Change the sleep icon in login window (loginwindow.app) I would like to change the sleep icon in the login window. I've found loginwindow.app (/System/Library/CoreServices/loginwindow.app) and replaced Sleep.tiff with the desired image with identical file dpi and size wise (yes that is the superhot logo). I then ran sudo killall loginwindow, thinking that I would relaunch the app and it would use the new icon. Instead, it logged me out and didn't use the new icon. Is there any way to replace this icon?  ^when it logged me out
I believe that this can be changed in /System/Library/PrivateFrameworks/LoginUIKit.framework/Versions/Current/Frameworks/LoginUICore.framework/Resources/, I’ll post if it works when I change it there

I got the correct location from here
