    <p>After hell of searching and experimenting I am ready to answer my own question, so others can save their time and efforts.</p> <p>My conclusion is that for now there is no way HelperApp can launch MainApp with some arguments under the Sandbox. At least I have not found any way to do that.</p> <p>Launch MainApp like this:</p> <pre><code>[[NSWorkspace sharedWorkspace] launchApplication:newPath]; </code></pre> <p>In MainApp add the following:</p> <pre><code>Application_IsLaunchedByHelperApp = YES; ProcessSerialNumber currPSN; OSStatus err = GetCurrentProcess(&amp;currPSN); if (!err) { // Get information about our process NSDictionary * currDict = [(NSDictionary *)ProcessInformationCopyDictionary(&amp;currPSN, kProcessDictionaryIncludeAllInformationMask) autorelease]; // Get the PSN of the app that launched us. Its not really the parent app, in the unix sense. long long temp = [[currDict objectForKey:@"ParentPSN"] longLongValue]; long long hi = (temp &gt;&gt; 32) &amp; 0x00000000FFFFFFFFLL; long long lo = (temp &gt;&gt; 0) &amp; 0x00000000FFFFFFFFLL; ProcessSerialNumber parentPSN = {(UInt32)hi, (UInt32)lo}; // Get info on the launching process NSDictionary * parentDict = [(NSDictionary*)ProcessInformationCopyDictionary(&amp;parentPSN, kProcessDictionaryIncludeAllInformationMask) autorelease]; // analyze // parent app info is not null ? if (parentDict &amp;&amp; parentDict.count &gt; 0) { NSString * launchedByAppBundleId = [parentDict objectForKey:@"CFBundleIdentifier"]; if (![launchedByAppBundleId isEqualToString:HELPER_APP_BUNDLE_ID]) { Application_IsLaunchedByHelperApp = NO; } } } </code></pre> <p>That's it. <code>Application_IsLaunchedByHelperApp</code> now has correct value.</p> <p>The solution is not mine. I've found it on the web (cocoabuilder, I guess). Good luck to everyone! And thanks for your attention to my questions.</p> <p><strong>UPDATE</strong> Looks like there are cases when launched at login app shows <code>launchedByAppBundleId = @"com.apple.loginwindow"</code>. So the last part of code will look like this:</p> <pre><code> // // analyze // // parent app info is not null ? if (parentDict &amp;&amp; parentDict.count &gt; 0) { NSString * launchedByAppBundleId = [parentDict objectForKey:@"CFBundleIdentifier"]; if (![launchedByAppBundleId isEqualToString:HELPER_APP_BUNDLE_ID] &amp;&amp; ![launchedByAppBundleId isEqualToString:@"com.apple.loginwindow"]) { Application_IsLaunchedByHelperApp = NO; } } </code></pre>

    1. COIn fact I am surprised that Apple bringing the sandbox and forcing developers to switch to SMLoginItemSetEnabled to get 'LaunchAtStartup' feature, didn't provide any simple way to get notified about MainApp launch environment. Am I naive?

    2. CONaive? I'm cynical and am convinced that these days Apple's motto is "the customer/developer is always wrong" ;-) The reason for not passing arguments in the launch is given as a security risk. The "application groups" (if I've called it the right name) is the mechanism Apple subsequently introduced to allow multiple sandboxed applications to access a shared container, and given that I think you can build what you need. And others found other ways, they all are (or were...) covered somewhere in those forums... but finding things can be a challenge!

    3. COI read about 'application group', but if I remember correctly, you have to ask a special permission from Apple to create it, don't you?

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
