SO... someone recently used my MacBook Pro (13-inch, Mid 2012laptop, OS X El Capitan) after they left I noticed my 'BLUETOOTH APP" was enabled and running. Is there a way to see if any of my files were transferred or copied? I have a lot of original work-writings, music, etc on my laptop. I should of logged them in as a user but I didn't. I know, don't have to say it.
