When I tried to launch my application from non-gui process (from launch daemon) NSworkspace openApplicationAtURL failed if I tried to run it when my device on the login screen. Everything is working if someone logged in, but on the login screen I have the error The application “TestApp” could not be launched because a miscellaneous error occurred. with code 256 NSWorkspace* workspace = [NSWorkspace sharedWorkspace]; NSWorkspaceOpenConfiguration* config = [NSWorkspaceOpenConfiguration configuration]; config.createsNewApplicationInstance = YES; config.activates = NO; config.promptsUserIfNeeded = NO; config.addsToRecentItems = NO; [workspace openApplicationAtURL: appURL configuration: config completionHandler:^(NSRunningApplication *app, NSError *error) { }]; Sometimes after the third try it works, sometimes not at all. I try to use "open" command, it works on MacOS Sequoia, but not working for operating systems below, I see this error The application cannot be opened for an unexpected reason, error=Error Domain=RBSRequestErrorDomain Code=5 "Launch failed." UserInfo={NSLocalizedFailureReason=Launch failed., NSUnderlyingError=0x600002998120 {Error Domain=OSLaunchdErrorDomain Code=125 "Domain does not support specified action" UserInfo={NSLocalizedFailureReason=Domain does not support specified action}}} All these problems occur only on the login screen. I'm developing screen share utility, so I need somehow to launch my application on the login screen. Could someone please help me understand what is recommended way to launch application on the login screen?
