Deleting Profile Picture in System Preferences
How do I delete the profile picture that shows up in System Preferences? I clicked one of the default pictures when setting up Mac OS Big Sur, but I realized that I would rather just have no image.
I ran this command in Terminal, which removed it from Users and Groups and the login screen:
sudo dscl . delete /Users/USERNAME jpegphoto
I also deleted the picture from Contacts and iCloud.com, but it hasn't removed it from System Preferences or the at the bottom left corner of the Mac App Store.
