Fix Acrobat DC Crashing During Redaction on macOS High Sierra
Question details
The user is experiencing application crashes in Adobe Acrobat DC right near the end of the redaction process.

- Product
- Adobe Acrobat DC
- Device & OS
- macOS 10.13.3 High Sierra
- Scenario
- Applying and finalizing redactions on a PDF document using a Mac computer.
- Observed behavior
- Acrobat DC unexpectedly crashes near the completion of the redaction process in normal mode, though it functions correctly when the Mac is booted into Safe Mode.
Ensure you have saved any unsaved work in other open applications, as troubleshooting this issue will require restarting your Mac and installing system updates.
Update macOS and Adobe Acrobat DC
Install the latest updates for both macOS and Acrobat, as Apple has addressed specific bugs affecting this redaction workflow in subsequent macOS releases.
Software crashes during memory-intensive tasks like PDF redaction are often caused by OS-level bugs or outdated application versions. Keeping both your operating system and Adobe Acrobat up to date ensures you have the latest stability patches.
Click the Apple menu in the top-left corner of your screen, select 'App Store' (or System Preferences > Software Update), and install any pending macOS updates.
Launch Adobe Acrobat DC, go to 'Help' in the top menu bar, select 'Check for Updates', and follow the on-screen prompts to install the latest version.
Once both updates are complete, restart your computer and attempt the redaction process again.

Isolate Software Conflicts Using macOS Safe Mode
Booting your Mac into Safe Mode helps determine if background applications, login items, or third-party fonts are causing the redaction crash.
Test Alternative PDFs and Collect Crash Logs
If updates and Safe Mode do not resolve the issue, gathering crash logs and testing different PDFs will help isolate file-specific corruption.
Try WPS Office for Stable PDF Management
If your current PDF editor continues to crash on macOS, consider switching to WPS Office. It provides a robust, lightweight PDF editor that runs smoothly on Mac, allowing you to edit, convert, and manage your documents without unexpected system crashes.
- 1. Download the App: Visit the official WPS Office website and download the free version for macOS.
- 2. Open Your PDF: Launch WPS Office and drag your PDF document directly into the workspace.
- 3. Edit Seamlessly: Use the integrated PDF tools to securely modify and manage your files without experiencing performance drops.

Frequently Asked Questions
Why does Acrobat DC crash only during redaction on macOS High Sierra?
This is a documented compatibility issue between certain versions of Acrobat DC and macOS 10.13.3. Apple and Adobe released subsequent patches to address the specific memory rendering conflicts that occur when finalizing redactions.
What does it mean if Acrobat redaction works perfectly in macOS Safe Mode?
If Acrobat successfully redacts documents in Safe Mode, the crash in normal mode is likely caused by conflicting background software, incompatible login items, or corrupt font caches that Safe Mode temporarily disables.
Can a corrupted PDF file cause the redaction tool to crash?
Yes. If a specific PDF contains malformed structural tags, unsupported embedded fonts, or overly complex vector graphics, the redaction processing engine may fail. Testing the redaction tool on a brand-new, simple PDF helps determine if the issue is file-specific.
Where do I find crash logs on my Mac to troubleshoot Acrobat?
You can find application crash logs by opening the 'Console' application located in your Mac's Utilities folder. Look under the 'User Diagnostic Reports' or 'Crash Reports' sections for files specifically related to Adobe Acrobat.
