In this article, we will delve into the common reasons why Preview might not work on your MacBook and provide detailed troubleshooting steps to help you resolve the issue. By the end of this guide, you will have the tools and knowledge needed to get Preview back up and running smoothly.
Understanding the Importance of Preview on Your MacBook
Before we delve into the troubleshooting process, it’s essential to understand what makes Preview such an integral part of the Mac experience. Preview is not just a simple image viewer; it serves multiple functions:
- PDF Viewer: You can easily open and view PDF files, annotate them, and fill out forms.
- Image Editing: Preview allows basic image editing tasks such as cropping and resizing.
Given these functionalities, having Preview operational is crucial for many tasks involving documents and images. When it malfunctions, knowing how to address the issue will save you time and stress.
Common Issues That Cause Preview to Malfunction
There can be various reasons for Preview not functioning correctly. Identifying the underlying issue will help you apply the appropriate solution. Here are some of the most common reasons:
Software Updates
One of the primary reasons Preview might stop working is that your MacBook is not updated to the latest version of macOS. Apple frequently releases updates to improve system stability, security, and functionality. Failing to keep your software updated can lead to compatibility problems.
Corrupted Preferences
Sometimes, issues arise from corrupted preference files. These files store settings related to how applications behave. If these files become damaged, Preview may not function as intended.
Document Corruption
If a specific file won’t open or causes Preview to crash, there could be a problem with that particular document. Files can become corrupted for various reasons, including improper shutdowns or incomplete downloads.
Third-Party Applications
Some third-party applications may interfere with Preview’s functionality. This interference can occur due to conflicting software or background processes that disrupt how Preview operates.
Troubleshooting Steps to Resolve Preview Issues
If you’ve run into a problem with Preview, here’s a step-by-step guide to help you troubleshoot and resolve the issue.
Step 1: Check for Software Updates
Keeping your system updated is fundamental to maintaining functionality. Here’s how to check for updates:
- Click on the Apple logo in the top left corner of your screen.
- Select “System Preferences.”
- Click on “Software Update.”
- If updates are available, follow the prompts to install them.
Step 2: Restart Your MacBook
Sometimes, a simple restart can resolve many issues, including application malfunctions.
How to Restart:
Click on the Apple logo in the top left corner and select “Restart.” This action can clear temporary files and shut down background processes that may be interfering with Preview.
Step 3: Reset Preview Preferences
If the issue with Preview persists, resetting its preferences can help.
How to Reset Preferences:
- Close Preview if it is open.
- Open Finder and click on “Go” in the menu bar.
- Hold down the “Option” key and select “Library.”
- Navigate to “Preferences” and look for the file named “com.apple.Preview.plist.”
- Move this file to the Trash (it will be recreated when you reopen Preview).
Step 4: Check for Conflicting Applications
It’s possible that a recent installation of a third-party application is interfering with Preview. To test for this, try the following:
How to Identify Conflicting Applications:
Boot your Mac in Safe Mode by restarting and holding down the “Shift” key until the Apple logo appears. This action starts the system with only essential applications. Try to open Preview in Safe Mode:
- If Preview works, a third-party application is likely the problem.
- To resolve, try uninstalling recently added applications and rebooting normally.
Step 5: Rebuild Preview’s Thumbnails Folder
Preview utilizes a thumbnails folder to enhance performance while browsing files. If this folder becomes corrupted, it can cause issues with the application.
How to Rebuild the Thumbnails Folder:
- Close Preview if it is running.
- Open Finder and go to your “Pictures” folder.
- Locate the “Preview” folder and move the “Thumbnails” folder to the Trash.
Reopen Preview—the system will automatically create a new thumbnails folder.
Step 6: Verify Disk Permissions
Disk permissions errors can also lead to application issues. Use the Disk Utility to check and repair disk permissions.

What should I do if MacBook Preview won’t open?
If your MacBook’s Preview application refuses to open, the first step is to check if it is up to date. Go to the App Store and navigate to the “Updates” tab to see if there are any pending updates for your macOS or Preview app. Installing the latest updates can often resolve compatibility issues that may prevent the app from launching.
If updating doesn’t work, try restarting your MacBook. Sometimes, simply closing all applications and restarting your device can clear up minor glitches or memory issues. If Preview still fails to open, you may need to reset the app preferences by deleting the related files in the Library folder.
Why is Preview crashing on my MacBook?
Preview may crash due to various reasons, including corrupted files or incompatibilities with the version of macOS you are running. One effective way to troubleshoot this issue is to check if the file you are trying to open is damaged. Attempt to open a different file or document to see if Preview works with other items. If it does, the original file might be the cause of the crashes.
Additionally, consider clearing the app caches. You can do this by closing Preview and navigating to the ~/Library/Caches folder in Finder. Locate any folders associated with Preview and delete them. Reopening Preview can sometimes resolve crashes that arise from outdated cache data.
How can I fix issues with PDF files in Preview?
If you are experiencing issues specifically with PDF files in Preview, it is advisable to first attempt opening the PDF using a different app, such as Adobe Reader or a web browser. This can help you determine whether the issue lies with the PDF itself or with Preview. If the PDF works fine in another application, the issue may be with Preview.
For problematic PDFs, consider checking the file integrity. If the PDF is corrupted, you may need to obtain a clean version. You can also try using the “Rebuild PDF” feature available in third-party PDF repair tools, which might help restore it for viewing in Preview.
What should I do if Preview becomes unresponsive?
If Preview becomes unresponsive, the quickest fix is to force quit the application. You can do this by pressing Command + Option + Esc to bring up the Force Quit Applications window. Select Preview from the list and click “Force Quit.” Once the app is closed, wait a moment before reopening it to see if responsiveness has improved.
If Preview frequently becomes unresponsive, check your system resources. Open Activity Monitor and see if your CPU or memory is being heavily utilized by other applications. Closing unnecessary applications or restarting your MacBook can help free up resources, thus improving Preview’s performance.
Why can’t I print directly from Preview?
If you find that you are unable to print directly from Preview, first ensure that your printer is properly connected and powered on. Check if the printer has paper and sufficient ink. Additionally, verify that the correct printer is selected in the Print dialog box when you attempt to print from Preview.
If all hardware checks out, try resetting the printing system. This can be done through System Preferences > Printers & Scanners. Right-click (or Control-click) in the list of printers and select “Reset printing system.” After confirming, add your printer back and attempt to print again from Preview.
How do I restore missing tools in Preview?
If you’ve noticed that certain tools or features in Preview are missing, you may have accidentally hidden them. Start by selecting “View” from the menu bar and checking if any toolbars are unchecked. For example, you can enable the “Markup Toolbar” or other hidden options that you need for your tasks.
If restoring the toolbars doesn’t work, resetting Preview preferences can often bring back missing tools. To do this, close Preview and navigate to the ~/Library/Preferences folder. Locate the file named “com.apple.Preview.plist” and move it to the Trash. Reopen Preview to generate a new preferences file with default settings, which should restore any missing tools.
