Fix Acrobat X Pro Crashing When Filling Forms on macOS High Sierra
Question details
Users experience application crashes when attempting to type data into fillable PDF forms.
- Product
- Adobe Acrobat X Pro
- Device & OS
- macOS High Sierra
- Scenario
- Filling out interactive PDF forms for work or personal use.
- Observed behavior
- Acrobat X Pro unexpectedly closes or crashes upon entering form data, and the update server returns Error 1042 preventing further software updates.
Verify your current version of Acrobat X Pro (e.g., 10.1.16) via the Help menu, and ensure you have saved a backup of your blank PDF form to prevent file corruption during crashes.
Upgrade to a Compatible PDF Application
Because Acrobat X is officially unsupported on macOS High Sierra, switching to a modern, supported PDF application is the most reliable way to prevent crashes.
Adobe Acrobat X was released well before macOS High Sierra, leading to severe compatibility issues with Apple's updated system architecture. Because Adobe no longer provides patches for CS6 or Acrobat X, relying on this legacy version will continue to result in form-filling crashes.
Look for modern PDF software that officially supports macOS High Sierra and newer versions. Options include upgrading to an Adobe Acrobat subscription, using Apple's built-in Preview app, or downloading third-party suites.
Right-click your PDF file, select 'Open With', and choose 'Preview'. Preview natively handles basic fillable forms without requiring third-party legacy software.
Click into the form fields to type your data, then press Command + S to save your progress safely without application crashes.
Verify You Have the Final Acrobat X Patch (10.1.16)
Ensure your Acrobat X is updated to the very last release available (10.1.16) to minimize bugs, even though the automatic updater is broken.
Easily Fill and Edit PDF Forms with WPS Office on Mac

- 1. Download and Install WPS Office: Visit the official WPS website, download the Mac version, and install it on your device.

Frequently Asked Questions
Why do I get Error 1042 when updating Acrobat X Pro?
Error 1042 occurs because Adobe has retired the update servers for Acrobat X and CS6 products. The software can no longer connect to the internet to verify or download updates automatically.
Is Adobe Acrobat X Pro compatible with macOS High Sierra?
No, Acrobat X Pro is not officially supported on macOS High Sierra. This underlying system incompatibility is the primary reason the application crashes when processing interactive elements like fillable forms.
Can I fill out my PDF form without buying new software?
Yes. You can use the built-in 'Preview' app on macOS to fill standard PDF fields, or you can download a free office suite like WPS Office, which natively supports viewing and filling interactive PDF forms without crashing.
