How to Fix Adobe Acrobat Crashes After Upgrading to macOS Catalina
Question details
The user needs to resolve an issue where Adobe Acrobat Pro continuously crashes or fails to launch after the Mac operating system was upgraded to Catalina.

- Product
- Adobe Acrobat Pro
- Device & OS
- macOS Catalina
- Scenario
- Upgrading an older Mac operating system from macOS Mojave to macOS Catalina while retaining legacy applications.
- Observed behavior
- Adobe Acrobat Pro crashes immediately upon opening due to conflicts between the older 32-bit application architecture and the strict 64-bit requirement of macOS Catalina.
Before proceeding with troubleshooting, check your exact Adobe Acrobat version number and verify whether you possess the original installation files or account login details in case a complete reinstallation is required.
Upgrade to a 64-Bit Compatible Version of Acrobat
Since macOS Catalina completely drops support for 32-bit applications, installing a newer, 64-bit release of Adobe Acrobat is the most reliable way to prevent crashes.
Apple's macOS Catalina strictly requires all applications to be 64-bit. If you are running an older version of Acrobat Pro designed for 32-bit systems (like Acrobat XI or older Classic tracks), the OS will block it from running properly, resulting in crashes.
Click the Apple logo in the top-left corner of your screen, select 'About This Mac', click 'System Report', and navigate to the 'Applications' section to verify if your Acrobat version is listed as 64-bit.
Open the 'Applications' folder, locate the Adobe Acrobat uninstaller within its folder, and run it to remove the legacy 32-bit software from your system.
Log into your Adobe account online or open the Creative Cloud Desktop application to download and install a modern, Catalina-compatible release like Acrobat DC.

Downgrade to macOS Mojave and Perform a Clean Reinstall
If you must continue using an older 32-bit version of Acrobat Pro, you will need to roll back your Mac's operating system to Mojave and cleanly reinstall the Adobe software.
View and Edit PDFs on macOS Catalina Using WPS Office
If your older PDF software is no longer compatible with macOS Catalina and you prefer not to pay for a costly upgrade, WPS Office provides a powerful, built-in PDF editor that runs natively and stably on modern 64-bit macOS versions.
- 1. Download WPS Office for Mac: Visit the official WPS website and download the macOS-compatible installation package.
- 2. Install and launch the application: Drag the WPS Office icon to your Applications folder, then launch the program from your Launchpad.
- 3. Open your PDF file: Click 'Open' on the WPS home screen and select the PDF document you were previously trying to access.
- 4. Edit and manage your document: Use the dedicated PDF tab in the top ribbon to add text, insert comments, highlight sections, or convert the PDF to a Word document.

Frequently Asked Questions
Why does macOS Catalina block older applications from opening?
Apple engineered macOS Catalina to be a strictly 64-bit operating system to improve performance and security. As a result, older 32-bit applications lack the necessary system frameworks to execute, causing them to either display an incompatibility warning or crash instantly upon launch.
How can I tell if an application on my Mac is 32-bit or 64-bit?
Hold down the Option key and click the Apple menu, then select 'System Information' (or 'System Report'). Scroll down the left sidebar to the 'Software' section and click 'Applications'. In the right pane, look at the '64-Bit (Intel)' column; if it says 'No' next to the application, it is 32-bit and will not work on Catalina.
Will I lose my PDF files if I uninstall a crashing version of Acrobat?
No, uninstalling a PDF application only removes the software executable and its preferences. Your actual PDF documents are saved separately on your hard drive and will remain intact, ready to be opened by any compatible PDF reader.
