Core Sync is a syncing component of the Adobe Creative Cloud (CC) suite. Plagued with high CPU usage, Core Sync slows your Mac, but that’s not the worst part about it—the app tends to stick around after uninstalling Adobe, throwing file access prompts every now and then.

Authorizing access won’t jeopardize your privacy, though the annoying message has intimidated some people. Removing Core Sync with the standard uninstallation method has proved very difficult. Fortunately, you can manually kill its processes and stop them from reloading in the future. We’ve got the instructions, so let’s get to work, shall we?

What Is Core Sync on Your Mac?

Adobe Content Synchronizer, or Core Sync, is automatically installed as part of the Adobe suite. Adobe’s Creative Cloud installer adds Core Sync to your login items to ensure it automatically launches when you start your Mac or log out and back in. It also installs a macOS extension for synchronization status of Adobe cloud files in the Finder interface.

Lastly, Core Sync creates background processes that sync your files, Adobe fonts, CC libraries, and other documents. These things also eat up CPU time and hog the RAM, causing your MacBook to overheat and reduce its battery lifespan.
