Is Adobe Acrobat Pro Compatible with 64-Bit macOS?
Question details
Users with older, perpetual licenses of Acrobat Pro need to know if their software will continue functioning on 64-bit-only macOS environments.
- Product
- Adobe Acrobat Pro
- Device & OS
- macOS 10.15 and later
- Scenario
- Upgrading a Mac to a newer operating system that drops support for 32-bit applications while relying on an older version of Acrobat Pro for PDF management.
- Observed behavior
- Older 32-bit versions like Acrobat 9 completely fail to launch, while perpetual licenses like Acrobat Pro 2017 may experience unpredictable compatibility issues without future updates.
Before upgrading your Mac to macOS Catalina (10.15) or a newer 64-bit-only operating system, verify the exact version of your current PDF software to avoid losing access to your documents.
Identify Your Acrobat Version and Upgrade Path
Determine which version of Acrobat you are currently running to understand its compatibility with 64-bit macOS environments.
Apple removed all support for 32-bit applications starting with macOS 10.15 (Catalina). This means older software must be updated or replaced.
Adobe has shifted primarily to a subscription model to keep pace with these frequent operating system architecture changes.
Open your Adobe Acrobat application on your Mac. Click on 'Acrobat' in the top menu bar and select 'About Adobe Acrobat' to see your specific release year and version.
If you are using Acrobat 9 or older, your software is 32-bit. It will not run on macOS 10.15 or later under any circumstances. You must upgrade your software.
Acrobat Pro 2017 is a perpetual license. While it may initially run on 64-bit systems, Adobe does not guarantee future upgrades for it, meaning future macOS updates could break its functionality.
Acrobat Pro DC operates on a subscription model. Because it receives continuous updates from Adobe, it maintains full compatibility with modern 64-bit macOS versions.

Frequently Asked Questions
Will Acrobat 9 work on macOS Catalina or later?
No. Acrobat 9 and other older versions are 32-bit applications. Apple completely removed support for 32-bit apps starting with macOS Catalina (10.15), meaning these older programs will not run at all.
Does Acrobat Pro 2017 support 64-bit macOS?
Acrobat Pro 2017 includes 64-bit support and works on some newer macOS versions. However, because it is a perpetual license without future feature upgrades, Adobe does not guarantee its compatibility with the absolute latest macOS releases.
Why is Adobe pushing a subscription model for macOS compatibility?
Operating systems like macOS frequently undergo significant architectural changes. A subscription model like Acrobat Pro DC allows Adobe to push continuous updates, security patches, and compatibility fixes to ensure the software keeps running smoothly on new macOS versions.
How do I check if my Mac apps are 32-bit or 64-bit?
Click the Apple logo in the top left corner, select 'About This Mac', click 'System Report', and scroll down to 'Software' > 'Applications'. Check the '64-Bit' column to see if your installed version of Acrobat says 'Yes' or 'No'.
