I’m running the 10.12.4 combo update.

I’m still on 10.10.5 and so none of these problems, but …

I just opened Néstor’s link
in Google Chrome. It looked perfect in Chrome. Then I downloaded it to my desktop. The icon on my desktop shows an image of a page with writing on it, but, when I open the document with Skim, it contains nothing but 18 blank pages.

This document has a badly constructed Annotation that coves the whole of the 1st page.

See image.

So I can well understand that if this upsets any software, it’ll happen immediately
and yes 18 blank pages may well be shown.

In Acrobat, with a Ctr-click on that 1st page, one gets the option to Edit or Delete
that Link Annotation.  So it seems to know that there is an error.
(Normally Ctrl-click brings up a menu which allows you to access the Metadata
and other file-related information.)

After deleting it, Preflight reports no PDF syntax issues.

The result is attached here.
Please report if this still shows the same kind of errors.
( ‘cos I cannot tell !! )

This is pretty bad!!!! Fortunately, I am having no problems with LaTeX documents that I am working on.

The metadata does not report this file as having been created by TeX software.
Maybe it has undergone some post-processing, resulting in Metadata
being lost or suppressed.

My conclusion: not an issue regarding LaTeX production of PDFs.

As for Apple?
Well it’s a badly formed PDF, which nevertheless has valid content streams.
It becomes a matter of deciding how to handle badly-formed extra layers
— which it probably isn’t going to show anyway.
You want to just ignore the objects, but that is easier said than done,
the correct syntax hasn’t been followed.



P.S. What I see on Google Chrome. Absolutely nothing translates to Skim.
