SMLoginItemSetEnabled on child app bundle

If you temporarily pull

My2.app

out of

My.app

, so it’s just a normal standalone app with a XPC login item, does it work then?

No, oddly enough I still get 3: No such process. What does this mean, exactly?

I have tried adding LSRegisterURL directly before, and it succeeds.

Error 3 is almost certainly

ESRCH

, which sounds very much like some OS subsystem is reusing a POSIX-style error code for something that’s not really a POSIX error.

I have tried adding

LSRegisterURL

directly before, and it succeeds.

As this is the first time you mentioned

LSRegisterURL

, I’m not sure how to parse that sentence. My best guess is that:

1. If you take

   My2.app

   out of

   My.app

   …

2. You still see the error 3 when

   My2.app

   tries to call

   SMLoginItemSetEnabled

3. But if you call

   LSRegisterURL

   before

   My2.app

   tries to call

   SMLoginItemSetEnabled

   …

4. Things work

Is that correct?

Are you testing this on your development machine? If so, I suggest you run these tests on a fresh machine each time. Anything related to Launch Services (and the effect of

LSRegisterURL

indicates that this is related to Launch Services) is suspect on development machines. For some background on this, and specific advice on how to test, read this post.
