One of the best apps to handle or edit PDFs on your Mac. PDF Expert is a more powerful solution than the built-in Preview app and more cost-effective than Adobe Acrobat DC.Now, however, it seems Sierra’s PDF-related problems go deeper, and you should exercise caution when editing PDFs with Preview.The first I heard that Sierra’s PDF-related problems might affect more than ScanSnap scanners came in a comment left on one of those articles on 26 October 2016. Those problems turned out to be less severe than initially feared (see “ ScanSnap Conflicts with Sierra Easily Avoided,” 3 October 2016), and Apple resolved them in macOS 10.12.1 (see “ macOS 10.12.1 Sierra, watchOS 3.1, and tvOS 10.0.1 Mostly Fix Bugs,” 24 October 2016). #1577: iPhone 12/12 Pro repair program, fix corrupted Chrome extensions, iCloud Mail custom domains, Chipolo AirTag alternative, 10-digit dialing changesOne of the first problems with macOS 10.12 Sierra revolved around PDFs created by Fujitsu’s ScanSnap scanners (see “ ScanSnap Users Should Delay Sierra Upgrades,” 20 September 2016). #1578: Apple delays CSAM detection, upgrade Quicken 2007 to Quicken Deluxe, App Store settlement and regulatory changes Apple lawsuit decided, Internet privacy limitations, combine Mac speakers
However, throughout the next few months, additional complaints kept surfacing. There have been numerous bug reports sent to Apple on the several serious issues found with PDFKit and we hope Apple addresses them in an upcoming point release.Since Craig Landrum’s comment came after the release of 10.12.1 and the fixes for ScanSnap, I filed his criticism of PDFKit away as something that likely had been true but was no longer. Software that uses third-party PDF libraries probably runs fine, but those of us in the development community who relied upon Apple’s PDFKit library were really slammed — and we have no way to fix the problems ourselves. None have been fixed, as far as I can tell, and I’ve already filed two Radars for new issues in 10.12.2. It’s not only DEVONthink — a lot of other applications (such as EndNote, Skim, Bookends, and EagleFiler) are also affected.In fact, Michael Tsai, developer of EagleFiler, just published a blog post confirming his problems with PDFKit:I ran into a lot of PDF bugs in macOS 10.12.0. And there’s still work left to be done.10.12.2 introduces new issues (it seems that Apple wants to fix at least the broken compatibility now) and of course fixed almost none of the other issues. And to make things worse, lots of former features are now broken or not implemented at all, meaning that we had to add lots of workarounds or implement stuff on our own. However, it was released way too early, and for the first time (at least in my experience) Apple deprecated several features without caring about compatibility. Christian Grunenberg, DEVONthink’s lead developer, characterized the rewritten version of PDFKit in Sierra as “a work in progress,” saying:Apple wants to use a common foundation for both iOS and macOS. Outlook for mac helpBut yes, as soon as you edit a PDF in Preview the text layer is gone. 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. I’ve filed a number of radars with Apple, two of which were closed as duplicates. We’ve worked around that, but in the process had to shut down PDF annotations while we look for workarounds. Versions 10.12.0 and 10.12.1 were bad, but 10.12.2 was a disaster for us, causing Bookends to crash when displaying PDFs with annotations. Reader 2017 Code And IndifferenceWe 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. For instance, PDF documents containing Eastern European characters created by the older ABBYY FineReader 8 engine are corrupted by PDFKit after editing. I’ve never seen such a sorry case of sloppy code and indifference from Apple.Problems with PDF annotations have plagued other developers as well, to judge from irate posts in Apple’s developer forums.Christian Grunenberg laid the blame for the problems at Apple’s feet:Apple supports only a subset of the PDF specification, and that support has always been buggy. ![]() But, like I said, old habits die hard. TidBITS is good enough to make them available in other formats, ePub for iBooks and Mobi for Kindle. 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. I'm using Adobe Reader 11.0.18, which I think is the last pre-DC version. Again I'm no longer into fancy document production, which means I can avoid both Adobe's and Apple's cloud briar patches. The 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.
