10.4: Work around a non-functional screensaver lock System 10.4
Several people on the Apple forums have reported that the 'Lock Screen' function of Keychain Access doesn't work, despite having "Require password to wake this computer from sleep or screensaver" toggled on in the Security System Preferences panel.

I discovered that if I log out and then log in again, the screensaver lock works as expected, and remains functional until the next restart. FYI, my machine is started from cold every day, and Automatic Login is disabled. This abberant behaviour happens on my Quicksilver Dual 800, but not on my old and venerable B&W G3, both running 10.4.7.

Of course, YMMV ... hope this helps a few folks.

applejack AUTO reboot

I had to reset PRAM on my MacBookPro (2GHz). That fixed it. I was going mad trying to figure out what happened. Do this:

1. Shut the computer off.

2. Restart holding the Option-Command-R-P keys down, wait for three "bongs" and release keys.

That should do it, when it comes back up you should be able to lock your screen again.

10.4: Work around a non-functional screensaver lock

I experienced the same problem and after failing to find any lasting fix, I searched for other solutions and found one: 10.3: Use fast user switching from the Terminal. While this was written for 10.3, 10.4 introduced Automator. So I did the following:

  1. Created a workflow in Automator using the Run Shell Script action, pasting in the shell script written by makaio
  2. Saved the workflow as a plugin for the finder which saves it in ~/Library/Workflows/Applications/Finder/loginscreen.workflow
  3. Using Quicksilver, I created a mouse trigger which ran the workflow when I click twice on a screen corner
Now, whenever I leave the machine, I simply double click on a corner invoking the Quicksilver trigger which runs the Automator workflow which excutes a shell script which rotates the cube and brings up the login screen. I have the display set to sleep in 30 so energy consumption is reduced. Because the login screen uses no CPU, I can be running processes in the background and my computer can be backed up.
