Before proceeding, check your Mac's model year in the 'About This Mac' menu to determine if your hardware is eligible for a newer macOS upgrade.
Upgrade OS X El Capitan to a Supported macOS Version
The current release of Adobe Acrobat DC requires a newer operating system. Upgrading your macOS is the official and most secure way to fix this compatibility issue.
Apple ended support for OS X 10.11 (El Capitan) in 2018, and software developers like Adobe have subsequently updated their system requirements to only support newer operating systems. To run the latest Adobe Acrobat DC, you must update your Mac.
Click the Apple menu in the top-left corner of your screen and select 'About This Mac' to confirm you are running OS X 10.11.6.
Click the 'Software Update' button or open the App Store to search for the latest macOS version available for your device.
Follow the on-screen prompts to download and install a newer macOS version, such as macOS Catalina, Big Sur, or later.
Once the macOS upgrade is complete, go back to the Adobe website and attempt to download and install Acrobat DC again.
Install a Legacy Version of Adobe Acrobat
If you cannot upgrade your Mac hardware past OS X 10.11.6, you will need to find and install an older, legacy version of Acrobat that still supports El Capitan.
Use WPS Office for Fast and Compatible PDF Editing
If your Mac operating system is too old for the latest Adobe Acrobat DC, WPS Office provides a lightweight, highly compatible, and free alternative. It allows you to seamlessly view, edit, and manage PDF files without demanding heavy system requirements.
