Will Acrobat Pro 2017 or DC Run on macOS 10.15? Compatibility Guide
Question details
The user needs to know if Adobe Acrobat Pro 2017 or Acrobat DC is compatible with macOS 10.15 (Catalina) due to the operating system's strict 64-bit application requirement.

- Product
- Adobe Acrobat Pro 2017 / Acrobat DC
- Device & OS
- macOS 10.15
- Scenario
- Upgrading a Mac to macOS 10.15 and checking if existing PDF software will continue to function.
- Observed behavior
- Older versions of Acrobat or unpatched installations may fail to install or run correctly on macOS 10.15 because they contain unsupported 32-bit components.
Verify your current version of Adobe Acrobat and check your Mac system settings to confirm if you have already upgraded to macOS 10.15 Catalina.
Update to the Latest Supported Acrobat Build
To ensure Adobe Acrobat Pro 2017 or Acrobat DC runs on macOS 10.15, you must install the latest updates to achieve full 64-bit compatibility.
macOS 10.15 Catalina introduced a 64-bit-only application environment. Because of this, older versions of Acrobat with 32-bit architecture will not launch. Upgrading to the latest supported patches of Acrobat 2017 or DC is required.
Visit the official Adobe support website and review the macOS Catalina compatibility matrix. Verify that your specific Acrobat build and macOS release are listed as fully supported.
Open Adobe Acrobat Pro 2017 or Acrobat DC. Navigate to the 'Help' menu at the top of the screen and select 'Check for Updates' to download and install the latest 64-bit patches.
If you rely on third-party PDF plug-ins, contact their developers to confirm they are 64-bit compatible. Any 32-bit plug-in will fail to load in macOS 10.15.
Before upgrading your primary workstation to macOS 10.15, install and test your Acrobat DC or 2017 workflows on a secondary test machine to ensure there are no unexpected crashes or feature limitations.

A Lightweight PDF & Office Alternative for macOS
If you are experiencing compatibility issues with older PDF software on macOS 10.15 Catalina, consider switching to WPS Office. It provides a built-in, natively 64-bit compatible PDF editor alongside fully-featured Word, Excel, and PowerPoint alternatives—all optimized for modern Mac systems without heavy subscription fees.

Frequently Asked Questions
Why does macOS 10.15 not support older versions of Adobe Acrobat?
macOS 10.15 (Catalina) dropped support for 32-bit applications entirely to improve system performance and security. Older versions of Adobe Acrobat contain 32-bit code components that the operating system can no longer execute.
Can I force Acrobat Pro XI to run on macOS 10.15?
No, Acrobat Pro XI is strictly a 32-bit application and is completely incompatible with macOS 10.15. You must either upgrade to a 64-bit version like Acrobat DC or use an alternative PDF editor.
How do I check if my Acrobat installation is 64-bit on a Mac?
Click on the Apple menu, select 'About This Mac', and click 'System Report'. Scroll down to the 'Software' section, click 'Applications', locate Adobe Acrobat in the list, and check the '64-Bit (Intel)' column to see if it says 'Yes'.
