I get message Hello, Your request to use Endpoint Security was approved for Development only. You will need to enable two capabilities for your Bundle ID. Click Identifiers in the sidebar, then select the Mac App ID that you will use for Endpoint Security. Under Capabilities, enable System Extension. Under Additional Capabilities, enable Endpoint Security. Click Save in the top-right of the page, review the alert that appears, and confirm if you accept the changes. Then generate a new Development provisioning profile for your App ID by clicking Profiles in the sidebar and the Add button (+) in the upper-left corner. Once your profile has been created, you'll need to configure your Xcode project for manual code signing. If your Xcode project doesn't already have an entitlements file, create a new property list file and change its extension from .plist to .entitlements. Add the keys and values of the entitlements used in your project to the .entitlements file, then follow the rest of the Xcode manual signing process. For troubleshooting, see Technote 2415 Entitlements Troubleshooting and Debugging Entitlement Issues. If you need additional support, visit the Apple Developer Forums or submit a Technical Support Incident. Best regards, Apple Developer Relations i created a distribution profile,but no endpoint-security entitlement in it. how do i get a distribution profile with endpoint-security entitlement.
