- Product
- Adobe Acrobat
- Device & OS
- Mac
- Scenario
- Saving, exporting, or emailing a PDF file using Adobe Acrobat.
- Observed behavior
- A white dialog box appears on the screen, causing the software to become completely unresponsive to clicks or keyboard inputs.
Ensure your Mac is connected to the internet to check for software updates, and save any open work in other applications before attempting to restart the software or system.
Update Acrobat and Disable Online Storage Prompts
The most common cause of the white dialog box is a glitch in the online storage prompt. Updating the app and disabling this feature forces the standard macOS save dialogue to appear.
Launch Adobe Acrobat, go to the Help menu at the top, and select 'Check for Updates'. Install any available updates and restart your Mac.
Open Adobe Acrobat, click on 'Adobe Acrobat' in the top Mac menu bar, and select 'Preferences' (or press Cmd + ,).
In the Preferences window, select the 'General' category from the left-hand sidebar.
Uncheck the boxes next to 'Show online storage when saving files' and 'Show online storage when opening files'.
Click the 'OK' button at the bottom of the window to apply the changes, then try saving a document to confirm the issue is resolved.
Reset Acrobat Preferences to Default Settings
If tweaking the storage settings does not fix the freezing issue, the application's preference files might be corrupted and need a full reset.
Test with a New Administrator Account
If the issue persists, it may be isolated to your specific macOS user profile. Testing on a new administrator account can identify profile-related corruption.

Frequently Asked Questions
Why does a blank white screen appear when I try to save a PDF?
This usually happens when the application fails to properly load its cloud storage interface. Disabling the online storage prompts in the General preferences forces the app to bypass this network check and use the standard macOS save dialog instead.
Will resetting Adobe Acrobat preferences delete my PDF files?
No, resetting your preferences only reverts application-specific settings like default zoom levels, UI layout, and behavioral toggles to their factory defaults. Your saved PDF documents and data remain completely unaffected.
What should I do if Acrobat still freezes after changing the preferences?
If the issue persists, the installation itself might be corrupted. Try uninstalling the application entirely using the official cleaner tool, restart your Mac, and then download and reinstall the latest version directly from the official website.
