Update Acrobat and Test with a New User Profile
Installing the latest patches and ruling out user profile corruption are the most effective first steps for resolving frequent crashes on macOS.
Software conflicts within your current macOS user profile or outdated application versions frequently cause Adobe Acrobat to close unexpectedly. Updating the app and testing in a clean environment isolates the root cause.
Open Adobe Acrobat DC, navigate to the top menu bar, and click 'Help' > 'Check for Updates'. Install the latest available version (e.g., 20.009.20065 or newer).
Open 'System Settings' (or System Preferences) on your Mac, go to 'Users & Groups', and add a new user profile with Administrator rights.
Log out of your current account, log in to the newly created Administrator profile, launch Acrobat, and attempt to merge the PDF files again.
Clean Reinstall Adobe Acrobat
Use this solution if standard updates fail, as residual corrupted installation files might be causing the software to crash.
