Fix Adobe Acrobat DC Not Running After macOS Catalina Upgrade
Question details
The user is unable to launch or use Adobe Acrobat DC on their MacBook Pro after upgrading the operating system to macOS Catalina.

- Product
- Adobe Acrobat DC
- Device & OS
- macOS Catalina
- Scenario
- Attempting to open a PDF application after performing a major macOS system upgrade.
- Observed behavior
- Adobe Acrobat DC fails to open, run, or respond, primarily due to architectural changes and the removal of 32-bit app support in macOS Catalina.
Verify whether your currently installed version of Adobe Acrobat is 32-bit or 64-bit, as macOS Catalina strictly prohibits 32-bit applications from running.
Update to a Catalina-Compatible Version of Acrobat DC
Installing the latest 64-bit update directly from Adobe ensures your Acrobat software meets macOS Catalina's system architecture requirements.
macOS Catalina (version 10.15) entirely dropped support for 32-bit applications. If you were using an older, 32-bit release of Adobe Acrobat DC or Acrobat Reader, it will fundamentally fail to launch on this operating system. Upgrading to the latest 64-bit release is required.
Launch the Adobe Creative Cloud desktop application from your Mac's Applications folder or the top menu bar.
Navigate to the 'Updates' tab on the left sidebar to see a list of applications that have pending new versions.
Locate Adobe Acrobat DC in the list and click the 'Update' button next to it. Wait for the 64-bit version to download and install completely.
Restart your MacBook Pro and attempt to open Adobe Acrobat DC to verify that it now launches properly.

Revert to a Previous macOS Version
If you cannot upgrade your Acrobat license to a 64-bit version, downgrading your Mac to macOS Mojave restores 32-bit application support.
Use WPS Office to Read and Edit PDFs on Mac
If Adobe Acrobat DC remains incompatible or requires an expensive subscription upgrade, WPS Office provides a powerful, native macOS alternative. It includes a robust PDF editor that works flawlessly on macOS Catalina and newer versions.
- 1. Download the Mac Application: Visit the official WPS Office website or the Mac App Store to download the latest macOS-compatible version.
- 2. Set WPS as the Default PDF App: Right-click any PDF file on your Mac, select 'Get Info', expand the 'Open with' section, choose 'WPS Office', and click 'Change All'.
- 3. Open and Edit PDFs: Double-click your PDF file to open it in WPS Office, where you can instantly use the toolbar to highlight text, add comments, or edit document contents.

Frequently Asked Questions
Why did macOS Catalina suddenly stop supporting my Adobe Acrobat?
Apple engineered macOS Catalina to be a strictly 64-bit operating system, entirely removing the architecture required to run legacy 32-bit applications. If your specific version of Adobe Acrobat was 32-bit, the OS physically cannot execute its code anymore.
How can I check if my Mac applications are 32-bit or 64-bit?
Click the Apple logo in the top-left corner, hold the 'Option' key, and select 'System Information'. In the left sidebar under 'Software', click 'Applications'. Look for your app in the list; the column labeled '64-Bit (Intel)' will say 'No' if it is a 32-bit app.
Will older standalone versions of Acrobat (like Acrobat XI or 2015) ever work on Catalina?
No. Adobe has officially ended support for Acrobat XI and Acrobat 2015. They will not receive 64-bit patches. To use Acrobat on Catalina, you must purchase or subscribe to a newer, supported release like Acrobat DC.
