How to Remove Adobe Acrobat 9 from macOS Catalina and Fix PDF Printing
Question details
The user needs to completely remove the unsupported Adobe Acrobat 9 application from macOS Catalina to clear out broken file associations and restore PDF printing functionality.

- Product
- Adobe Acrobat 9
- Device & OS
- macOS Catalina
- Scenario
- Upgrading to macOS Catalina causes the 32-bit Acrobat 9 software to stop working, leaving behind outdated PDF printer extensions and file associations that block standard PDF workflows.
- Observed behavior
- Acrobat 9 refuses to run on macOS Catalina due to 32-bit restrictions, and merely deleting the application folder leaves orphaned PDF printer components that interfere with standard printing.
Ensure you are logged into your Mac with an administrator account and close any active PDF viewers before attempting to remove leftover system components.
Use the Adobe Acrobat Cleaner Tool
This is the recommended method to completely eliminate Acrobat 9 components, hidden library files, and broken PDF printer extensions from your Mac.
Since macOS Catalina drops all support for 32-bit applications, Adobe Acrobat 9 will no longer launch. Manually moving the application to the Trash is insufficient because it leaves behind driver files and PDF printing components in the system library.
Navigate to the official Adobe website and download the Adobe Acrobat Cleaner Tool specifically designed for macOS.
Launch the downloaded utility, accept the license agreement, and select Adobe Acrobat 9 from the list to initiate a complete system sweep.
Once the tool finishes processing, restart your Mac from the Apple menu to clear cached file associations and finalize the removal of the old PDF printer drivers.

Run Acrobat 9 via a Virtual Machine
If you absolutely must continue using the older Acrobat 9 interface without purchasing an upgrade, you can emulate an older macOS environment.
Easily View, Edit, and Print PDFs on Mac with WPS Office
Avoid 32-bit application compatibility issues and expensive software upgrades. WPS Office provides a modern, lightweight, and fully 64-bit compatible PDF editor for macOS Catalina and newer versions.
- 1. Download and Install: Get the latest version of WPS Office for Mac from the official website and move it to your Applications folder.
- 2. Set as Default PDF Viewer: Right-click any PDF file on your Mac, select 'Get Info', choose WPS Office from the 'Open with' dropdown, and click 'Change All'.
- 3. Print PDFs Seamlessly: Open your PDF document in WPS Office, click the 'Print' icon or press Cmd+P, and utilize the built-in, error-free PDF printer driver.

Frequently Asked Questions
Why is Adobe Acrobat 9 incompatible with macOS Catalina?
Adobe Acrobat 9 is a 32-bit application. Starting with macOS Catalina, Apple completely dropped support for 32-bit software, meaning only 64-bit applications can be executed by the operating system.
Can I restore PDF printing without upgrading Adobe Acrobat?
Yes. To restore native PDF printing on macOS Catalina without purchasing an Acrobat upgrade, you must thoroughly clean out Acrobat 9's leftover drivers using Adobe's cleaner tool. After restarting, you can use Catalina's built-in print-to-PDF feature or a free 64-bit application like WPS Office.
What happens if I just drag the Acrobat 9 app to the Trash?
Deleting just the application folder leaves behind hidden system files, older 32-bit PDF printer components, and broken file associations. These remnants can interfere with standard PDF printing and viewing across your entire Mac system.
