The Adobe Creative Cloud is used to download, update and track every Adobe application on your computer, as well as the ones you haven’t purchased. It is also responsible for managing your Adobe user data and storing these data on your local storage. This is where the CoreSync comes into play.
CoreSync works in the background and acts as a bridge between your system and the Adobe server. It syncs data files to and fro between your computer and the cloud. However, when these files are larger in size, CoreSync can end up taking a lot more CPU than intended, sometimes even skyrocketing it up to 100%.
Other than this, there are several reasons that might influence CoreSync to use a high CPU percentage. These include:
Corrupted caches
If the cache files associated with CoreSync become corrupted, it can result in high CPU usage.
Outdated app
Running an outdated version of the Adobe Creative Cloud application may cause compatibility issues and result in increased CPU usage.
Location glitch
In some cases, CoreSync may encounter location-related glitches, leading to high CPU usage.
Malware attacks
Malicious software or malware can interfere with CoreSync’s operation and cause it to consume excessive CPU resources.
How to Monitor Your CPU Usage?
macOS provides users with the Activity Monitor tool to monitor running processes and the allocation of system resources. This tool comes preinstalled on your computer and can be accessed directly from the desktop screen. To monitor CPU usage:
- Press Command + Space to open the Spotlight search.
- Type and enter “Activity Monitor”.
- Navigate to the CPU tab.
- Here, you can view how much CPU CoreSync is currently using.
How to Fix the High CPU Usage of CoreSync?
Whenever CoreSync’s CPU usage exceeds the normal threshold, you can take quick actions to reduce it. Here are some effective methods to fix the high CPU usage issue:
Restart Your Computer
Restarting your computer is a simple and short-term solution that clears the system memory and reallocates system resources. This can help bring down the CPU usage of CoreSync temporarily.
End the CoreSync Process
Using the Activity Monitor, you can manually force the CoreSync process to shut down. This will significantly reduce the CPU percentage and restore normal operation. To end the CoreSync process:
- Press Command + Space to open the Spotlight search.
- Type and enter “Activity Monitor”.
- Navigate to the CPU tab.
- In the search field at the top right corner of the window, type “Core Sync”.
- From the Process Name column, select Core Sync and click the “x” icon to force quit the process.
Disable the CoreSync Extensions
Disabling the CoreSync extensions can help alleviate high CPU usage. You can do this through your Mac’s System Preferences:
- Click on the Apple menu.
- Select “System Preferences”.
- Proceed to “Extensions”.
- Select “Added Extension” from the sidebar.
- Uncheck “Core Sync Finder Extension”.
- From the left panel, select “Finder Extensions”.
- Uncheck the option box for “Core Sync Helper”.
Delete the CoreSync Cache Files
Deleting the CoreSync cache files stored on your computer can resolve stability and corruption issues that may contribute to high CPU usage. Follow these steps to delete the cache files:
- Open Adobe Creative Cloud.
- Click on your user profile icon and go to “Preferences”.
- Select “Syncing” from the sidebar.
- Pause syncing.
- End the CoreSync process from the Activity Monitor.
- Close all open windows and go to Finder.
- Hold the Option key and click “Go” on the menu bar.
- Go to “Library”.
- Navigate to “Application Support” > “Adobe” and delete the “CoreSync” folder.
- Again, from the “Library” folder, navigate to “Preferences” > “Adobe” > “CoreSync” and delete “cache_config.xml”.
- Restart your computer.
- Open Adobe Creative Cloud and resume syncing.
Update the Creative Cloud Application
If other methods fail to resolve the high CPU usage issue, try updating the Creative Cloud application. Updating to the latest version can fix bugs and glitches that may be causing the problem. To update the application:
- Open Adobe Creative Cloud.
- Select “Updates” from the left sidebar.
- Click on “Check for updates”.
- If a Creative Cloud update is available, click on “Update” to update the application. You can also update all your Adobe applications from this window.
Is CoreSync a Virus?
Although the CoreSync process consumes a significant amount of CPU and may not be visible in the foreground, it is not a virus. CoreSync is a legitimate process associated with the Adobe Creative Cloud application. However, if you are using an unauthorized or pirated version of the Creative Cloud application, there is a possibility that the software’s processes, including CoreSync, could operate against you. To ensure the safety of your system, always use a genuine and licensed product from Adobe.
