Hi,

On my Mac, running MacOS High Sierra 10.13.5 Beta, the example given by Wolfgang works fine: clicking on the link created by ConTeXt, from within TeXShop, Safari opens that document on the desired page, that is the physical page 58.

Best regards: OK

It would, however, be nice if I could further specify on which page of the pdf to open. Is this possible? Or is this a wish not to be fulfilled?
