tool of choice.  Using the Terminal app:  $
codesign --display -vv /Applications/GarageBand.app/
