How to Fix Acrobat DC Freezing When Adding Text with Fill and Sign
Question details
The user needs to resolve an issue where Adobe Acrobat DC freezes or crashes when trying to add text to a specific location in a PDF contract.

- Product
- Adobe Acrobat DC
- Device & OS
- macOS
- Scenario
- Adding text and filling out a PDF contract using the Fill and Sign tool.
- Observed behavior
- The application completely freezes or crashes when attempting to add text to specific areas of the PDF document.
Before beginning the troubleshooting process, verify if the crashing issue happens with all PDF files or just one specific contract, as this will determine the necessary fix.
Isolate and Remove Damaged Document Elements
Determine if corrupted form fields or annotation objects within the specific contract are causing the application to crash.
Acrobat crashes are frequently caused by damaged underlying code in a specific PDF file rather than the software itself. Overlapping annotations or improperly formatted text fields can trigger a freeze when the Fill and Sign tool interacts with them.
Duplicate the problematic PDF contract in Finder so you can test modifications safely without risking the original file.
Open the copied PDF in Acrobat DC, navigate to the specific page that triggers the crash, and delete any existing form fields, comments, or annotations in that area.
Select the Fill and Sign tool from the right-hand pane and attempt to add text again to see if the crashing persists.

Update Acrobat DC and macOS Environment
Resolve potential compatibility bugs between older Acrobat builds and recent macOS updates.
Fill and Sign PDFs Smoothly Using WPS Office
If Acrobat DC continues to freeze on your Mac, switch to WPS Office. The built-in WPS PDF editor provides a lightweight, highly stable environment to fill forms, add text, and sign contracts without the frustrating crashes.
- 1. Open your PDF contract: Launch WPS Office on your Mac and drag and drop the problematic PDF file into the application.
- 2. Access the Fill & Sign tools: Navigate to the 'PDF' tab at the top and select 'Fill & Sign' or the 'Insert Text' option from the toolbar.
- 3. Add text and save: Click the designated area on the document to type your text securely, apply your signature, and save the finalized contract.

Frequently Asked Questions
Why does Acrobat DC freeze only on a specific page of my PDF?
This usually happens if that specific page contains corrupted form fields, damaged annotation objects, or complex overlapping layers that overwhelm the application's rendering engine.
Will reinstalling Acrobat fix the freezing issue when signing?
Reinstalling might help if the core application files are corrupted. However, if the issue is tied to a specific damaged PDF document, reinstalling Acrobat alone will not resolve the problem.
How can I fill and sign a PDF on Mac if Acrobat keeps failing?
You can use alternative lightweight PDF editors like WPS Office, which natively supports standard PDF form fields, seamless text insertion, and digital signatures on macOS without heavy resource usage.
Can outdated macOS versions cause Acrobat DC to crash?
Yes, compatibility issues between newer builds of Acrobat DC and older macOS versions can cause severe instability, especially when using interactive features like the Fill and Sign tool.
