Reset Activation Data and Repair Acrobat
Use Adobe's official troubleshooting process to clear corrupted activation data that causes startup issues on macOS.

Quit Adobe Acrobat and ensure any other Adobe Creative Cloud applications currently running on your Mac are fully closed.
Navigate to the official Adobe Help Center article for Mac activation errors and follow the detailed instructions to delete the corrupted licensing cache folders in your system library.
Restart your Mac. Launch Adobe Acrobat again, sign in if prompted, and check for any available software updates for both Acrobat and macOS to prevent future conflicts.

Frequently Asked Questions
Why does Acrobat say "Something went wrong" only after the Big Sur update?
Major macOS updates like Big Sur can change system permissions or folder structures, causing Acrobat's previously cached activation or licensing data to become unreadable, which triggers this specific startup error.
Will simply reinstalling Adobe Acrobat fix this error?
Reinstalling Acrobat often does not resolve the issue because corrupted activation files are usually left behind in the hidden system library folders. You must manually reset the activation data to fix the startup crash.
Are other Adobe applications affected by this macOS update?
Typically, no. In most reported cases, other Creative Cloud applications continue working normally, isolating the issue strictly to Adobe Acrobat's background licensing checks.
How do I find my macOS build number to give to Adobe Support?
Click the Apple menu in the top-left corner of your screen, select "About This Mac", and click on the macOS version number to reveal the specific alphanumeric build number.
