Open Activity Monitor from the Applications > Utilities folder.
Select launchservicesd and click the x button.

Close unnecessary apps

One possible reason for the high CPU or memory usage of launchservicesd is that too many applications are running at the same time. It's advisable to close those you don't need to release the resources.

Update your apps

Launchservicesd may demand excessive CPU or memory if certain apps on your Mac are having issues. If you notice the resource usage rises after opening a specific app, you can update this app or uninstall it if it's unnecessary. To figure out the culprit, you can also check the logs or reports in the Console app.

If you're uncertain which one is at fault, update all your apps.

Boot into Safe Mode

If launchservicesd is still acting up, try booting your Mac into Safe Mode and then reboot normally to see if the issue remains. macOS Safe Mode loads only the essential parts your Mac needs to work. It can help identify if third-party software is causing the issue, clear system caches, and verify your startup disk.
