Fix Adobe Acrobat or Reader Quitting Unexpectedly on macOS Catalina
Question details
Adobe Acrobat or Acrobat Reader immediately crashes or displays an error message stating it quit unexpectedly when trying to open on macOS Catalina.
- Product
- Adobe Acrobat / Acrobat Reader
- Device & OS
- macOS Catalina
- Scenario
- Attempting to launch the Adobe Acrobat application or open a specific PDF file on a Mac running Catalina.
- Observed behavior
- The application fails to load or crashes immediately upon opening, returning an 'Acrobat Reader quit unexpectedly' error.
Verify that your macOS Catalina and Adobe Acrobat are updated to their latest supported versions. Restarting your Mac and attempting to open a different PDF file first can sometimes bypass temporary application freezes.
Perform a Clean Uninstall and Reinstall of Acrobat
Use the official Acrobat Cleaner Tool to completely remove damaged application files and corrupted preferences before installing a fresh copy.
A standard drag-to-trash uninstallation leaves behind deep system preferences and support files that often cause crashes to persist. Using the official cleaner utility ensures a completely fresh start.
Download the official Acrobat Cleaner Tool for Mac from the Adobe Labs website. Run the utility to safely and fully uninstall the application.
Open Finder. From the top menu, select 'Go' > 'Go to Folder'. Navigate to '/Library/Application Support' and '~/Library/Application Support', then delete all Adobe folders.
Using the 'Go to Folder' menu again, navigate to '/Library/Preferences' and '~/Library/Preferences'. Locate any Adobe-related preference files and move them to the Trash.
Restart your Mac computer to clear the system cache. Visit the official Adobe download page to download the latest Acrobat installer, run it, and sign in to activate.
Test with an Alternative PDF File or User Profile
Determine if the unexpected quitting is caused by a heavily corrupted PDF file or a damaged macOS user account rather than the application itself.
Try WPS Office as a Stable PDF Alternative on Mac
If Acrobat continues to crash on macOS, WPS Office offers a highly stable, lightweight, and free alternative. It includes a powerful PDF toolkit along with Word, Excel, and PowerPoint alternatives.
- 1. Download WPS Office for Mac: Visit the official WPS Office website and download the macOS installation package.
- 2. Set as Default PDF Viewer: Right-click any PDF file, select 'Get Info', change the 'Open with' application to WPS Office, and click 'Change All'.
Frequently Asked Questions
Why does Acrobat Reader quit unexpectedly on macOS Catalina?
This issue is most frequently caused by corrupted Adobe preference files, damaged installation files from a recent system update, or incompatibility issues within your macOS user profile.
How do I safely remove Adobe preference files on my Mac?
Open Finder, select 'Go to Folder' from the 'Go' menu, and type '~/Library/Preferences'. Locate any files or folders starting with 'com.adobe' and move them to the Trash. Repeat this process for the system-level '/Library/Preferences' folder.
Will a standard reinstall fix the crashing issue?
A standard reinstall might not resolve deep-rooted issues because damaged preference files remain on your system. It is highly recommended to use the official Acrobat Cleaner Tool to completely wipe residual files before installing a fresh copy.
Can a specific PDF file cause Acrobat to crash on Mac?
Yes, a heavily corrupted, excessively large, or unusually formatted PDF file can trigger an immediate application crash. Testing with a different, known-working PDF file helps determine if the software crash is file-specific.
