Hi, I have an application, it has a helper application in its bundle. After the application starts to run, it will launch the helper application process. The helper application process will load a XPCService embedded in its bundle by launchd. But I got an error which is Error Domain=NSOSStatusErrorDomain Code=-10811 "kLSNotAnApplicationErr: Item needs to be an application, but is not" UserInfo={_LSLine=175, _LSFunction=_LSFindBundleWithInfo_NoIOFiltered} How can the helper application launch a XPCService embedded in its bundle? Or the XPCService can only be launched in main application? Thanks

I have an application, it has main process and some child processes. As we want those child processes to have their own minimum sandbox privilege, not inheriting from parent process, we plan to use XPCService which uses a NSTask to launch those child processes, so those child processes can have its own sandbox privilege. We plan to deliver the application to Mac App Store, so process mode is: the sandboxed main process builds connections to the unsandboxed XPCService, the unsandboxed XPCService launch those sandboxed child processes. Can this process mode pass the Mac App Store rules? I see, there is a rule that all processes must be sandboxed, including XPCService. But I tested locally, the Application downloaded from Mac apple store also launches unsandboxed XPCService, like OneDrive. Do you have any suggestions for my application scenario, sandboxed child processes having its own privilege not inheriting from parent?
