Hi! I’d be happy to help you with deleting your profile picture on the Goodnight app. To start off, could you tell me if you’re trying to delete or just change the profile picture? Also, do you see any error messages or does the option to delete simply not appear?

Meanwhile, a common issue on macOS with apps like Goodnight is related to permissions for accessing photos. Let’s quickly check if Goodnight has the necessary permission to modify your photos:
1. Open System Preferences on your Mac.
2. Go to Security & Privacy > Privacy tab.
3. Select Photos from the left panel.
4. Make sure Goodnight is checked to have 'Read and Write' access.

If it’s unchecked, please check it, then restart the Goodnight app and try deleting your profile picture again.

If the permission seems fine and you still can’t delete it, sometimes the app interface does not have a direct "delete" option but allows you to restore the default profile picture or replace it with another one instead.

Let me know how it goes or if you can share more details about what you see when you try to delete the picture!
