If you’ve decided that your app does need to be signed, and are now equipped with any certificate(s) which you might need, how do you go about signing it?
Ad hoc signing
For all my misgivings over the (lack of) benefits of ad hoc signing, it is very easy to do. If you’ve decided that this is the way ahead, then all you have to do is build the app and type the following into Terminal:
codesign --force --deep -s - MyApp.app
codesign
is the command tool which you use to sign code bundles and apps;--force
ensures that any existing signature is completely replaced with the ad hoc one;--deep

If you have created your own personal certificate and want to use that to sign your app, you’ll need to know the ‘common name’ of your certificate. Check this in Keychain Access, and you’ll find that it’s the name that you gave to your certificate when you created it. The required command becomes:
codesign --force --deep -s 'Personal Code Signing Certificate' MyApp.app
Instead of the hyphen

to indicate that no certificate is to be used, you simply give the common name of your certificate.Signing in Xcode
Xcode is designed to work with Developer IDs and certificates supplied by Apple. Although you can create your own identity and add your personal certificate to it, if you’re using Xcode to manage signing you should really sign up as a developer.
When you do that, you’ll need to add your Developer ID to the list of Apple IDs in the Accounts tab of Xcode’s preferences. For some reason, I have ended up with a ‘personal team’ with the role of user, and my own team as an Agent. My signatures are associated with the latter. When I select it in the list of ‘teams’ and click on the Manage Certificates… button, I can obtain and view all my certificates.
For basic macOS development, there are three different certificates which you’re likely to use:
- Development Certificates or ‘Mac Developer‘, which are supposed to be used during testing and debugging;
- Developer ID Application, which is the main certificate type for apps and other code (except for kernel extensions, which require a special certificate);
- Developer ID Installer, which are used to sign Installer packages, such as those used to install command tools.
You can obtain these directly from the + tool at the foot of this dialog, which is simplest, or online through your developer account.
When you create a new project in Xcode, by default its signing should be set to automatic management, which should in theory work fine. For some reason, mine seems to set the wrong account, and I end up building apps with broken signatures. So I set mine to manual management, selecting the Team and Signing Certificate to use.
Then, during the last part of each build and prior to uploading for notarization, Xcode will automatically ensure all my apps and builds are correctly signed using the selected certificate.
If you are only building the occasional one-off app using Xcode, particularly if you’re using a personal certificate, it is usually simplest to sign it yourself using
codesign
, rather than get befuddled in Xcode’s signing options. If you have a developer ID, then you’ll usually find it better to manage your signing within Xcode. However, you can’t always do that: when I build installer packages, I use Stéphane Sudre’s excellent Packages, and sign the resulting Installer package from the command line using codesign

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.

Mac os sierra best mail app. 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:
/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:
