Due to the Core Sync background process, some Mac users have issues with their MacOS having high CPU usage.

This process can slow down any machine, and the only way to solve this issue is to turn it off.

The Core Sync process indicates that the Adobe Creative Cloud is up and running in the background, which eventually uses up to 100% of the CPU resources and causes some machines to crack up, have loud noise, or have unwanted electricity consumption.

So, it is up to us to find a solution to fix this. Therefore, stay here if you want to learn how to turn it off and disable the Core Sync process on your Mac.

What is Core Sync?

Basically, the Core Sync is a component of the Creative Cloud desktop app and its installation. In addition, it is a background process that happens between your machine and the Creative Cloud, and it is responsible for syncing all the files in the Creative Cloud Files folder on your computer with Adobe servers. Sometimes it can use up to 100% of the CPU and will automatically slow down the overall performance of your computer.
