Don’t trust your co-workers? Annoyed at people messing up your files when you leave the computer for 20 seconds? Protected Screen will allow you to protect your computer from wandering hands.

Protected Screen will automatically cover up your screen with a protective cloak. A password enables you to protect your files. Make sure you remember to turn off spaces!

NOTE: Runs best on an iMac due to screen size. However, it will still fit on most screens.
