Question details

- Product
- Adobe Acrobat DC
- Device & OS
- macOS
- Scenario
- Setting up a professional prepress workflow by adding specialized third-party toolkits to the Acrobat DC environment.
- Observed behavior
- The user wants the plug-ins to be successfully installed, activated, and visible within the Acrobat DC application interface.
Ensure that your macOS and Adobe Acrobat DC are fully updated, and verify that you have your valid license keys and the official installer files from Callas and Enfocus downloaded.
Use the Official Developer Installers
The most reliable method to integrate prepress tools is using the dedicated installer packages provided by Callas and Enfocus, which automatically route the required files into the Acrobat directory.
Third-party plug-ins must securely hook into Acrobat's architecture. Bypassing the official installers by manually moving files can lead to permission issues or missing tools on macOS.
Navigate to the official Callas or Enfocus websites, log into your user account, and download the latest macOS installer package for your licensed plug-in.
Quit Adobe Acrobat DC completely. Ensure it is not running in the background to prevent file lock errors during installation.
Double-click the downloaded .pkg or .dmg file and follow the on-screen prompts. Allow the installer to automatically locate your Acrobat DC Plug-ins folder.
Relaunch Adobe Acrobat DC and navigate to the 'Tools' or 'Plug-ins' menu at the top of the interface to verify that the new toolboxes are visible and ready for use.

Contact Plugin Support for Missing Tools
If the installed plugins do not appear in Acrobat DC after a standard installation, developer assistance is required for manual routing or activation troubleshooting.
Try WPS Office for Your Everyday PDF Editing Needs
While advanced prepress workflows require specialized Acrobat plug-ins like PitStop, WPS Office provides a powerful, lightweight, and free alternative for all your standard PDF editing, converting, and document management needs. It offers an intuitive interface and excellent format compatibility.

Frequently Asked Questions
Why are my newly installed plug-ins not showing up in Acrobat DC on macOS?
This usually happens if the plug-in version is incompatible with your current Acrobat DC update, or if macOS security settings prevented the installer from placing the plug-in files in the correct Adobe root folder. Verify compatibility on the developer's website and check your Mac's Privacy & Security settings.
Can I manually install the Enfocus PitStop plugin files?
Yes, if the installer fails, you can often manually copy the required `.acroplugin` files into the Acrobat Plug-ins folder (located within the Adobe Acrobat application package contents on macOS). However, using the official installer is heavily recommended to ensure proper file permissions.
Are Callas Toolbox and Enfocus PitStop free to use?
No, both Callas Toolbox and Enfocus PitStop are premium, professional-grade prepress tools. They require valid commercial licenses and activation keys from their respective developers to function within Acrobat DC.
