Question details
The user is unable to install or run Acrobat Pro DC due to an operating system prompt requesting a system upgrade from OS X 10.9.5.

- Product
- Adobe Acrobat Pro DC
- Device & OS
- Mac OS X 10.9.5
- Scenario
- Attempting to launch or install Acrobat Pro DC on an older Mac operating system.
- Observed behavior
- The system prevents Acrobat Pro DC from running, indicating that OS X 10.9.5 is incompatible and an operating-system upgrade is required.
Click the Apple menu and select 'About This Mac' to determine your exact Mac model year, which is required to confirm whether your hardware supports upgrading to OS X 10.11 or later.
Upgrade macOS to Meet Minimum System Requirements
Upgrade your Mac operating system to OS X 10.11 or newer to fulfill the minimum software requirements for Acrobat Pro DC.
Acrobat Pro DC no longer supports Mac OS X 10.9.5. To run the software, your system must be operating on at least OS X 10.11 (El Capitan). Keep in mind that a major operating-system upgrade requires compatible hardware and is different from installing a standard software update.
Navigate to Apple's official support website to check if your specific Mac model identifier supports OS X 10.11, macOS 10.12, 10.13, or 10.14.
Open the Mac App Store and search for the latest compatible macOS version for your device, or download the OS X 10.11 installer directly from the Apple Support page.
Click 'Get' or 'Download' to retrieve the installer, then double-click the file in your Applications folder and follow the on-screen prompts to complete the system transition.
Once the Mac restarts into the new operating system, launch the Adobe Creative Cloud desktop application and install Acrobat Pro DC again.

Edit and Manage PDFs with WPS Office on Mac
If your current macOS version prevents you from running heavy PDF software, try WPS Office. Its built-in PDF toolkit provides comprehensive viewing, editing, and conversion features that are lightweight and highly efficient on macOS devices.
- 1. Download the software: Navigate to the official WPS Office website and download the Mac version installer.
- 2. Install on your Mac: Open the downloaded .dmg file and drag the WPS Office icon into your Applications folder.
- 3. Open the PDF tool: Launch WPS Office from your Launchpad, click on 'PDF' in the sidebar, and open your existing PDF file.
- 4. Edit your document: Use the intuitive top ribbon menu to edit text, insert images, add signatures, or convert the PDF to other formats.

Frequently Asked Questions
What is the difference between a macOS update and a macOS upgrade?
An update generally contains free revisions, security patches, or bug fixes for your current operating system version (e.g., updating from 10.9.4 to 10.9.5). An upgrade is a major transition to a completely new version of the operating system, such as moving from OS X 10.9 to OS X 10.11.
Which macOS versions are officially supported by Acrobat Pro DC?
Acrobat Pro DC requires at least Mac OS X 10.11. Fully supported releases include Mac OS X 10.11, macOS 10.12, macOS 10.13, and macOS 10.14 or later, depending on the specific release build you are installing.
Why can't I upgrade my Mac to OS X 10.11?
Your Mac computer may have specific hardware limitations. Older Mac models eventually stop receiving support for newer macOS versions due to incompatible processors, insufficient RAM, or outdated graphics capabilities.
