"But, when I try to open more then one, in High Sierra, they just open in multiple windows, which is bad, bad, bad, bad. Actually, a huge downgrade. Someone know how can I fix it? I already use preferences and didn't worked. I also deleted the Cointeners folder on Library Finder, but didn't work too." Have you encounter the same issue but Preview not working on Mac after you upgrade to macOS 10.14 Mojave? Here is your solution.

Best Alternative to Solve Preview not Working Issue

If you want to continue use Preview, you can try this solution: Copy the PDF after you open the first PDF, and then drag the copy PDF into the other PDFs.

Tips: Top 3 Solutions to Preview Not Working on Mac

We all have every now and then come across one or two bugs and issues at work, behind our computer desks or while working with handheld devices. Preview, the default digital formats, and PDF viewing program on Mac, despite its undeniable practicality and comprehensiveness, is not an exception at all. In this paper, we are going to present to you the 3 most common issues related to Preview not working on Mac the way it's supposed to and discuss the common fixes and introduce one major solution (a perfect equivalent for Preview on Mac OS - PDFelement for Mac). So, if you are ready, let's get started.

Problem 1: Inline Text Editing Issue

Preview sometimes lets us down in applying changes to the text of a PDF. For instance, issues might occur when you want to simply replace a word in a PDF with another word without changing anything else. Preview is most likely disappointing in that respect. I mean even if the PDF is slightly editable in other applications like Adobe Reader, Preview messes up your time and the result is most of the time not satisfactory at all.

Unfortunately, there is nothing much you can do about it inside the Preview itself. Our recommendation to fix this issue is using another application. An easy-to-learn application like PDFelement for Mac. Just Import the PDF you are having an issue with and apply your desired changes and save it as a new PDF. Then open the new PDF with Preview.

Problem 2: Preview Crashes

Crashes suck! Sometimes you spend all day reading and annotating PDFs making educational flash cards (in case you are a college student like me) you can use later for future reference. Preview is highly likely to crash while you are in the middle of reading or have opened a PDF with too many pages trying to annotate a particular page. It has happened to me a lot and it's so gross. This issue is reported commonly by both Yosemite and El Capitan users.

  • Clear the font's cache. Some users have reported that this can make the issue go away, at least temporarily. To do so, go to the Library/Caches/ATS folder and find and delete the font cache folder. For example, if you are the first user defined on your Mac, the folder is named 501. If you are the second user, the folder is named 502.
  • Update your Preview to the latest version using the App Store. Mac developers may have been listening to the growing voice of protest against the malfunctions of Preview.
  • Restart your computer, but remember if you have to do this repeatedly, seriously consider contacting the support team. There might be something critically wrong with your computer.

Problem 3: Preview Can't Select the Text

If you open a scanned PDF document with Preview and decide to annotate it, you notice that the select text tool or the highlight text tool won't work, for instance. You can't apply changes to certain parts of the text or you may end up highlighting the whole page instead! Pretty annoying huh?
