I have set my Mac to open up all .pdf files with a different app (PDF Expert) instead of the default app (Preview). This works so that when I double-click any PDF, it will open with PDF Expert and not with Preview. I had restarted my Mac after that change. The change goes for any and all PDF files.
In DEVONthink v.2.10 as of June 18, 2018, when I want to open the PDF file, not within DEVONthink but with my default Mac app by pressing Shift-Cmd-O, the file correctly opens with PDF Expert.
However, when I right-click on the file in DEVONthink and choose Open with… then I’m prompted with a long list of options but at the top it shows Preview together with the added info i[/i]. When I select that, then the PDF file opens in Preview.
This seems like a bug to me in the sense that DEVONthink apparently has not updated its list of options from my system and still shows Preview as default instead of showing PDF Expert as the default.
When I right-click on a PDF file on macOS desktop for example, and then choose “Open with…” I correctly see PDF Expert as default being listed at the top of the list of options.
It’s just a cosmetic thing but I thought I’d report this.
