- Product
- Adobe Acrobat
- Device & OS
- macOS
- Scenario
- Configuring a digital ID to sign a PDF document.

Ensure you have saved your current PDF document, as you will need to restart Adobe Acrobat to apply the interface preference changes.
Disable the Modern User Interface for Signing
Reverting to the legacy signing interface typically resolves missing popup dialogs and black overlays in Acrobat on macOS.
Adobe Acrobat introduced a modern user interface for digital signatures, but on some macOS systems, this interface may fail to render properly, causing a black overlay. Falling back to the classic interface is a reliable workaround.
Launch Adobe Acrobat on your Mac. Click on 'Acrobat' in the top Apple menu bar and select 'Preferences', or press the keyboard shortcut Command + Comma.
In the left-hand pane of the Preferences window, scroll down through the categories and select 'Signatures'.
Locate the 'Creation and Appearance' section in the main window and click on the 'More' button next to it.
In the new dialog box, find the option labeled 'Use modern user interface for signing' and uncheck the box.
Click 'OK' to save the changes, completely quit Adobe Acrobat (Command + Q), and relaunch the application to try configuring your digital ID again.
Easily Add Digital Signatures to Your PDFs
If Acrobat's interface issues persist, you can quickly configure digital IDs and sign your PDF documents using WPS Office's reliable built-in PDF tools.
- 1. Open your PDF in WPS: Launch WPS Office on your Mac and open the PDF document you need to sign.
- 2. Navigate to the Protect Tab: Click on the 'Protect' tab in the top ribbon menu to access document security and signature features.
- 3. Add Digital Signature: Select the 'Digital Signature' tool and click on the specific area of the document where you want the signature to appear.
- 4. Configure and Sign: Follow the intuitive on-screen prompts to import an existing digital ID or create a new one, then securely apply your signature to the file.
Frequently Asked Questions
Why does Acrobat show a black screen when I try to sign a document?
This is a known rendering glitch on macOS where the modern signing interface fails to load the popup dialog correctly, resulting in an unresponsive black overlay. Disabling the modern interface in Preferences forces Acrobat to use the stable classic view.
Where are the signature preferences located in Acrobat for Mac?
Unlike Windows where Preferences are under the Edit menu, on macOS you need to go to the top Apple menu bar, click 'Acrobat' > 'Preferences', and then select 'Signatures' from the categories on the left.
Will disabling the modern signing interface affect the legality of my signature?
No. Changing this preference only alters the visual appearance of the dialog box in the software. The cryptographic security, certificate validation, and legal validity of your digital ID remain exactly the same.
