Restarting login window


Forum|alt.badge.img+20

Hello Everyone,

I am drawing a blank and would like some guidance.

We have a special branded login window background and it works great. However, when a computer receives the 10.14.6 update from Apple, this login window file is reset back to Apple's default.

If I restart the computer, this will fix the problem. Is there a way to restart the login window so a restart isn't needed? I hate to kick off people from their computers to apply this "fix."

On this topic, is there a way to "lock" this file so it can't be replaced by the updater? I believe I tried this years ago but without much success as Apple's installer just blows past this.

Your thoughts and ideas are most welcome! Thank you!

Never mind, I found something way simpler than I expected. Simply sending a killall loginwindow command to the computer has the desired effect.

lock the background file or lock the loginwindow file? If it's part of /System you can't change it without disabling SIP.
