Gatekeeper on macOS helps protect users from downloading and installing malicious software by checking for a Developer ID certificate from apps distributed outside the Mac App Store. Make sure to sign any apps, plug-ins, or installer packages that you distribute to let Gatekeeper know they’re safe to install. And now, you can give users even more confidence in your apps running on macOS Mojave by submitting them to Apple to be notarized.
Select Certificates in the Server app sidebar. Click and choose Show All Certificates. Click, then choose Create a Certificate Identity from the pop-up menu. In the Name field of the Certificate Assistant, enter your server’s fully qualified host name (for example, server.example.com). Create a self-signed root certificate, export the public key, and generate client certificates using PowerShell on Windows 10 or Windows Server 2016. In the Keychain Access app on your Mac, choose Keychain Access Certificate Assistant Create a Certificate Authority. Brother embroidery layout software mac 2017. Enter a name for the certificate authority. Choose an Identity type, then choose the type of certificate to be issued by the certificate authority.
Prepare for Distribution
A Developer ID certificate lets Gatekeeper verify that you’re a trusted developer when a user opens your app, plug-in, or installer package downloaded from outside the Mac App Store. Software signed with a Developer ID Corporation tax return software mac. certificate can also take advantage of advanced capabilities such as CloudKit and Apple Push Notifications.
Windows App Cert KitGenerate your Developer ID certificate.
You can generate your Developer ID certificate in Xcode or in the Certificates, Identifiers & Profiles section of your developer account. Please note that you must be the Account Holder of your development team in the Apple Developer Program.
Sign and test your app.![]()
Enable the hardened runtime capability and declare entitlements for the functions your app requires in Xcode. Archive your app and test the end-user experience of launching your Developer ID-signed app using a Gatekeeper-enabled Mac.
Xcode
To build your apps for macOS and submit them to be notarized by Apple, use Xcode 10 or later, available from the Mac App Store.
Get Your Software Notarized
Give users even more confidence in your software by submitting it to Apple to be notarized. The service automatically scans your Developer ID-signed software and performs security checks. When it’s ready to export for distribution, a ticket is attached to your software to let Gatekeeper know it’s been notarized.
For step-by-step details on uploading your Mac software to be notarized, read Notarizing Your App Before Distribution and the Xcode Help Guide.
Submitting with Xcode
Unpublished Software. It’s easy to get unpublished software notarized with the Export process or xcodebuild. Custom build workflows are supported by the xcrun altool command line tool for uploading, and you can use xcrun stapler to attach the ticket to the package.
Published Software. To submit software you’ve already published, upload it using the xcrun altool command line tool. Several file types are supported, including .zip, .pkg, and .dmg, so you can upload the same package you already distribute to users.
Viewing Upload Logs
In addition to checking for malicious software, the notary service catches common code signing problems that can prevent your software from installing properly. If notarization fails for your upload, check the status log for details.
Upcoming Requirements
When users on macOS Mojave 10.14 or later first open a notarized app, installer package, or disk image, they’ll see a more streamlined Gatekeeper dialog and have confidence that it is not known malware.
Mac apps, installer packages, and kernel extensions that are signed with Developer ID must also be notarized by Apple in order to run by default on macOS Catalina.

This article explains how to create and export a certificate for app package signing using PowerShell tools. It's recommended that you use Visual Studio for packaging UWP apps and packaging desktop apps, but you can still package an app manually if you did not use Visual Studio to develop your app.
Prerequisites
Create a self-signed certificate
A self-signed certificate is useful for testing your app before you're ready to publish it to the Store. Follow the steps outlined in this section to create a self-signed certificate.
Easy free cad software for mac. Note
When you create and use a self-signed certificate only users who install and trust your certificate can run your application. This is easy to implement for testing but it may prevent additional users from installing your application. When you are ready to publish your application we recommend that you use a certificate issued by a trusted source. This system of centralized trust helps to ensure that the application ecosystem has levels of verification to protect users from malicious actors.
Determine the subject of your packaged app
To use a certificate to sign your app package, the 'Subject' in the certificate must match the 'Publisher' section in your app's manifest.
For example, the 'Identity' section in your app's AppxManifest.xml file should look something like this:
The 'Publisher', in this case, is 'CN=Contoso Software, O=Contoso Corporation, C=US' which needs to be used for creating your certificate.
Use New-SelfSignedCertificate to create a certificate
Use the New-SelfSignedCertificate PowerShell cmdlet to create a self signed certificate. New-SelfSignedCertificate has several parameters for customization, but for the purpose of this article, we'll focus on creating a simple certificate that will work with SignTool. For more examples and uses of this cmdlet, see New-SelfSignedCertificate.
Based on the AppxManifest.xml file from the previous example, you should use the following syntax to create a certificate. In an elevated PowerShell prompt:
Note the following details about some of the parameters:
After running this command, the certificate will be added to the local certificate store, as specified in the '-CertStoreLocation' parameter. The result of the command will also produce the certificate's thumbprint.
Create Cert Request
You can view your certificate in a PowerShell window by using the following commands:
This will display all of the certificates in your local store.
Export a certificate
To export the certificate in the local store to a Personal Information Exchange (PFX) file, use the Export-PfxCertificate cmdlet.
When using Export-PfxCertificate, you must either create and use a password or use the '-ProtectTo' parameter to specify which users or groups can access the file without a password. Note that an error will be displayed if you don't use either the '-Password' or '-ProtectTo' parameter.
Password usageProtectTo usage
After you create and export your certificate, you're ready to sign your app package with SignTool. For the next step in the manual packaging process, see Sign an app package using SignTool.

By adding a certificate to local machine certificate stores, you affect the certificate trust of all users on the computer. It is recommended that you remove those certificates when they are no longer necessary to prevent them from being used to compromise system trust.
