How to Fix Adobe Acrobat Accessibility Tool Crashes on macOS
Question details
Users need to resolve an issue where Adobe Acrobat crashes when utilizing accessibility tools on macOS.

- Product
- Adobe Acrobat
- Device & OS
- macOS Big Sur
- Scenario
- Editing reading order, moving tags, or correcting the accessibility structure of a PDF.
- Observed behavior
- Acrobat repeatedly crashes during tag editing, and interactive PDFs exported from InDesign may display missing or damaged structural tags.
Before troubleshooting, save any open documents to prevent data loss and ensure you have administrative credentials for your Mac to install or manage software updates via Creative Cloud.
Update or Roll Back Adobe Software Versions
Software incompatibility between major macOS releases and Adobe apps often triggers crashes. Installing the latest patches or rolling back to a stable older version can resolve the issue.
When Apple releases a major OS overhaul like Big Sur, it can take several months for software developers to fully adapt. If the latest updates do not fix the crashes, downgrading your Adobe Acrobat and InDesign versions is the most reliable workaround.
Open the Adobe Creative Cloud Desktop application and navigate to the 'Updates' tab to install the latest patches for Acrobat and InDesign.
If the software is already updated and still crashing, go to your installed apps list in Creative Cloud. Click the three horizontal dots (More actions) next to Acrobat or InDesign.
Select 'Other versions' from the drop-down menu and choose a stable previous release (such as the 2020 version) to install until a Big Sur-compatible update is released.

Test with Alternative Sources and Repair PDF Tags
The crash may be triggered by corrupted accessibility tags embedded in a specific document rather than a systemic application error.
Submit a Bug Report to Adobe UserVoice
Adobe utilizes a vote-based system to prioritize bug fixes. Reporting reproducible crashes helps engineers identify and patch macOS-specific flaws faster.

Frequently Asked Questions
Why does the Acrobat Accessibility tool crash exclusively on macOS Big Sur?
Major OS updates like macOS Big Sur introduce significant underlying architectural changes. If Adobe has not yet fully optimized Acrobat or InDesign for these changes, memory handling errors can occur when using complex features like the accessibility tag tree, resulting in application crashes.
How do I safely downgrade my Adobe applications on Mac?
Launch the Adobe Creative Cloud desktop app, find Acrobat or InDesign under your installed applications, click the three-dot 'More actions' menu, choose 'Other versions', and select an older release (like the 2020 version) to install.
Can missing tags from InDesign cause Acrobat to crash?
Yes. If an interactive PDF is exported from InDesign with malformed, missing, or corrupt structural tags, Acrobat's accessibility reading order tool may struggle to process the data hierarchy properly, triggering a fatal error and subsequent crash.
