Here's information on Craig Federighi, one of Apple's top men:-

There is a software facility called EtreCheck, supposedly developed and marketed by a Mr John Daniel of a company called Etresoft, Inc, Canada.
Can anyone reading here provide confirmation that he is just as genuine a figure as Mr Federighi?
Thanks if you can.
