Just a quick update on something I found for my precious Aluminum MacBook in order to get a beloved Windows function over to my Mac.

LockTight is a Preference Pane for Mac OS X that enables you to press a specific Key-Combination in order to lock your Mac so it can only be reactivated with your password.
Previously to that I have been using "Fast User Switching" to get to the Login-Window quickly but there were 2 major problems to that.

1. Network Connections are interrupted. So no Background Downloading while you’re away.
2. iTunes Music stops playing.

With LockTight I have worked that out and I like its behavior very much since the Screen doesn’t just go black but starts displaying the screensaver of your choice.
