1. Navigate to the settings on your mobile device.
2. Look for the 'Apps' or 'Manage apps' section in your settings. This may vary slightly depending on your device.
3. Search for and select 'CapCut' from the list of apps.
4. You should see an option called 'Storage' or 'App Storage'. Click on it.
5. You should now see two options: 'Clear data' and 'Clear cache'. Click on 'Clear cache'.
6. A prompt might appear. Confirm that you wish to clear the cache.
7. The cache for CapCut on your device should now be cleared.

Remember, clearing cache will not delete any important data like your personal videos or edits. It only removes temporary files that might be causing issues with the app.

Unfortunately, as of now, the CapCut app does not provide an explicit way to clear cache on a Mac or PC. The app is primarily designed for mobile devices and may not have the same range of features on a desktop or laptop.

If you're experiencing issues with the app on your MacBook or a different device running macOS, you might need to try troubleshooting other potential problems or reinstall the software. Here's how you can reinstall the software:

1. Locate CapCut on your Mac (it might be in the "Applications" folder)
2. Move the CapCut app to the Trashbin and empty the Trash.
3. Reinstall the software from CapCut's website or your preferred software source.

Remember, before uninstalling the software, make sure to backup all your important projects as these may be deleted when you uninstall the software. If your issue remains unresolved, it might be worth reaching out to CapCut's support for more specific guidance.
