Hi Prof. Ripley,

Thanks for your reply. Responses inline below.

My apologies on that. 

That is curious and I now see that in looking at the raw message content. I am not sure how that occurred, as I had set the e-mail to plain text when composing, so somehow that changed at some point. What is even more confusing, is that by default, had the e-mail been initially composed as HTML/RTF, it would normally be sent as multipart MIME, which does not appear to have been the case here, leaving me even more confused.

I am sending this now as plain text, so hopefully that is what is sent. I will keep track and if that is not the case, report a bug.

Yes, TeXShop is a GUI front-end previewer as you note below, included in the macTeX distribution, using underlying functionality. Ghostscript 9.55 is also installed as part of macTeX, which I have installed as I still heavily use Sweave to generate PDF reports for clients, some of which use ps-tricks to generate flow chart figures. Thus, the included figure content is generated as PDF and PS/EPS files, which I sometimes quickly preview, until now, using macOS Preview.

There is some coverage now of this change in Preview in various Mac fora, with some hypothesizing that this change in Preview may be security related, pointing to a change by Microsoft in Office back in 2017/2018:


Of course, nothing official from Apple that I have seen.

I also have the full Adobe Acrobat application installed, as I have other functionality provided by that app that I need, so pay for that as a business expense.

It is interesting that now that I am trying to open some PS/EPS files with apps other than Preview, if I use TeXShop, the file opens right away, whereas if I use Acrobat, I get a security pop-up asking me if I trust the source that generated the file, which in this case, is me. Perhaps Apple could take a similar approach with Preview, if security was the motivation for this change, and they elect to revert it.

This was more of a heads up for folks, who like me, have been dependent upon using Preview for a quick look at these files, which are commonly generated using R.

Thanks and regards,
