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This typically occurs due to corrupted application preference files, outdated software versions, or rendering conflicts with macOS.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.
