Virtual Memory Configuration – Remons TechNotes

Mac Pro Early Nehalem Configuring and optimizing.. Desktop Hard Drives Performance and use.. 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?

No mention of it being encrypted or it being there are all, maybe swap is disabled somehow? Do i really need it if it is disabled? Good suggestion to use the Apple Feedback, will do that and let you know what they said and so others can use this thread as a reference. While i'm at it i'll also ask more details about the secure empty trash, maybe they know more about that.
