Perform a Clean Reinstallation of Acrobat DC
Reinstalling the app directly from the official Adobe download page ensures you are running a version patched for macOS Big Sur compatibility.

Click the Apple menu in the top-left corner of your screen and select 'Restart' to clear out any stalled background processes.
Navigate to the official Adobe Acrobat DC download page (https://helpx.adobe.com/acrobat/kb/acrobat-dc-downloads.html) and download the latest installer for Mac.
Open the downloaded .dmg file and follow the on-screen prompts to complete the installation. Once finished, try launching Acrobat DC again.
Test Acrobat Using a Root or Administrator Account
Enabling a root account helps determine if localized user permissions or corrupted profile settings are preventing Acrobat from launching.

Frequently Asked Questions
Why does macOS Big Sur block some older apps from opening?
Major macOS updates often introduce stricter security protocols and sometimes drop support for older system frameworks. If an application like Acrobat DC isn't fully updated or patched for the new environment, the system may block it from launching to prevent crashes.
Will I lose my PDF documents if I reinstall Acrobat DC?
No, uninstalling and reinstalling Adobe Acrobat DC only affects the software program files. Your personal PDF documents, which are saved locally on your drive or in cloud storage, will remain completely safe.
How do I completely remove Acrobat before reinstalling on Mac?
Simply dragging the app to the Trash might leave behind corrupted preference files. It is highly recommended to download and use the official 'Acrobat Cleaner Tool' for Mac provided by Adobe to thoroughly erase all background processes and cached files before your fresh install.
Can I use a different application to view PDFs while troubleshooting?
Yes, macOS comes with a built-in 'Preview' app that can open and read basic PDFs. For more advanced editing, annotating, and format conversions, you can download a comprehensive free alternative like WPS Office.
