Tile Windows to Bring the PDF Back On-Screen
Use the built-in Window menu in macOS to reorganize open documents, forcing off-screen windows back into the visible display area.
When a window is pushed off-screen due to resolution changes or disconnected monitors, macOS provides a native tiling feature to snap active windows back into the visible workspace.
Open a few PDF files using Adobe Acrobat DC.
Click the Acrobat DC icon on your Mac's Dock to ensure the application is active and shows in the top menu bar.
Click on the 'Window' menu item at the top of the screen and select 'Tile'.
Choose either 'Horizontally' or 'Vertically' to snap the hidden windows back onto your main screen.

Frequently Asked Questions
Why do application windows disappear off-screen on macOS?
This often happens when disconnecting from a dual-monitor setup or changing display resolutions, leaving the application window mapped to coordinates that no longer exist on the primary screen.
Can I use Mission Control to find the missing Acrobat window?
Yes, swiping up with three or four fingers to open Mission Control can show all active windows. However, if the window is fully displaced off-screen, using the 'Window > Tile' method is usually more effective.
How do I update Adobe Acrobat DC on Mac?
Open Acrobat, go to the 'Help' menu at the top, and select 'Check for Updates'. Follow the on-screen prompts to install the latest version, which may patch this display bug.
Is there a keyboard shortcut to bring off-screen windows back on Mac?
While there isn't a direct 'gather windows' shortcut, you can go to System Preferences > Displays, hold the Option key, and click 'Gather Windows' if multiple displays are detected.
