How to Fix Slow Performance and Crashes in Adobe Acrobat on macOS
Question details
The user is experiencing slow performance or startup crashes when using Adobe Acrobat on a Mac, particularly when using external displays or specific third-party plug-ins.
- Product
- Adobe Acrobat 2019
- Device & OS
- macOS Mojave
- Scenario
- Opening Acrobat, changing display settings, or running the application with third-party plug-ins active.
- Observed behavior
- Acrobat runs unusually slowly, crashes at startup due to a CoreGraphics assertion failure, or becomes unresponsive.
Save all open documents in other applications and ensure you have your Adobe account credentials handy, as resetting preferences may require you to sign back in.
Update Software and Disable Third-Party Plug-ins
Plug-ins like Enfocus PitStop Pro and Quite Imposing Plus are common culprits for crashes on macOS. Disabling them temporarily helps isolate the issue.
Running outdated versions of macOS or Adobe Acrobat can cause severe compatibility issues. First, ensure your system is fully updated, and then isolate the problem by removing third-party additions.
Update macOS by navigating to System Preferences > Software Update. Update Acrobat by opening the application and selecting Help > Check for Updates.
Open Finder and navigate to your Acrobat Plug-ins folder, typically located at /Library/Application Support/Adobe/Acrobat/[Version]/Plug-ins.
Select the third-party plug-in files (like Enfocus PitStop Pro) and move them to a temporary folder on your Desktop.
Restart Adobe Acrobat to see if the crashing or slow performance persists. If the issue is resolved, check with the plug-in developer for a macOS Mojave compatible update.
Reset Adobe Acrobat Preferences
Corrupted preference files can cause Acrobat to freeze or crash unexpectedly upon startup.
Temporarily Disable Antivirus Scanning
Aggressive real-time antivirus scans can interfere with Acrobat's CoreGraphics processes, leading to assertion failures.

Frequently Asked Questions
What causes the CoreGraphics assertion failure in Acrobat on macOS?
This error usually occurs on macOS Mojave due to conflicts between Acrobat's rendering engine and third-party plug-ins, or when switching between external displays. Updating or disabling these plug-ins often resolves the issue.
Where can I find the crash reports for Adobe Acrobat on my Mac?
You can find crash reports by opening the 'Console' app (located in Applications > Utilities) and navigating to 'User Reports' or 'Crash Reports'. Look for logs starting with 'Acrobat' to identify conflicting modules.
Will resetting my Acrobat preferences delete my PDF files?
No, resetting preferences only restores the application's default settings (like toolbars, recent file lists, and viewing modes). Your saved PDF documents and local data will remain completely unaffected.
Can antivirus software really cause PDF readers to crash?
Yes. Real-time scanning features in antivirus software can sometimes lock application files temporarily while analyzing them, leading to timeouts, slow performance, or crashes in resource-heavy apps like Acrobat.
