Prey worked perfectly to get the cops to go to the thief's house! My Macbook Air OS X Lion is safe now. All the programs I installed are still there, and my folders are still exactly in the same positions. Even the subfolder in a folder I named my ebooks is still in the same position at the bottom of the finder window. The folders are untouched but anything that is a file is gone. It doesnt seem to be a reformat because my programs that are meant to run (BOINC) in the background still start up and the folders would be gone. How is this possible? Is it possibly a feature of Prey that I have misread? I cannot find it. Even my Dropbox was made empty and my wallpaper was blank because the image file was gone. Desktop empty too.
