Frequently Asked Questions
Why does the Forms tool in Acrobat Pro freeze specifically on macOS Catalina?
Freezing often occurs due to compatibility issues between older Acrobat versions and macOS Catalina's system architecture, or due to corrupted application preferences following a recent OS update.
Will I lose my PDF data if I force quit Acrobat Pro?
If you haven't saved your recent changes, force quitting the application will result in the loss of unsaved form data. It is highly recommended to save your work frequently using Command + S.
Can conflicting third-party plug-ins cause Acrobat to crash?
Yes, outdated or incompatible third-party plug-ins can interfere with Acrobat's core features, particularly complex tools like Forms, leading to sudden freezes and unresponsiveness.
How do I report persistent freezing issues to Adobe Support?
When contacting Adobe Support, ensure you provide your exact macOS version (e.g., Catalina 10.15.7), the specific Acrobat Pro version number, a copy of the affected PDF, and the exact steps that consistently reproduce the freeze.
