Fix Adobe Acrobat DC Slow or Freezing When Opening PDFs on Mac
Question details
The user needs to resolve an issue where their PDF reader becomes unresponsive or sluggish when interacting with files or annotations.
- Product
- Adobe Acrobat DC
- Device & OS
- macOS Mojave
- Scenario
- Opening PDF files or viewing document comments.
- Observed behavior
- The application becomes extremely slow, lags noticeably, or completely freezes upon opening the document or accessing the comments section.
Before proceeding, ensure your macOS Mojave system has all recent Apple system updates installed, and verify your internet connection stability if the PDF is stored on a cloud drive.
Isolate the Issue and Update Adobe Acrobat DC
Determine if the issue is isolated to a specific file or version, and apply the latest software patches to fix known bugs.
Performance issues in Adobe Acrobat DC on Mac can often be traced back to an outdated application version or a corrupted specific PDF file. Diagnosing the scope of the problem is the best first step.
Open Adobe Acrobat DC, click on 'Acrobat' in the top Mac menu bar, and select 'About Adobe Acrobat' to note your current version number.
Go to 'Help' > 'Check for Updates' within Acrobat. If an update is available, follow the on-screen prompts to install it and restart the application.
Try opening a few different PDF documents. If only one specific file freezes the app, the file itself may be corrupted or excessively large.
If the freezing PDF is stored on a network drive or cloud storage, copy it to your local Mac desktop and open it from there to rule out network latency.

Frequently Asked Questions
Why does Adobe Acrobat DC run so slowly on my Mac?
Acrobat can run slowly due to outdated software, excessively large PDF files with high-resolution graphics, low system memory, or network latency if the file is stored on a cloud or shared drive.
Does the size of the PDF affect performance?
Yes. PDFs with hundreds of pages, uncompressed images, or complex vector graphics require more RAM and processing power, which can cause the reader to freeze or lag when scrolling or loading comments.
Can I view PDF comments without using Adobe Acrobat?
Absolutely. You can use alternative, lightweight PDF software like WPS Office, which natively supports reading standard PDF files and fully displays all standard annotations and comments left by other users.
How do I stop my Mac from freezing when opening network files?
To prevent freezing, copy the file from the network or cloud drive to your local storage (like your Desktop or Documents folder) before opening it. This bypasses any connection delays.
