I'm using Adobe Acrobat DC and used OCR on some of my PDFs, (settings: DPI at least 600, editable text and images) and have noticed that it now takes a very long time for my PDFs to open using mac preview. The text is all there, just takes quite a while to populate. I unfortunately saved the OCR'd version of my PDFs so I cannot start from scratch (with ease). Does anyone have any ideas or fixes? Or will I just have to deal with it?
