If you're experiencing stuck notifications on your Mac, there are several solutions you can try to resolve the issue.

One recommended method is to use the Activity Monitor to quit and restart the Notification Center. You can do this by searching for "Notification Center" in the Activity Monitor and clicking the red "Quit" button. Restarting the Notification Center often clears persistent notifications. For detailed guidance on this method, you can refer to the article on OSX Daily.

If you prefer a simpler approach, try opening the Notification Center and hovering over the notification. This action may cause the options to reappear, allowing you to dismiss it. Users on Reddit have reported this method as effective for getting rid of stubborn notifications. You can read more about it here.

In cases where the Notification Center is completely unresponsive, there are additional steps you can take, such as restarting your Mac, uninstalling third-party menu apps, or removing login items. For more serious issues related to Notification Center freezing, you can check the guide on iBoysoft.

For basic management of notifications, consider using the "Do Not Disturb" feature to temporarily pause notifications or disabling unwanted app notifications entirely. More detailed instructions can be found on MacSecurity.net.

Finally, if none of these solutions work, you might want to explore discussions on Apple Community or Ask Different, where users share their experiences with similar issues and solutions. For instance, a discussion on stuck blank notification banners can be found here.
