Here
is a way to make a login banner without using the terminal,
for all
of you mac purists. The catch is you need Developer Tools
installed.
- In
the Go menu, use Go to Folder; type in /Library/Preferences
- Locate
the file com.apple.loginwindow.plist, select it (single-click)
- In
the File menu, select Get Info, click on the triangle next
to
Ownership & Permissions
- Click
on the lock icon, change the Owner from system to yourself
(me)
- In
/Developer/Applications, open Property List Editor
- Open
/Library/Preferences/com.apple.loginwindow.plist
- Click
on the triangle next to Root
- Click
one of the items and click New Sibling
- Under
the Property List column, add the name LoginwindowText
- Leave
the class as string. Double-click in the Value area and
paste
in this text:
