$ codesign - verify - verbose /Applications/Safari.app /Applications/Safari.app: a sealed resource is missing or invalid file added: /Applications/Safari.app/Contents/ASDF/nefariousfile.sh If the app’s contents have been modified (altered files, or unrecognized components added to the app package), then you will see another output, such as the following that indicates a file “nefariousfile.sh” that was added to the program: $ codesign - verify - verbose /Applications/Safari.app /Applications/Safari.app: valid on disk /Applications/Safari.app: satisfies its Designated Requirement When run, you will see output such as the following for Safari that indicates if the app is valid and whether or not its signing requirements have been satisfied:

Drag your desired app to the Terminal window, to enter a full path to it, so it looks like the following :Ĭodesign - verify - verbose /Applications/AppName.app Type the following command, followed by a single space:ģ.If you wish to manually inspect the status of your apps’ signatures, then you can do so using the OS X Terminal:
Mac terminal find file manual#
As such, to check your current installations, manual assessment may be needed to check your current apps.

As such, provided you have GateKeeper at its maximum protection settings you should be able to detect potential problems with new software that you download.ĭo note that while GateKeeper will detect signature issues with programs you are running for the first time, it will not assess changes to those that have previously run. When an app is run on your Mac, OS X’s GateKeeper feature will validate the signature, allowing properly signed packages to run, but requiring explicit execution for others. You can use digital signing to both automatically and manually determine if an app has been compromised, and then further investigate whether to trust the app. While this is difficult to do through official software distribution channels (e.g., the Mac App Store), it can be done through popular alternative approaches like peer-to-peer networking and third-party software distribution Web sites. One potential route by which an attacker can compromise your Mac is to modify a legitimate software package to contain malware.
