How to Fix Missing Scrollbars in Acrobat Reader Preferences on Mac
Question details
The user is unable to see or use scrollbars in the Acrobat Reader DC Preferences window on macOS, preventing access to settings that extend beyond the visible screen.

- Product
- Adobe Acrobat Reader DC
- Device & OS
- macOS
- Scenario
- Trying to access and modify settings in the Acrobat Reader Preferences window.
- Observed behavior
- The scrollbars are missing or hidden, making it impossible to scroll down to view all available preference options.
Ensure your macOS is updated to the latest version and save any open PDF documents before modifying system or application preferences.
Force macOS to Always Show Scroll Bars
Adjusting the global macOS system settings ensures that scrollbars remain visible across all applications, including Acrobat Reader.
By default, macOS may hide scrollbars based on your trackpad or mouse activity. Changing this setting forces them to always be visible, which easily solves the issue of hidden content in the Acrobat Preferences window.
Click the Apple menu in the top-left corner of your screen and select 'System Settings' (or 'System Preferences' on macOS Catalina and older).
Click on 'Appearance' in the sidebar (or 'General' if you are using an older version of macOS).
Locate the 'Show scroll bars' section and select the 'Always' option. Reopen Acrobat Reader to verify the scrollbars are now visible in the Preferences window.

Reduce Display Scaling to Fit the Window
If the Preferences window is too large for your screen, adjusting the display resolution can help fit the entire window on your monitor.
Reset Acrobat Reader Preferences and Update
If the issue is isolated to Acrobat Reader, resetting its preference files and updating the software can resolve UI glitches.

Frequently Asked Questions
Why do scrollbars disappear on macOS by default?
By default, macOS hides scrollbars based on your mouse or trackpad activity to provide a cleaner, minimalist interface. They typically appear only when you are actively scrolling. You can change this behavior to 'Always' in the Appearance or General system settings.
Can I resize the Acrobat Reader Preferences window on Mac?
The Acrobat Reader Preferences window has a fixed minimum size. If your Mac's display resolution is set too low or scaled for larger text, the window may extend beyond the screen, making it impossible to resize manually without changing system display settings.
Will updating macOS fix the missing scrollbar issue in Acrobat?
Updating macOS can resolve compatibility issues with third-party applications like Adobe Acrobat Reader. However, if the issue is simply caused by the 'Show scroll bars' setting being set to 'Automatically based on mouse or trackpad,' an OS update alone won't change this preference.
How do I navigate the Preferences window without a scrollbar or mouse?
You can use the 'Tab' key on your keyboard to move focus through the different options and categories in the Preferences window. Alternatively, using the 'Up' and 'Down' arrow keys can help you scroll through the list of categories on the left pane.
