Somebody just broke into my car and stole my Macbook. What's the best thing to do if I don't want the to be able to access my data? I honestly don't recall if I had a password set on login screen since I sometimes turn it off when I'm working a lot from home. I imagine if I had no password set I'm screwed, or is there anything I can do still? If I did have a password set, can they still access my data? And should I do remote erase or lock, i.e., which is safer? Thanks!
