Preview not searching PDFs under macOS Mojave?
Wondering if anyone else is having this problem: if I open a PDF from my Zotero library in Preview, it will not show results for any terms. It will work fine if I either open it in Acrobat Reader or move the PDF file out of the Zotero library to another location.
What happens if you use Show File and then open the PDF in Preview directly?
Is your Zotero data directory at /Users/:user/Zotero?
