Hi Stephane,
A few things you might check...
1) You have set a delegate for the NSNetServiceBrowser instance you have created.


Yes.

2) The delegate you have set indeed implements the delegate method with the correct method signature.


AFAIK, yes.

2) You have done a search for services using the instance created and have not sent the stop message to the instance.


Yes.

3) Your code is in a run-loop.

That's a good question. I don't do anything to add the NSNetServiceBrowser to a run-loop. I assume from the documentation that it's automatically added to the current run-loop and that you can remove it or move it to another run-loop if needed.

The test I'm doing is the following one:

1. Search for _workstation._tcp.

2. Wait for the results

3. Connect to a remote Mac using ARD.

4. Change the IP of the Mac. (Quit ARD).

5. Wait for anything to happen in the sample code.
