How to Fix Mac Users Unable to Access Comments in Network Shared PDF Reviews
Product
Adobe Acrobat
Device & OS
Mac
Scenario
A user opens a network-shared PDF that has been pre-populated with review comments, but the comments do not appear for Mac reviewers.
Observed behavior
The PDF opens, but all review comments are absent. The user is also unable to successfully connect to the Acrobat shared review server if a Finder connection to the server is already active.
Before you start

Ensure you have the exact network path or URL to the shared review server and verify that your PDF application is updated to the latest version.

Solution 1Recommended

Disconnect the Server in Mac Finder Before Opening the PDF

Close existing Mac Finder connections to the review server so Adobe Acrobat can establish its own dedicated review session without conflict.

This issue occurs because macOS Finder and Adobe Acrobat attempt to establish competing connections to the same network server. If Finder is actively connected to the shared review server, Acrobat fails to initialize the shared review session properly, causing the comments to remain hidden.

1
Close the PDF application

Fully exit Adobe Acrobat or Adobe Reader on your Mac to ensure no background sessions are active.

2
Open Mac Finder

Click the Finder icon in your Mac Dock to open a new Finder window.

3
Locate the network server

Look under the 'Locations' or 'Network' section in the left sidebar of the Finder window to find the shared review server.

4
Disconnect from the server

Click the 'Eject' icon next to the server name to disconnect from it completely.

5
Reopen the shared PDF

Open the shared PDF document directly. When prompted by the PDF application, enter your credentials to allow the software to connect directly to the review server.

Avoid Concurrent Connections: To prevent this issue from recurring, always avoid maintaining a separate Finder connection to the review server while participating in an active shared PDF review.

Frequently Asked Questions

Why do comments disappear when I open a shared PDF on Mac?

This typically happens due to a network connection conflict. If your Mac's Finder is already connected to the server hosting the PDF, Adobe Acrobat may fail to establish its own review session, causing the embedded comments to remain hidden.

Does this issue affect Windows users accessing the shared review?

Generally, this specific connection conflict is unique to macOS and how Finder handles network drives compared to Windows Explorer. Windows users usually connect to the shared review server without this overlapping connection issue.

How can I verify if my comments were saved to the shared review?

To check if your comments synced properly, check the 'Tracker' feature in Adobe Acrobat (View > Tracker) to see the status of your published comments, or open the PDF on a device that is not currently experiencing the server conflict.
