Error On Mountain Lion #2

Open KingOfBrian opened 12 years ago

KingOfBrian commented 12 years ago

Not sure what this error is, but on mountain lion, I'm getting:

Failed to bless helper. Error: Error Domain=kSMErrorDomainFramework Code=3 "The operation couldn’t be completed. (kSMErrorDomainFramework error 3 - The client and tool did not match requirements.)" UserInfo=0x1001577b0 {NSDescription=The client and tool did not match requirements.}

I got the XPC part working without privilege escalation by using SMJobSubmit instead of Bless. I realize that this is different than the purpose of this demo app, but it's all I need - XPC Between my background menu item and forground viewer.

- (BOOL)startUserAgentWithLabel:(NSString *)label
                          error:(NSError **)error
{    
    CFDictionaryRef job = SMJobCopyDictionary(kSMDomainUserLaunchd, (CFStringRef)label);
    NSLog(@"Job = %@", (NSDictionary *)job);
    if (job == NULL)
    {
        NSMutableDictionary *plist = [NSMutableDictionary dictionary];
        [plist setObject:@"com.apple.bsd.SMJobBlessHelper" forKey:@"Label"];
        [plist setObject:@"com.apple.bsd.SMJobBlessHelper" forKey:@"Program"];
        [plist setObject:[NSDictionary dictionaryWithObject:[NSNumber numberWithBool:NO]
                                                    forKey:@"com.apple.bsd.SMJobBlessHelper"]
                  forKey:@"MachServices"];

        BOOL ok = SMJobSubmit(kSMDomainUserLaunchd, (CFDictionaryRef)plist, NULL, (CFErrorRef *)error);

        return ok;
    }
    return YES;

}

Actually, I retract that. It got a bit farther but was complaining:

Helper available. Sending request: Hi there, helper service. XPC connection invalid, releasing. Received response: (null).

If I wasn't half asleep, I would of noticed ;)

Did you ever figure out the original problem? I got the same exact error myself..

davidsielert commented 11 years ago

OK I figured this out .. You have to change the Identity in the info.plist's (as Nathan Says) and also in the build settings.. Nathan Signed with his appstore certificate which we of course do not have so it will not work

socketwiz commented 11 years ago

I changed my identity in both plist files, the one for the app and the one for the helper, and I also changed the code signing identitys in each project. I still get the error:

Failed to bless helper. Error: Error Domain=kSMErrorDomainFramework Code=3 "The operation couldn’t be completed. (kSMErrorDomainFramework error 3 - The client and tool did not match requirements.)" UserInfo=0x101d20130 {NSDescription=The client and tool did not match requirements.}

Any ideas why it might not be working for me?

socketwiz commented 11 years ago

I can't explain why, but this started working for me when I tried to reproduce the problem so I could post another question on StackOverflow. It could be that I moved the project to another directory and did a clean build. I'm not sure. All I know is not only is this project working for me, but I've been able to also replicate in a project of my own.

A Product -> Clean (shift+cmd+k) may help ;)

Is a Mac Developer profile sufficient for this, or must it be an App Store profile?

davidsielert commented 11 years ago

Mac developer will work

A self-signing certificate suffices. Take a look at: https://developer.apple.com/library/mac/#documentation/security/Conceptual/CodeSigningGuide/Procedures/Procedures.html -- "To use the Certificate Assistant to create a self-signed signing identity"

RudyAramayo commented 11 years ago

Use Developer ID signatures.. apple changed their SMJobBless Samplecode to reflect this based on my DTS response/request

Developer ID will allow the app to run without GateKeeper complaining about an unknown developer...
