I am inclined to run Tails through a virtual machine so that I could chain two VPNs. One running through the host Mac osx and one more running from inside the virtual machine that's running Tails.However on Tails website, it says that host operating systems likely uses swapping which copies part of the RAM to the hard drive. Is there a command or program that prevents swapping on Mac osx?
How to prevent swapping on Mac OS X?
osx;swap
