The Accelerate framework ( amework) contains APIs that help you accelerate complex operations-and potentially improve performance-by using the available vector unit. The following technologies and frameworks are in the Core OS layer of OS X: Accelerate If you need to incorporate code signing into an automated build system or if you link your app against third-party frameworks, refer to the procedures described in Code Signing Guide.įor a complete explanation of code signing in the context of App Sandbox, read App Sandbox in Depth in App Sandbox Design Guide. The steps to take are described in Code Signing Your App in Tools Workflow Guide for Mac. In most cases, you can rely on Xcode automatic code signing, which requires only that you specify a code signing identity in the build settings for your project. Various security technologies, including App Sandbox and parental controls, depend on code signing. After an app is code signed, the system can detect any change to the app-whether the change is introduced accidentally or by malicious code. OS X employs the security technology known as code signing to allow you to certify that your app was indeed created by you.

This is because entitlements, including the special entitlement that enables App Sandbox, are built into an app’s code signature.įor a complete explanation of App Sandbox and how to use it, read App Sandbox Design Guide. When you adopt App Sandbox, you must code sign your app (for more information, see Code Signing). For details on all the entitlements available in OS X, see Entitlement Key Reference. You describe your app’s interaction with the system by setting entitlements in Xcode. The system then grants your app only the access it needs to get its job done, and no more.Īpp Sandbox allows the user to transparently grant your app additional access by using Open and Save dialogs, drag and drop, and other familiar user interactions. Its strategy is twofold:Īpp Sandbox enables you to describe how your app interacts with the system. App Sandbox also minimizes the damage from coding errors. App SandboxĪpp Sandbox provides a last line of defense against stolen, corrupted, or deleted user data if malicious code exploits your app. To learn how to submit your app to the Mac App Store-or test app installation on a Gatekeeper enabled system-read Tools Workflow Guide for Mac. Xcode supports most of the tasks that you need to perform to get a Developer ID certificate and code sign your app. If you plan to distribute your app outside of the Mac App Store, be sure to test the installation of your app on a Gatekeeper enabled system so that you can provide a good user experience. If your app is not signed with a Developer ID certificate issued by Apple, it will not launch on systems that have this security option selected.

Gatekeeper, allows users to block the installation of software that does not come from the Mac App Store and identified developers.

The Core OS layer implements features related to app security.

These services are based on facilities in the Kernel and Device Drivers layer. The technologies and frameworks in the Core OS layer provide low-level services related to hardware and networks.
