Had problem with mac reading ethernet connections...this woman Theresa stuck with me for more than an hour..we did everything including re-installing the OS...she sent the issue to engineers at Apple and today its fixed...I asked to send my praise to her boss and she gave me his email....only Apple has this kind of service...Roku et al have a lot of nothing......This is why Apple is so sucessfull ...she called me back three times to try different things for too many technology companies ...you can't even get them on the phone or their support is in the FarEAST...like Epson et al.
