I have two general questions: 1. How do I lock a folder and all of its contents and subfolders so that no program can alter them? I have discovered the "lock" checkbox in Get Info, but it doesn't lock subfolders, which is a deal-breaker. 2. Right out of the box, my MacBook Pro had 43 processes running after startup, including activity monitor. Now it has 48. I have not looked at my screenshots and identified the 5 newbies specifically. If I did that, and I deemed them unnecessary, how could I block those processes? Thanks.
