I had a pretty serious disk problem after using this workflow. I think the pairing process somehow corrupted my disk permissions, which prevented my computer from booting up properly—I ended up having to reinstall OS X.
The reason I think this workflow is responsible is that all the permission problems were related to iTunes and one for remote services. Also, the workflow is no longer working for me, after fixing the problem. If you need more information to help figure out what could have happened, please ask!
