Preview Not Working on macOS Sierra? Fix It!

On Mac computers, Preview is normally the default PDF tool for editing and carrying out minor modifications on PDF files. Apple usually bundles Preview with its Mac OS X operating system, including the latest version in the series, macOS Sierra. In the current and previous versions, Preview has been known to cause problems for users who need to edit and modify PDF documents. In today’s post, we look at some Preview not working on macOS Sierra issues and what you can do to solve some of them.

Part 1Quick Fixes to Preview on Mac OS X 10.12 Sierra

Problem 1. Frequent In-App Crashes

Preview has been notorious for crashing, even on earlier versions of OS X. Sometimes the problem can be so severe that the application crashes with the computer, forcing you to do a hard restart. This is not only annoying but can result in loss of data and changes that had been made to documents prior to the crash.

Apple has tried to fix the crashing issue with subsequent versions of OS X, though updated versions of Yosemite and El Capitan still continue to register crashes with Preview. You can try to remedy the problem by updating Preview on the App store or refreshing the cache that relates to your fonts by deleting the fonts folder here: Library/Caches/ATS folder.

Problem 2. Password and Encryption Problems

With Preview, users can add passwords and encryptions to the PDF document in order to restrict changes and unauthorized access to the contents. However, the author is also unable to edit the document once the restrictions have been added, which means the original owner can be locked out of their own document. When creating documents, always ensure you maintain a copy of the document in case you need to make changes.

Problem 3. PDF Distortion

Another common problem with Preview is its knack for destroying the structure and content on some types of PDF files. Mac OS X versions 10.9 and earlier do not support PDF files that have been ISO standardized, which causes a host of problems when editing. Inserting text is erratic because Preview does not align the new text with the existing content. Additionally, when saving a document as in ISO-standardized PDF form, it is common for documents to lose aspects of their structure and format.

To remedy such problems, Apple advises users to contact their support team. You can also read through the tons of information online to try and find fixes. But if you are not in the mood to do everything else apart from editing your PDF document, read on for a permanent solution to your problems.
