I just recently tried to install Truecrypt, which is by far my favorite HD encryption program. Unfortunately they only have a 32-bit version available, so my 2011 MBA with Lion can't run it. Is there any way to work around this? If not I was wondering if anyone has any good alternative programs to Truecrypt?? Preferably open-source with AES-256 encryption. This is my first mac and true crypt is a must for me so any help would be greatly appreciated!!
