Remove and Reinstall Adobe Acrobat Reader DC
A clean installation often resolves display glitches and corrupt application files that cause the software to render a blank white screen on Mac.
When core application files or preferences become corrupted, specific features like Fill and Sign may fail to load correctly. Uninstalling the app clears out these problematic files, while a fresh download ensures you have the latest bug fixes.
Ensure Adobe Acrobat Reader DC is completely closed. If it is unresponsive on the white screen, press Command + Option + Escape, select the app, and click 'Force Quit'.
Open 'Finder' on your Mac, navigate to the 'Applications' folder, locate 'Adobe Acrobat Reader DC', and drag it to the Trash.
Right-click the Trash icon in your Dock and select 'Empty Trash' to ensure the application files are fully removed from your system.
Visit the official Adobe website and download the latest version of Acrobat Reader DC installer for Mac.
Open the downloaded .dmg file and follow the on-screen prompts to reinstall the application, then test the Fill and Sign feature.
