Preview's Blank Comment Bubbles: Troubleshooting Tips and Solutions

Are you experiencing issues with Preview on your Mac, where comment bubbles remain blank? Before we dive into potential solutions, it's essential to consider that the problem might not be with Preview itself but rather with the file you're trying to open. Corrupted files can cause unexpected behavior or prevent them from opening properly.

To test this theory, try opening a different file in Preview. You can export a web page as a PDF using Safari by going to File > Export as PDF. Then, attempt to open that PDF file in Preview. If it opens without any issues, the problem lies with the original file. In this case, you may want to recreate the file from scratch or restore it from an earlier backup when it still worked correctly in Preview.

Another possible cause of problems with Preview could be other apps on your Mac. Some applications that run in the background might interfere with Preview's functionality. Apps that load every time you log in or power up your Mac are particularly likely to cause issues. To test this theory, boot your Mac into Safe Mode by shutting it down, holding the Shift button while powering it back on, and then logging in as usual. If Preview works normally in Safe Mode, it's likely that one of your Login Items is causing the problem.

In this case, follow our guide to remove all your Mac Login Items. By doing so, you should be able to resolve the issue with blank comment bubbles in Preview. Remember to always keep your Mac and apps up-to-date to minimize the risk of encountering similar problems in the future.
