Fix Adobe Acrobat Crashing When Moving Between Monitors on macOS Mojave
Question details
Users experience unexpected application crashes when dragging PDF document windows, tabs, or tool panels (such as Output Preview) to a secondary monitor.
- Product
- Adobe Acrobat
- Device & OS
- macOS Mojave
- Scenario
- Attempting to manage multiple PDF documents or tool panels across a dual-monitor or multi-display setup.
- Observed behavior
- The Acrobat application crashes instantly and closes without warning when a window or panel crosses over to the secondary monitor display.
Ensure all your open PDF documents are fully saved before testing these solutions, as reproducing this display crash will force-close the application and cause you to lose unsaved progress.
Update Software and Reset Acrobat Preferences
Updating both macOS and Adobe Acrobat, alongside clearing corrupted preference files, often resolves multi-monitor graphics rendering issues.
This multi-monitor crashing bug is frequently tied to specific older builds of Acrobat interacting poorly with macOS Mojave's display drivers. Ensuring you have the latest patches applied is the most reliable way to fix the root cause.
Open System Preferences from the Apple menu and click on Software Update. Install any pending updates for macOS Mojave.
Launch Acrobat, go to the Help menu on the top bar, and select Check for Updates. Follow the on-screen prompts to install the newest compatible build.
Close Acrobat entirely. Open Finder, hold the Option key, and click Go > Library. Navigate to the Preferences folder, locate files starting with 'com.adobe.Acrobat', and move them to the Trash. Restart Acrobat to regenerate fresh preference files.
Use the Tab Dragging Workaround
If updating does not completely resolve the crashes, you can use a specific tab-dragging technique to safely move PDFs to a secondary screen.
Seamlessly View PDFs Across Multiple Monitors with WPS Office
Avoid frustrating macOS Mojave crashes entirely by switching to WPS PDF. WPS Office offers a highly stable, lightweight PDF reader that natively supports multi-monitor setups, allowing you to drag tabs and windows across screens without crashing.
- 1. Download WPS Office: Download and install the WPS Office suite for Mac from the official website.
- 2. Set as Default PDF Reader: Right-click any PDF file, select 'Get Info', choose WPS Office under 'Open with', and click 'Change All'.
- 3. Open PDFs in Tabs: Launch your PDF documents, which will efficiently load in a unified, tabbed interface.
- 4. Drag to Secondary Monitor: Click and drag any PDF tab directly to your secondary monitor to instantly and safely create a new viewing window.
Frequently Asked Questions
Why does Adobe Acrobat crash specifically when moving the Output Preview panel?
On macOS Mojave, older builds of Acrobat have a graphics rendering bug with multi-monitor environments. Floating tool panels like Output Preview fail to redraw properly on a secondary display, leading to an immediate application crash.
Will upgrading my macOS resolve the multi-monitor Acrobat crash?
Yes, upgrading to a newer macOS version (such as Catalina or later), along with installing the latest Adobe Acrobat build, patches the specific display driver conflicts that are prevalent in Mojave.
How do I safely view two PDFs side-by-side on different monitors in Mojave?
Instead of dragging the entire Acrobat application window, open both PDFs as tabs in the primary window. Click and drag only the document tab to your second monitor to create a separate window without triggering the crash.
