- Product
- Adobe Acrobat
- Device & OS
- macOS
- Scenario
- Using Adobe Acrobat or Creative Cloud applications with background cloud and collaboration processes active.

- Multiple AcroCEF Helper processes run simultaneously and consume extremely high CPU on Mac devices, leading to app crashes and unresponsiveness, even after reinstalling macOS and replacing hardware.
Save all open documents and ensure you have an active internet connection before modifying or quitting any background cloud synchronization processes.
Isolate Background Processes and Update Software
Updating macOS and Adobe applications while temporarily disabling cloud features helps identify and resolve the high CPU usage.
AcroCEF Helper is tied to Adobe's cloud services, sign-in architecture, and collaboration features. High CPU consumption often occurs due to sync glitches or outdated software versions.
Open the Creative Cloud desktop app and install the latest available updates for Adobe Acrobat and all other Adobe applications. Ensure your macOS is also up to date via System Settings.
Open Adobe Acrobat, sign out of your account, and temporarily disable any document collaboration or cloud syncing features.
Open the Activity Monitor on your Mac. Locate Creative Cloud background processes and 'AcroCEF Helper', select them, and click the 'Stop' (X) button to force quit and see if system performance stabilizes.
Collect Crash Logs for Adobe Support
If the issue persists across multiple devices despite system reinstalls, gathering logs for Adobe Support is the most effective approach.
Try WPS Office for a Lightweight Document Experience
If background processes from other applications continue to drain your Mac's battery and CPU, consider switching to WPS Office. It includes a powerful, built-in PDF reader and editor that is lightweight, highly optimized for macOS, and free to download.
Frequently Asked Questions
