NSUser class is intended to run unix applications, typically a shell script, from your application. It is intended to execute user-supplied scripts, and will execute them outside of the application's sandbox, if any.
- macOS 10.8+
The class is not intended to execute scripts built into an application; for that, use one of the
AMWorkflow classes. If the application is sandboxed, then the script must be in the
application folder. A sandboxed application may read from, but not write to, this folder.
If you simply need to execute unix scripts without regard to input or output, use
NSUser, which can execute any of the specific types. If you need specific control over the input to, or output from, or the error stream of the script, use this class.
