Hi, I am codesigning my macOS app from terminal (after adding some resources I don't want to copy using Xcode build phases). When I verify the signature using 'codesign -verify', this is OK, but when I run 'spctl -assess', I get 'a sealed resource is missing or invalid'. Leopard supports signed applications to improve its security model. All the system utilities, in fact, come signed by Apple. To sign and check applications, the codesign command line utility is available. For example, to display all information about Terminal.app's code signature, open up a terminal and type. Xattr -cr app codesign -verbose = 4-deep -force -s 'Developer ID Application: ' app The first command removes the complaining attribute and the second deep signs the bundle. Codesign –verify –verbose=4 app file E.g.: codesign –verify –verbose=4 myApp.app. Now package your app into a.dmg (e.g. Then upload the.dmg to Apple’s servers: xcrun altool -t osx -f –primary-bundle-id –notarize-app –username E.g.: xcrun altool -t osx -f myApp.dmg –primary. Verify the signature codesign -verify -vvvv Application.app and spctl -a -vvvv Application.app The code signature workflow At the time of writing it’s not allowed to publish an Electron application to the Mac App Store, so you have to sign it with a Developer ID certificate and ask your users to download and install it manually.

Overview
The hardened runtime was introduced by Apple in macOS 10.14 (Mojave) and while it is optional for applications, it is required in order to notarize your application.
The hardened runtime, along with System Integrity Protection (SIP), protects the runtime integrity of your application software by preventing certain classes of exploits, like code injection, dynamically linked library hijacking, and process memory space tampering. If your application relies on a capability that the hardened runtime restricts, you need to add an entitlement to disable an individual protection. You should only add the entitlements that are absolutely necessary for your applications functionality.
Sandboxing and the hardened runtime prevent an application from doing things it would ordinarily have had permission to do. It should be noted that these two protections are overlapping. The sandbox and the hardened runtime could prevent the same action, so even if the hardened runtime would allow the action, the sandbox may prevent it, and vice versa. See the external links to Apple's lists of hardened runtime entitlements and sandboxing entitlements below.
Hardening your application
The hardening of an application is done during code signing. To harden your application, open a Terminal and run this command:
Hardened runtime entitlements
To allow your application to do something that is now prevented by your hardened runtime, you need to give it that entitlement. You do this by creating an entitlements plist file like this:
This would allow your application to capture movies and still images using the built-in camera. To verify you have a valid plist file, open a Terminal and run the following command:
If the file is properly formatted, the output of that command should be:
To add this entitlement to your application, you need to add it to your code signing command like this:
Verifying hardening
To verify that you have successfully hardened your application, open a Terminal and run this command:
The output of that command should be similar to:
Codesign Verify Mac App Windows 10
The (runtime) flag in the 'CodeDirectory' line indicates that your application is hardened.
To check whether the required hardened runtime entitlements are available, open a Terminal and run the following command:
which should result in the following output:

Gatekeeper is a new security mechanism added to Mac OS X Mountain Lion. Gatekeeper is intended to prevent applications from unknown sources being installed without your knowledge. To work, this new software requires that all applications are signed with a Developer ID provided by Apple. Adobe has been working with Apple and is signing all future applications, including the CS6 products. However, older products released before this new feature (for example, all CS5 and CS5.5 products) have not been signed. Therefore, a Gatekeeper warning message appears when you try to install them on systems running Mountain Lion.
If you'd like to verify the digital signature on older, pre-Gatekeeper Adobe installers, follow the procedures below.
Verify digital signatures for pre-Gatekeeper applications
Creative suite installers (suites and point products) are named “Install.app.' To check the signature on the installer, locate the Install.app file for the installer you want to verify. If you have not enabled the Finder option to display filename extensions, you can't see the .app extension in the Finder.
To confirm that the signature on the file is valid, do the following:
- Open the Terminal from the /Applications/Utilities folder
- In the terminal window, type /usr/bin/codesign -v -vvvv
Note: Do not enter the quotes. It is also important that there is a space after the last v in the command you've entered. Do NOT press return. - Drag the “Install.app” into the Terminal window and then press return. The terminal then displays something like the following:
Codesign Verify Mac
/Volumes/CS5_5 Design Std/Adobe CS5_5 Design Standard/Install.app: valid on disk /Volumes/CS5_5 Design Std/Adobe CS5_5 Design Standard/Install.app: satisfies its Designated Requirement
The second line, 'Satisfies its Designated Requirement' is what confirms that the signature is valid. If the text does not contain this statement, then do not attempt to install the application from this installer. Its security could be compromised.
Additionally, you can also verify who has signed the file:
- type '/usr/bin/codesign -d -vvvv '
- Drag the same “Install.app” into the command window. Again, make sure that there is a space after the last v. And, don't press return until after you've dragged the file. This command outputs something like the following:
Executable=/Volumes/CS5_5 Design Std/Adobe CS5_5 Design Standard/Install.app/Contents/MacOS/Install …
Authority=Adobe Systems Incorporated
Authority=VeriSign Class 3 Code Signing 2010 CA
Authority=VeriSign Class 3 Public Primary Certification Authority - G5

Authority=VeriSign Class 3 Code Signing 2010 CA
Authority=VeriSign Class 3 Public Primary Certification Authority - G5
Signed Time=Mar 29, 2011 11:03:08 AM
If the first 'Authority' line is anything other than Adobe Systems Incorporated, don't trust the installer. It could have been modified after Adobe signed it.
