In-Depth Information
rich-text files will retain formatting, such as colors or bold text. Make
sure you use systemwide fonts rather than any fonts installed specifically
for your user account (this won't be an issue if you've never manually
installed fonts, but be careful not to use any Microsoft Office fonts like
Candara or Cambria).
2.
Save the file to the desktop, giving it the name
POLICYBANNER.RTF
or
POLICYBANNER.TXT
,
depending on whether it's rich-text format or plain text.
3.
Open a Terminal window (open Finder, select the Applications list, and
then in the list of applications double-click Terminal within the
UTILITIES
folder), and then type the following, typing your password when prompted:
SUDO MKDIR /LIBRARY/SECURITY
Close the Terminal window.
4.
Open a Finder window, and hit
SHIFT
+
COMMAND
+
G
. In the dialog box that
appears, type
/LIBRARY/SECURITY
.
5.
Click and drag the PolicyBanner file you created to the Finder window. A
dialog box will appear, asking you to authenticate, which you'll need to
do, so hit the relevant button and type your login password when
prompted.
From now on, you'll see the document appear in a window when you log in.
Clicking the Accept button will clear it, after which you'll see the standard
login options.
If the Mac's disk is encrypted with FileVault, the user will see the document
when they boot, after they've typed their username but before the desktop
appears. In fact, they won't be blocked from using the computer until they
click the Accept button.
Removing the Logon Message
To permanently eradicate this new addition to the login screen, again just
browse to
/LIBRARY/SECURITY
and move the
POLICYBANNER.RTF
or
POLICYBANNER.TXT
file to the
trash. You'll be asked to authenticate again.
