Clean Uninstall and Reinstall Acrobat DC
Because macOS does not have a built-in repair option for Acrobat, using the Adobe Cleaner Tool ensures corrupted preference files causing the blank gray screen are completely removed.
Standard uninstall methods often leave behind corrupted cached data. Using the official cleaner tool provides a fresh environment for the new installation.
Navigate to the official Adobe website and download the Acrobat Cleaner Tool specifically designed for Mac.
Launch the downloaded tool and follow the on-screen prompts to completely remove Adobe Acrobat Pro DC from your system.
Click the Apple logo in the top left corner and select 'Restart' to clear any remaining temporary files.
Log in to your Adobe Creative Cloud account, download a fresh Acrobat DC subscription installer, and complete the installation to restore the Fill & Sign tool.

Update Acrobat to the Latest Version
A known software bug causing the missing tool or gray screen might have been patched in a recent Acrobat update.
Use WPS Office to Fill and Sign PDFs Seamlessly
Avoid dealing with gray screens and missing tools. WPS Office offers a robust, built-in PDF editor that lets you easily fill forms, add signatures, and edit PDF documents without the heavy resource usage.

Frequently Asked Questions
Why does Acrobat show a blank gray screen when I try to sign a PDF?
This typically occurs due to corrupted application preference files, outdated software versions, or rendering conflicts with macOS. A clean reinstall usually clears the corrupted files and resolves the blank screen.
Where is the Fill and Sign tool supposed to be located in Acrobat?
You can normally access it by clicking the 'Tools' tab at the top left of the Acrobat window, then selecting 'Fill & Sign' from the 'Forms & Signatures' section.
Is there a built-in 'Repair' option for Adobe Acrobat on Mac?
Unlike the Windows version, Adobe Acrobat for Mac does not feature a dedicated 'Repair Installation' button in the Help menu. You must manually uninstall the app using the cleaner tool and reinstall it to achieve the same result.
