How to Fix PluginProcess Requesting Access to Acrobat Confidential Information on Mac
Question details
A security prompt appears on Mac requesting PluginProcess access to Acrobat's confidential information.

- Product
- Adobe Acrobat Pro DC
- Device & OS
- Mac
- Scenario
- Using Adobe Acrobat Pro DC or modifying Safari preferences after a recent application update.
- Observed behavior
- The macOS system displays a Keychain access prompt asking to allow 'PluginProcess' to access confidential information stored for v4.services.acrobat.com.
Before making any changes to your Keychain or granting permissions, ensure that your macOS and Adobe Acrobat Pro DC are updated to the latest versions to rule out known security bugs.
Review and Handle the Security Prompt Safely
Verify the source of the prompt before granting or denying Keychain access to PluginProcess to maintain system security.
This prompt frequently appears when Safari preferences are used to remove stored cookies or website data, forcing Adobe web extensions to re-authenticate.
Check if you recently cleared Safari cookies or website data, which often triggers this Adobe authentication prompt in the background.
Ensure you are actively running Adobe Acrobat Pro DC or interacting with an Adobe-related Safari plugin when the message appears on your screen.
Click 'Deny' if the prompt appears randomly when you are not using Adobe services. Click 'Allow' or 'Always Allow' only if you recognize the action and trust the Adobe request.

Clear Outdated Adobe Keychain Entries
Removing outdated Adobe cached credentials can prevent recurring phantom authentication requests.
