But does any printer file/data save cause its on the new MacBook retina? it only boots through EPI boot mode, Is this a bad thing? will it be storing data hidden somewhere in my hard drive? Are USB's alright to use for Ubuntu live OS too? Like could it save anything? And should I just use the bitaddress from 2 months ago and make encrypted paper wallets?? still alright?? or should I just download the  new version of bitaddress? Thanks.
