I update from OSX El Capitan to macOS Sierra yesterday. Now when I open PDFs containing highlights there are 'double highlights', ie. the original highlight and an additional highlight which is offset slightly. This only happens for some highlights.

See example in picture below. This page should contain 4 highlights (the title of the figure, the p1 and p2 in lower graph, and part of the third last paragraph), but 7 highlights are displayed. Only the last three highlights have "doppelgängers". These additional highlights are offset (down and to the left).

Example of double highlight in macOS Sierra Preview app

Update: Quick Look displays the highlights correctly. See screenshot below. enter image description here

Any suggestions how to fix this?

  • Did you try reporting a bug to Apple? bugreport.apple.com – Alistair McMillan Sep 26 '16 at 12:58

  • I would guess it has something to do with the way the PDF was originally created, and the differences between the plugin that Quick Look uses to generate the preview, and the PDF engine that Preview uses to display the full PDF. – tubedogg Sep 27 '16 at 20:27
  • Apple bugreport: "Engineering has determined that your bug report (28423222) is a duplicate of another issue (27898257) and will be closed." They furthermore write that "Developer has visibility that this is a duplicate via RadarWeb ... Added Duplicate resolution to ADC Notes ...". – bonna Sep 28 '16 at 7:21

    I'm also experiencing problems with highlighting pdfs in Preview on macOS Sierra. - Disappearing highlights, especially when scrolling. - Duplicate or overlaying highlights. - Removing some highlights won't work. The bug report seems pretty dead. Anyone solutions to this unwanted behavior? – cacosomoza Oct 26 '16 at 12:27
