Trying to create a Platypus-Like App that runs as launchd startup.

[peetinc]

Catalina blocks any Platypus-built apps I try to use as a LaunchDaemon/LaunchAgent (at the login window). Something just stops them from firing. See here.

I 'wrote' a simple app to just launch a 'script' file in resources. It works and will be adequate, but I'd very much like to double-click, authenticate as an admin and have it run as root ...

#import <Cocoa/Cocoa.h>
#import "STPrivilegedTask.h"

int main(int argc, const char * argv[]) {
@autoreleasepool {
    NSTask *script = [[NSTask alloc] init];
    [script setLaunchPath:@"/bin/zsh"];
    [script setArguments:@[ [[NSBundle mainBundle] pathForResource:@"script" ofType:nil] ]];
    [script launch];
}
   return 0;
}

I have virtually no Objective-C or coding experience beyond shell scripting, but I'm trying. My hope was to have something like this,

#import <Cocoa/Cocoa.h>
#import "STPrivilegedTask.h"

int main(int argc, const char * argv[]) {
@autoreleasepool {
    
   STPrivilegedTask *privilegedTask = [[STPrivilegedTask alloc] init];
   [privilegedTask setLaunchPath:@"/bin/zsh"];
   [privilegedTask setArguments:@[@"script"]];
  
   // Setting working directory is optional, defaults to /
   NSString *path = [[NSBundle mainBundle] resourcePath];
   [privilegedTask setCurrentDirectoryPath:path];
  
   // Launch it, user is prompted for password
   OSStatus err = [privilegedTask launch];
   if (err == errAuthorizationSuccess) {
       NSLog(@"Task successfully launched");
   }
   else if (err == errAuthorizationCanceled) {
       NSLog(@"User cancelled");
   }
   else {
       NSLog(@"Something went wrong");
   }
  
}
   return 0;
}

But this will not pop an authorization for the end user and always returns

I'm sure I'm missing something that is blatantly obvious to anyone who knows what they are doing.

Thanks for any help.
