I would like to delete cookies for a specific website.
When I open preference -> privacy -> manage website data, the window is just showing "loading website" data for 23 hours..
I tried the method from Website Data Loads Slowly - Apple Community.
It didn't work

Welcome Yong-Bin,
Sounds like you have issues clearing the cookies from Safari on your iMac. We'll do our best to assist with this.
Have you had a chance to try deleting this in safe mode yet? If not, we'd suggest attempting this, as it will help us to isolate the behavior further: How to use safe mode on your Mac - Apple Support
How to use safe mode
Determine whether you're using a Mac with Apple silicon, then follow the appropriate steps:
Apple silicon
1. Shut down your Mac.
2. Turn on your Mac and continue to press and hold the power button until you see the startup options window.
3. Select your startup disk, then press and hold the Shift key while clicking “Continue in Safe Mode.”
4. Log in to your Mac. You might be asked to log in again.
Intel processor
1. Turn on or restart your Mac, then immediately press and hold the Shift key as your Mac starts up.
2. Release the key when you see the login window, then log in to your Mac.
3. You might be asked to log in again. On either the first or second login window, you should see ”Safe Boot” in the upper-right corner of the window.
If the issue continues in safe mode
If the issue continues while in safe mode, or your Mac restarts several times and then shuts down while starting up in safe mode, you should reinstall macOS and make sure that your Apple software and third-party apps are up to date.
If the issue doesn't continue in safe mode
If the issue doesn't continue while in safe mode, leave safe mode by restarting your Mac normally. Then test for the issue again. The issue might be resolved.
If the issue returns after leaving safe mode, startup items are probably at fault. Apps can install such items in numerous places, and they aren't always easy to find or recognize. For that reason, you should first make sure that you've installed any available updates for your Apple software and third-party apps.
If updating your software doesn't help, try any of these solutions:
- Test your login items.
- To learn whether software in your user account is causing the issue, set up a new user account, then log in to it and try to reproduce the issue in that account.
- Unplug all accessories from your Mac, including printers, drives, USB hubs, and other nonessential devices. You could have an issue with one or more of those devices or their cables.
- Reinstall macOS.
If you still need help, please contact Apple Support.

Some features might not work in safe mode, such as movie playback in DVD Player, video capture, file sharing, Wi-Fi, some accessibility features, some audio devices, and some devices that connect via USB, Thunderbolt, or FireWire. Accelerated graphics are disabled, which could cause blinking or distortion onscreen during startup.
If the issue continues to occur in safe mode, do you have issues searching for anything specific in Manage Website Data? Are you able to search there?
Let us know how it goes and we'll take it from there, take care.
