Disable Enhanced Security and Protected Mode
Temporarily disabling these security features can resolve background conflicts that cause the application to hang when loading a PDF.
Adobe Acrobat's Protected Mode restricts the execution of malicious code, but it can sometimes conflict with macOS system permissions, causing the app to freeze. Disabling this temporarily helps identify if security settings are the root cause.
Launch Adobe Acrobat DC, click on 'Acrobat Reader' or 'Acrobat Pro' in the top macOS menu bar, and select 'Preferences'.
In the left-hand sidebar of the Preferences window, scroll down and click on 'Security (Enhanced)'.
Uncheck the boxes for 'Enable Protected Mode at startup' and 'Enable Enhanced Security'.
Close the Preferences window, completely quit Adobe Acrobat Pro DC, and reopen it to test if the PDF opens normally.
Use the Adobe Acrobat Cleaner Tool
If standard reinstallation fails, using the official cleaner tool ensures all corrupted preference files and background processes are completely removed before a fresh installation.
Open PDFs Instantly with WPS Office
If Adobe Acrobat continues to freeze and you need to access your documents immediately, use WPS Office. It is a fast, lightweight alternative to open, read, and edit your PDF files on macOS without performance issues.
- 1. Download WPS Office: Download and install the free version of WPS Office for Mac from the official website.

Frequently Asked Questions
Why does Adobe Acrobat freeze specifically on macOS Catalina and newer?
macOS Catalina introduced stricter security, privacy, and file system permission changes. These strict rules can sometimes conflict with Acrobat's background processes or Enhanced Security features, leading to application hangs or spinning cursors.
Will disabling Protected Mode put my Mac at risk?
Protected Mode limits what PDF files can execute on your system to protect against malicious code. While disabling it temporarily is fine for troubleshooting purposes, you should ensure you only open PDFs from trusted sources while the feature is disabled.
Why didn't reinstalling Acrobat fix the freezing issue initially?
A standard reinstallation usually leaves behind application caches, old preference files, and hidden library configurations. If one of these files is corrupted and causing the freeze, the newly installed app will still load the broken file, which is why the Adobe Acrobat Cleaner Tool is required.
Can I use WPS Office as my default PDF viewer on Mac?
Yes. You can right-click any PDF file, select 'Get Info', change the 'Open with' application to WPS Office, and click 'Change All' to make it your default PDF viewer on macOS.
