Someone told me that I can put a passwordon a file or folder in mac osx without getting an external program. Does anyone have a link to where I would find how to do this, or does anyone know how?
However you CAN make a password-protected 128bit encrypted disk image to store your data.
Use the Mac Help to find out how (search for encrypted disk image).
Well, your best bet would be to make a password protected disk image, but if you are feeling like an application check out Waterfall Software's Wallet. I love that app! Google it.
