And Apple Mail, Tor/ File Vault helps with that? I guess File Vault if you use it 100% of time, and log out, means those guys could never get into see anything... without your premiison, unless they were waterboarding you!
Given that FileVaulting or Un-FileVaulting a drive can take anywhere from 24 to 36 hours most people will pretty much use it 100% of the time. However, in spite of how long it took to encrypt my drive, I have not seen any noticeable slowdown in normal use. Other than not being able to use automatic logon the user experience is changed.
