How to Fix Acrobat Pro DC Freezes While Editing PDFs on macOS
Question details
Users experience unresponsiveness or application freezes when attempting to review or comment on PDF documents.
- Product
- Adobe Acrobat Pro DC
- Device & OS
- macOS Catalina
- Scenario
- Reviewing, commenting on, or editing PDF files.
- Observed behavior
- The application freezes or becomes entirely unresponsive, preventing the user from successfully saving comments or making modifications to the document.
Verify your internet or local network connection if you are accessing documents from a shared network drive, and ensure you have closed unnecessary background applications on your Mac.
Move the File Locally and Update Adobe Acrobat
Network latency and outdated software are primary causes of freezing. Testing a local copy and installing the latest patches often resolves the unresponsiveness.
Editing files directly from a shared network drive can cause Acrobat to freeze if there are slight interruptions in connectivity. Keeping your application updated also ensures you have the latest bug fixes from Adobe.
If your PDF is stored on a shared network drive or cloud location, drag and drop the file directly onto your Mac's local Desktop or Documents folder.
Open the locally saved PDF in Acrobat Pro DC and try adding comments or making edits to see if the freezing persists.
Click on 'Help' in the top menu bar of Adobe Acrobat and select 'Check for Updates'.
If a newer version (such as 20.009.20063 or later) is available, follow the on-screen prompts to install it, then restart the application.
Temporarily Disable Protected Mode and Enhanced Security
Strict security settings may conflict with specific file structures or network paths, causing Acrobat to freeze during editing.
Add Your PDF or Folder to the Security Whitelist
If you trust the document or the network folder it resides in, adding it to Acrobat's privileged locations allows you to bypass strict security checks without turning off global protections.

Frequently Asked Questions
Why does Adobe Acrobat Pro DC freeze only on specific PDF files?
Specific files might cause freezes if they are excessively large, corrupted, or contain complex layered elements and high-resolution graphics. Testing a completely different, simpler PDF helps determine if the application or the file itself is the root cause.
Does editing a PDF from a shared network drive cause Acrobat to freeze?
Yes. Reading and writing document changes directly over a network connection can cause latency and freezing, especially during auto-saves. It is highly recommended to copy the PDF to your local Mac drive before editing.
Is it safe to disable Enhanced Security in Adobe Acrobat?
Disabling Enhanced Security removes sandboxing protections, leaving your system vulnerable to malicious scripts embedded in untrusted PDFs. You should only disable it temporarily to troubleshoot trusted documents.
How can I whitelist a network folder so Acrobat doesn't freeze?
You can bypass security restrictions for specific trusted folders by navigating to Preferences > Security (Enhanced) > Add Folder Path. This allows Acrobat to trust files within that network folder while maintaining global security features.
