Here’s a little personalization you can do for your Mac OS X Leopard. If your name (nickname or just in case you named your mac something else) did not appear on the menubar, here’s how you can get it display on the right hand corner.
Click the Apple logo, go to System Preferences.
Click Account, click the icon at the bottom to unlock so you can change the settings.
Click Login Options, check “Enable fast user switching” and select “View as: Name“
Voila, your name should now appear on the menubar, right hand corner.
