: Allthough a new pdf is created, this is not opened. If the pdf is open in Preview already, it is not updated unless switching to the Preview application.
It something wrong here? Is it not functional in MacOS? Am I missing some clue?
Apple’s Preview updates only on activation, and not reliably (for me, it often crashes).
One can use the command 'open <filename>', which opens it. In some versions of Preview, one get an extra copy so that they must eventually be all closed by hand.
That it doesn’t update in the background is more a feature than a bug, otherwise it would complain about broken/unavailable files during the TeX runs.
It is likely a bug: It has worked in some past versions.
