How can i enable secure virtual memory
When i checked About this Mac > More info > System Report and looked under Software i noticed my "Secure Virtual Memory" showed "Disabled". Now i am not particularly worried someone will haul an anchored down Mac Pro out of my home anytime soon but still, this would leave my SWAP file unsecured and possibly vulnerable for someone that has physical access to my Mac correct? My question is, how do i enable it in case i find the same to be the case on my MacBook Air, where i definitely do want it enabled?
Second question, unrelated, the Secure Empty Trash, how does it securely erase the data? A one pass, three pass or seven pass?
Thanks,
Jay
