I have my Mac configured to require a password when it goes to sleep or when the screen saver comes on. When I wake it up I'm presented with a login box and the screen behind it is flat black. I would like to change or add a background to this unlock screen but I'm not sure if it's possible. I'm aware of how to customize the background of the OS X startup login screen.

There is no resource in
/System/Library/Frameworks/ScreenSaver.framework
to change.There is no mention of a wallpaper path in
/Library/Preferences/com.apple.screensaver.plist
,~/Library/Preferences/com.apple.screensaver.plist
or~/Library/Preferences/ByHost/com.apple.screensaver.MachineID.plist
.Secrets.prefpane doesn't have a setting.
Using
fs_usage
to see all disk paths accessed during locking and unlocking the machine viaCtrl-Shift-Eject
yielded no unexpected disk accesses: No default wallpaper path, and all accessedplist
preferences files (predominantly all variants of.GlobalPreferences
, and surprisinglycom.apple.loginwindow
) mention any file path.I conclude: It's very likely impossible.
