Users need to transition from a 32-bit version of Adobe Acrobat Pro to a 64-bit version to ensure the software continues functioning on newer Mac operating systems.

- Product
- Adobe Acrobat Pro
- Device & OS
- Mac
- Scenario
- Upgrading a legacy 32-bit PDF application to a 64-bit architecture to meet the strict system requirements of recent macOS updates.
- Observed behavior
- The Mac displays a 32-bit warning, and older standalone versions of Adobe Acrobat Pro completely stop working after updating to macOS Catalina (10.15) or later.
Before attempting any software removal or operating system updates, verify your Adobe licensing details and back up all critical PDF files.
Upgrade to a 64-Bit Version of Adobe Acrobat
Install a current 64-bit release, such as Adobe Acrobat Pro DC, to restore functionality on modern macOS environments.
Starting with macOS Catalina, Apple entirely removed support for 32-bit applications. To continue editing and managing PDFs natively on your Mac, you must migrate to a supported 64-bit version of Acrobat.
Visit the official Adobe website to ensure your specific Mac model and current macOS version meet the requirements for Acrobat Pro DC.
Navigate to the Applications folder in Finder, locate your outdated Acrobat Pro installation, and run the official uninstaller tool to safely remove the software components.
Log in to your Adobe account, download the 64-bit Acrobat Pro DC installer package, launch the setup file, and follow the on-screen prompts to complete the installation.
Delay Your macOS Upgrade
If you rely on your standalone 32-bit Adobe Acrobat Pro and cannot afford a subscription upgrade, you can pause your operating system updates.
Edit and Manage PDFs on Mac with WPS Office
If upgrading to a 64-bit Adobe subscription is too costly, WPS Office provides a powerful, native 64-bit PDF editor for Mac. It allows you to easily view, edit, and convert PDF documents without compatibility issues on newer macOS versions.
- 1. Download WPS Office: Get the free WPS Office installer for Mac directly from the official website.
- 2. Open the PDF tool: Launch the application and select the 'PDF' tab from the home screen.
- 3. Edit your documents: Open your existing PDF files and use the intuitive toolbar to edit text, add annotations, or convert to other formats.

Frequently Asked Questions
Why am I getting a 32-bit warning for Adobe Acrobat on my Mac?
Apple discontinued support for the 32-bit app architecture starting with macOS Catalina. The warning indicates that your current older version of Acrobat is 32-bit and will not be able to run on any newer macOS version.
Will my older standalone Adobe Acrobat Pro work on a brand-new MacBook?
No. Most new MacBooks come pre-installed with newer macOS versions that exclusively support 64-bit applications. Your older standalone 32-bit Acrobat Pro will not run on these newer machines.
Is Adobe Acrobat Pro 2017 a viable 64-bit option?
While Acrobat Pro 2017 may function on some systems, Adobe has heavily limited its compatibility and future update path for newer macOS versions. Upgrading to Acrobat Pro DC or switching to an alternative 64-bit PDF editor is recommended for long-term stability.
