Fix PDF Drag and Drop Issues in macOS Catalina (Acrobat)
Question details
The user needs a way to drag and drop or attach PDF files to other applications after upgrading to macOS Catalina, as the usual title bar icon is missing.

- Product
- Adobe Acrobat
- Device & OS
- macOS Catalina
- Scenario
- Attempting to drag an open PDF file directly from the application into an email draft or another program.
- Observed behavior
- The small PDF proxy icon beside the document title in the application header is no longer available for dragging attachments.
Ensure your macOS is updated to the latest Catalina patch and verify that your destination application (such as Apple Mail) has the necessary file access permissions in your Mac's System Preferences.
Locate the PDF in Finder to Drag and Drop
Since the proxy icon is missing from the title bar, the most reliable workaround is to drag the file directly from its saved location in Finder.
Apple changed how proxy icons behave in recent macOS updates, which affects third-party apps like Adobe Acrobat. Saving the file locally and using Finder completely bypasses this interface limitation.
Ensure the PDF you are currently viewing is saved locally to your Mac's hard drive.
In Adobe Acrobat, go to the top menu bar, click on 'File', and select 'Reveal in Finder'. This will immediately open a Finder window highlighting your document.
Click and hold the highlighted PDF file in the Finder window, then drag it directly into your email compose window or destination application.

Use Built-in Share or Attach Commands
You can avoid manual drag-and-drop actions entirely by utilizing the application's built-in sharing features.
Verify macOS App Permissions
Sometimes drag-and-drop fails not just because of missing icons, but because macOS Catalina's strict security settings are blocking cross-app file sharing.
Use WPS Office to Easily Manage and Share PDFs on Mac
WPS Office for Mac includes a powerful built-in PDF editor that allows you to read, edit, and seamlessly share PDF files directly to your email without worrying about missing macOS proxy icons or drag-and-drop glitches.
- 1. Open your PDF in WPS Office: Launch WPS Office for Mac and open the PDF document you wish to share.
- 2. Access the Share Menu: Click on the 'Menu' button or locate the dedicated 'Share' option in the top navigation bar.
- 3. Select Email Sharing: Choose the 'Email' option from the dropdown menu to instantly create a new message with the PDF attached.
- 4. Send the Document: Fill in your recipient's email address in your default mail application and click send.

Frequently Asked Questions
Why did the proxy icon disappear in macOS Catalina?
In macOS Catalina and subsequent versions, Apple redesigned the user interface and hid the title bar proxy icon by default to create a cleaner look. Users typically need to hover their cursor over the document name and wait a moment for the icon to appear.
Can I restore the classic proxy icon behavior in newer macOS versions?
Yes, if you upgrade to macOS Big Sur or Monterey, you can go to System Preferences > Accessibility > Display, and check 'Show window title icons' to make them visible without hovering. In Catalina, hovering or using Finder is usually required.
Does this drag-and-drop issue affect all applications on Mac?
This change primarily affects applications that use standard macOS window title bars. However, third-party apps with custom interfaces, like some versions of Adobe Acrobat, might lose the hover-to-reveal functionality entirely, requiring you to use Finder or built-in share buttons instead.
How do I change my default email app for the 'Attach to Email' button?
You can change your default email reader by opening Apple Mail, going to Mail > Preferences > General, and selecting your preferred email application (like Outlook or Spark) from the 'Default email reader' dropdown menu.
