So I have been searching google like crazy. I know when I had Windows I could hide certain files that I didn't want anyone to find if my computer was taken unless they knew which folder I had it in and how to reveal it and the password to unlock it to view it. I can't seem to find a way to do this with my Mac outside of having to download a free app or buy one to pw protect it. Does anyone know a way to hide / pw protect a file?
