I am using the openApplicationAtURL:(NSURL *)applicationURL configuration:(NSWorkspaceOpenConfiguration *)configuration completionHandler:(void (^ _Nullable)(NSRunningApplication *_Nullable app, NSError *_Nullable error))completionHandler function to open the application itself on macOS Ventura.
I need to restart the software itself before it exits. So I call the openApplicationAtURL function to reopen it. But it failed.
In the same code, I can successfully open any other software(As soon as I change the name of the software), but it can not open the software itself.
Is there any way to resolve it?
Sample code:
NSBundle* bundle = NSBundle.mainBundle;
NSWorkspace* workspace = NSWorkspace.sharedWorkspace;
NSWorkspaceOpenConfiguration* configuration = [NSWorkspaceOpenConfiguration new];
NSDictionary* env = @{};
[configuration setEnvironment: env];
[configuration setPromptsUserIfNeeded: YES];
NSString* path = bundle.bundlePath;
[workspace openApplicationAtURL: [NSURL fileURLWithPath: path] configuration: configuration completionHandler:^(NSRunningApplication* app, NSError* error) {
if (error) {
NSLog(@"Failed to run the app: %@", error.localizedDescription);
}
}];
NSWorkspace will, by default, not open an new instance of an app. So, if you call it on yourself, it’s effectively a no-op [1]. Historically the solution here was to have a small helper tool that calls NSWorkspace to launch the app after a short delay. So:
-
Main app starts helper tool process.
-
Main app terminates.
-
Helper tool process launches main app.
-
Helper tool process terminates.
However, on modern systems you can avoid this dance by setting the createsNewApplicationInstance property.

[1] Well, if your app isn’t at the front I think it’ll bring it to the front.
