Fix Acrobat XI Future macOS Compatibility Warning
Question details
The user encounters a warning in macOS stating that Adobe Acrobat XI will not be compatible with future operating system versions.
- Product
- Adobe Acrobat XI
- Device & OS
- macOS
- Scenario
- Running or attempting to launch Adobe Acrobat XI on a modern macOS environment.
- Observed behavior
- macOS displays a warning dialog indicating that the application needs to be updated because it is a 32-bit application and will not work with future OS versions.
Before taking action, verify your current macOS version in 'About This Mac' and ensure your PDF files are saved to a secure location.
Upgrade to Adobe Acrobat Pro DC or a Supported Release
Because Acrobat XI is a 32-bit application, you must switch to a 64-bit version of Adobe Acrobat to run it on modern macOS systems.
Apple dropped support for 32-bit applications starting with macOS Catalina (10.15). Acrobat XI is strictly a 32-bit application, which is why macOS displays the compatibility warning.
Adobe cannot automatically upgrade Acrobat XI to Acrobat DC. You will need to manually transition to a newer 64-bit perpetual license or a subscription plan.
Visit the official Adobe website and review the available Acrobat DC subscription plans or perpetual releases.
Select the plan that fits your needs, complete the purchase, and download the 64-bit installer for macOS.
Run the downloaded installer, follow the on-screen prompts, and sign in with your Adobe ID to activate the new version.
Delay the macOS Upgrade (Temporary Workaround)
If you absolutely must continue using Acrobat XI, you can postpone updating your Mac to macOS Catalina or later.
Edit PDFs Smoothly on Modern macOS with WPS Office
If you are unable to use Acrobat XI due to macOS 32-bit restrictions and want to avoid expensive subscription fees, use WPS Office. It includes a native 64-bit PDF editor that runs perfectly on macOS Catalina, Big Sur, Monterey, and Sonoma.
- 1. Download WPS Office: Visit the WPS Office website and download the macOS version.
- 2. Install the software: Open the downloaded package and drag WPS Office into your Applications folder.
- 3. Open your PDF files: Launch WPS Office and open your existing PDF documents directly without compatibility warnings.
- 4. Use PDF tools: Navigate to the 'PDF' tab to view, edit, annotate, or convert your documents easily.
