MacLoc? Here, try this. Go to Applications; Utilities; Keychain Access; Preferences. Click on “Show Status in Menu Bar”. Click on that new icon in the menu bar and you should have a “Lock Screen” command. Punch that and your screen saver will activate. You’ll have to enter your password to release the screen. (I don’t like add-ons in Macs or PC’s unless they are completely without equal.)
Tagliine? How long has that been there? Must be the missing “i” from a new iApp.
I was thinking the same about MacLoc. There’s also Option-Command-Eject (or the menu) to put the computer to sleep. Macs wake up pretty quick, so it’s only a couple seconds slower to come up than if you locked it, and you save some electricity.
