Hi there, Apologies if this has been addressed before, I searched but couldn't find anything. I installed the El Capitan GM last week through the public beta program and noticed the "Set Lock Message..." option in Security & Privacy for the first time (although after looking into it some more, it doesn't seem to be a new feature). Since I wanted to see what it did, I put in the message "Test" and logged out. It came up with a message saying "Test" on the log-in screen. Content, I then removed the message. However when I boot up the "Test" message remains. It's only there on the initial log-in screen (not when I log-out to the lock screen, after already starting up). I've tried changing it,e.g. to "Test 2", and it shows up when I log out as "Test 2", but remains as "Test" when I restart my computer. (Hopefully that all makes sense) Is there any way to get rid of the message? Thanks in advance Edit: I think it's maybe FileVault that was causing the issue. I have selected to turn it off, and after restarting the message is no longer there. My hard drive is still decrypting, so will need to wait until it finishes (about 2 hours) before I can test it further to see if it has removed the message.
