Fix Adobe Acrobat DC Spinning Beach Ball Hang on macOS Catalina
Question details
The user needs to resolve an issue where Adobe Acrobat DC hangs and becomes unresponsive when opening PDF files.

- Product
- Adobe Acrobat DC
- Device & OS
- macOS Catalina
- Scenario
- Opening PDF documents using Adobe Acrobat DC under a specific macOS user account.
- Observed behavior
- The application freezes, displaying a spinning beach ball cursor, preventing the user from interacting with the PDF, while functioning normally on a different user account on the same machine.
Ensure you have saved all your work in other open applications and have your Mac administrator password available, as you may need it to verify system permissions or apply software updates.
Reset Acrobat Preferences and Clear Application Caches
Clearing corrupted cached data and resetting application preferences is the most effective way to fix account-specific Acrobat freezing issues.
Since the freezing issue is isolated to a single macOS user account, corrupted preference files or cache data in the user's Library folder are likely the culprit. Resetting these files forces Acrobat to generate fresh, error-free settings.
Press the Option, Command, and Esc (Escape) keys simultaneously to open the Force Quit window. Select 'Adobe Acrobat DC' from the list and click 'Force Quit'.
Open a Finder window, hold down the 'Option' key on your keyboard, and click the 'Go' menu at the top of the screen. Select 'Library' from the dropdown menu.
Navigate to the 'Preferences' folder within the Library. Locate any files or folders starting with 'com.adobe.Acrobat' and drag them to the Trash.
Go back to the main 'Library' folder and open the 'Caches' folder. Find the 'Acrobat' folder and move it to the Trash.
Empty the Trash, restart your Mac, and launch Adobe Acrobat DC to see if it successfully opens PDF files without hanging.

Verify Folder Permissions and Install Updates
Ensuring the user account has proper access permissions and that both macOS and Acrobat are up to date can resolve hidden conflicts.
Test with a New macOS User Account
Creating a new user profile allows you to bypass deep-rooted system corruption if the current account is severely damaged.
Use WPS Office as a Stable, Lightweight PDF Alternative
If Adobe Acrobat continues to freeze or consume excessive resources on your Mac, consider switching to WPS Office. It provides a highly stable, integrated PDF reader and editor that operates smoothly on macOS, while also serving as a comprehensive suite for Word, Excel, and PowerPoint files.

Frequently Asked Questions
Why does the spinning beach ball appear only on one Mac user account?
The spinning beach ball indicates that an application is unresponsive. When this happens on just one user account, it usually means that the application's preference files, permission settings, or cached data isolated to that specific macOS profile have become corrupted.
How do I forcefully close Adobe Acrobat DC if it is completely frozen?
You can force quit an unresponsive app on a Mac by pressing the Option, Command, and Esc keys at the same time. This will open the Force Quit Applications window, where you can select Adobe Acrobat DC and click the 'Force Quit' button.
Will updating my Mac fix third-party app crashing issues?
Yes, installing the latest macOS updates and the newest patches for your applications often resolves underlying compatibility issues, patches memory leaks, and fixes known bugs that cause software to hang or crash.
Can I use WPS Office to handle PDFs on macOS?
Yes, WPS Office for Mac features a robust, built-in PDF tool that allows you to easily read, annotate, edit, and convert PDF documents. It serves as a highly efficient and stable alternative to traditional PDF editors.
