Update Acrobat DC and Troubleshoot macOS Preferences
Installing the latest updates ensures compatibility with macOS Catalina, while clearing preferences can resolve freezing issues caused by corrupt settings.
Freezes on macOS are frequently caused by outdated software components clashing with the operating system or damaged local preference files. Updating and resetting preferences is the most effective initial fix.
Launch Adobe Acrobat DC. Click on 'Help' in the top menu bar and select 'Check for Updates'. Follow the on-screen prompts to install any available patches, then restart the application.
Open Finder, hold down the 'Option' key, and click 'Go' > 'Library' in the top menu. Navigate to 'Preferences' and locate the folder named 'Acrobat'. Move this folder to the Trash.
Click the Apple logo in the top left corner and select 'Restart'. Once your Mac boots up, launch Acrobat DC again to see if the freezing issue is resolved.

If standard troubleshooting fails, gathering system crash and freeze logs will help technical support identify the specific conflict causing the problem.

Frequently Asked Questions
Why does Adobe Acrobat DC freeze specifically on macOS Catalina?
Major macOS updates like Catalina introduced strict new security and permission structures. If an older version of Acrobat lacks the proper optimization patches, or if its cache files conflict with the new OS structure, it can cause the application to pause or freeze upon opening files.
Can corrupted PDF documents cause my software to freeze?
Yes. If a specific PDF file contains damaged fonts, broken formatting, or excessively large unoptimized graphical elements, the application may struggle to render it, leading to a temporary freeze. You can test this by opening a simple, known-good PDF.
Where can I manually check error logs on my Mac?
You can view application crash and freeze logs by opening the 'Console' app located in the Applications > Utilities folder. Look under 'Crash Reports' or 'Diagnostic Reports' for entries associated with Acrobat to see what might be causing the hang.
Will reinstalling the application fix the freezing problem?
Often, reinstalling can resolve persistent issues by replacing missing or damaged core files. However, it is crucial to use the official application uninstaller rather than simply dragging the app to the Trash, ensuring all problematic preference files are completely removed before reinstalling.
