Issues with Endpoint DLP Functionality on macOS Device in Microsoft Purview

Copper Contributor



I recently onboarded a macOS device into Microsoft Purview, but I'm encountering issues with the Endpoint Data Loss Prevention (DLP) functionality not working as expected. Here are the details:


  1. Device Concerned: macOS Ventura 13.4.
  2. Objective: I aim to apply Endpoint DLP policies to:
    • Block the upload of files containing sensitive information to non-trusted sites.
    • Prevent the upload of .csv files to non-trusted sites.
  3. Current Issue: After creating the policies and syncing the device, I found that the Endpoint DLP is not functioning on the macOS device – uploads are not being blocked as they should be.
  4. Steps Taken: I followed the onboarding steps through Intune as per the instructions on Microsoft's documentation page. The Purview management portal shows normal status for both onboarding and policy synchronization.
  5. Comparison: For context, these DLP policies work correctly on a Windows 11 device.


I'm seeking assistance or insights into why these DLP policies are not effective on my macOS device. Any suggestions or guidance would be greatly appreciated.


Thank you!
