Fix Adobe Acrobat DC Not Opening on macOS Mojave
Question details
Adobe Acrobat DC and Reader fail to launch or open PDF documents after upgrading to macOS Mojave.
- Product
- Adobe Acrobat DC
- Device & OS
- macOS Mojave
- Scenario
- Attempting to launch Adobe Acrobat DC or open PDF files immediately following a macOS Mojave system upgrade.
- Observed behavior
- The application fails to open and immediately crashes, generating a crash report that cites a code-signature error involving AdobeCrashReporter.framework.
Before modifying system settings or removing files, ensure your macOS Mojave is updated to the latest minor release and close any unresponsive Adobe background processes using the Mac Activity Monitor.
Reset Adobe Acrobat Preferences
Resetting the application preferences to their default states can resolve configuration conflicts that cause Acrobat to crash on launch.
Corrupted preference files are a common cause of application crashes after a major OS update. Removing them forces Acrobat to generate fresh, error-free configurations.
Ensure Adobe Acrobat is completely closed. If it is unresponsive, use Force Quit from the Apple menu.
Open Finder, hold down the 'Option' key, click 'Go' in the top menu bar, and select 'Library'.
Navigate to the 'Preferences' folder and locate files starting with 'com.adobe.Acrobat'. Move these files to the Trash.
Restart your Mac and try launching Adobe Acrobat DC again to see if the issue is resolved.
Test Acrobat in a New macOS User Account
Creating a fresh user account helps determine if the crash is caused by user-specific permission issues or corrupted profile data.
Perform a Clean Reinstall and Check Crash Reports
If Acrobat still fails to open, completely removing and reinstalling the software can fix missing or broken framework files like AdobeCrashReporter.

Frequently Asked Questions
Why does Adobe Acrobat crash specifically on macOS Mojave?
The crash is often caused by compatibility issues between Adobe's internal frameworks (like AdobeCrashReporter.framework) and the updated security or code-signature protocols introduced in macOS Mojave.
Where can I find my application crash reports on a Mac?
You can find macOS crash reports by opening Finder, navigating to 'Go to Folder' (Command+Shift+G), and entering '~/Library/Logs/DiagnosticReports/'. Files here typically end in .crash or .diag.
Will deleting Acrobat preferences delete my PDF files?
No, deleting Adobe Acrobat preference files only resets the application's interface and background settings to their defaults. Your saved PDF documents remain completely unaffected.
