How to Hide Acrobat Navigation Pane by Default on Mac
Question details
The user wants to prevent Adobe Acrobat's navigation pane and Signatures panel from opening automatically every time a PDF document is viewed on a Mac.

- Product
- Adobe Acrobat
- Device & OS
- Mac
- Scenario
- Opening and viewing PDF files in Adobe Acrobat where a clean, full-screen document interface is preferred.
- Observed behavior
- The navigation pane or a pinned Signatures panel forcefully appears on the left side of the screen whenever a document opens, taking up valuable reading space.
Ensure your Adobe Acrobat application is updated to the latest version on your Mac, as the Preferences menu layout and panel options may differ slightly in older software releases.
Restore Last View Settings in Preferences
Configure Adobe Acrobat to remember your preferred interface layout, ensuring the navigation pane remains hidden for future sessions.
Open a PDF document in Acrobat. Click the small arrow located on the center-left edge of the window to collapse and hide the navigation pane.
Navigate to the top menu bar, click on 'Acrobat', and select 'Preferences' from the dropdown menu (or press Cmd + , on your Mac keyboard).
In the Preferences window, select 'Documents' from the left sidebar categories. Check the box labeled 'Restore last view settings when reopening documents'.
Click 'OK' to save the changes. Completely close Adobe Acrobat and relaunch it. Reopen your document to confirm the sidebar remains hidden.

Unpin the Signatures Panel
If the navigation pane continues to appear unexpectedly, a pinned Signatures panel may be forcing the sidebar to open automatically.

- 2. Open your PDF document: Launch WPS Office, select 'Open' from the main dashboard, and choose the PDF file you wish to read.
- 3. Customize your reading view: Use the 'View' tab at the top of the screen to toggle interface elements. You can easily close sidebars for a fully immersive, distraction-free reading mode.

Frequently Asked Questions
Why does the navigation pane keep opening when I view a PDF?
Adobe Acrobat often opens the navigation pane automatically if certain panels, like the Signatures or Bookmarks panel, are pinned. It may also default to an open state if the 'Restore last view settings' option is not enabled in your application preferences.
Can I permanently disable the navigation pane in Adobe Acrobat?
You cannot completely disable or remove the navigation pane from the software. However, enabling the 'Restore last view settings when reopening documents' preference allows you to keep it hidden permanently based on your last viewing state.
Will unpinning the Signatures panel delete the digital signatures in my PDF?
No. Unpinning the Signatures panel only hides the menu icon from the sidebar interface. It does not alter the document's contents or remove any existing digital signatures from your PDF.
Is there a keyboard shortcut to hide the navigation pane on Mac?
While there isn't a dedicated single keystroke for the navigation pane specifically on Mac, you can press F4 (or Fn + F4 depending on your keyboard settings) to quickly toggle the navigation pane on and off in Acrobat.
