I have tried different Linux flavors through Live Disks and I do like using that as one of privacy measures. I did some looking into obtaining Live Disk of Mac OS X but could not find one. Some people say it is impossible to make one but is it?
If any part of the OS or the apps it's running requires write access, it may crash or refuse to work. I understand that so if neither CD nor DVD(DL) is an option what about USB flash drive?
