We worked around the earlier bugs in DEVONthink 2.9.8 and will address 10.12.2’s new problems in the upcoming 2.9.9. Eric Bönisch-Volkmann confirmed this, saying ruefully:10.12.2 fixes a few bugs but kills the OCR text layer in PDFs. Brooks Duncan of the DocumentSnap site published a note from one of his readers that warns that the OCR text layer added to scanned PDFs by Fujitsu’s ScanSnap software will be deleted if you edit the PDF in Preview. It’s sad that basic functionality remains broken for so long — especially given that PDF was an area where Apple used to excel.More concerning, and this is what finally pushed me to track down all these reports and write this article, is that the recently released macOS 10.12.2 has introduced a serious new bug related to PDFKit. ![]() If editing a PDF in Preview is unavoidable, be sure to work only on a copy of the file and retain the original in case editing introduces corruption of any sort. Michael Tsai said that some of the bugs he has seen don’t manifest themselves in Preview, suggesting that Apple’s Preview team is aware of the problems and is choosing to work around them rather than getting them fixed in PDFKit itself.It pains me to say this, speaking as the co-author of “ Take Control of Preview,” but I have to recommend that Sierra users avoid using Preview to edit PDF documents until Apple fixes these bugs. We have not had reports of PDFpen causing data loss of documents’ OCR layers.Interestingly, Preview itself may suffer less from bugs in PDFKit than third-party apps. Greg Scown of Smile told me that PDFpen operates independently of PDFKit, butBugs in Preview impact PDFpen customers whose document recipients use Preview rather than PDFpen to view or edit them. And issues reported by Peter Steinberger (author of the PDF framework PSPDFKit) were simply closed with the response that Apple didn’t intend to fix them.Apps that don’t use PDFKit are immune from these problems, of course, but only to the extent that their PDFs aren’t shared more widely and edited in Preview. It's apparently up to version 15 now. For one thing their version numbers are a mess, with DC this and DC that. I try to avoid the Adobe Reader DC versions. I don't like the UI in the newer versions of Adobe Reader (it hasn't been Acrobat Reader for many years now, guys, but I guess old habits die hard). Compared to you guys, though, my needs are pretty basic, like reading Take Control e-books. That said, Reader has always required at least a little tinkering in the toolbar, depending on what features you like to use. It seems to work find in Sierra. Dashlane premium crackThe CS 6 apps work OK in Sierra. But, since I'm not using Creative Cloud, I haven't yet been drawn into their airy-fairy ecosystem. If it ain't broke, don't fix it, which is sadly not part of either Adobe's or Apple's philosophical tool kit.It seems to me that the DC versions of Reader try too hard to get you to use Adobe's cloud services. But, like I said, old habits die hard.
