TrueCrypt 5.0 for Mac ...Finally, but bring some bug spray.

Truecrypt 5.0 for the mac has been released. I encountered an issue with permissions on the default install under leopard/intel. If you try to run it from finder as a normal user it spits out an "unsupported architecture" error. A quick work around is to set the binary to setuid:

sudo chmod u+s /Applications/TrueCrypt.app/Contents/MacOS/TrueCrypt

I'm not sure how to work in the Leopard privilege controls (still researching, they may fix it first) and I can make no guarantee that this is a "secure" means of running the software. i.e. if there are vulnerabilities in the TrueCrypt binary one could exploit the fact that it is setuid and take control of the system...

You would need to be local to the machine to do that.

The Windows XP/Vista full disk encryption works like a charm so far. Easy to use in a single partition/boot configuration. I have not used it under multi-boot or along side grub/lilo. Happy encrypting...

Also: checkout http://www.wilderssecurity.com/showthread.php?p=1177223 since the TrueCrypt forums seem to be down ...like forever. There are some bugs in 5.0, maybe the dev team should have put out a beta for testing and while they were at it, fix their forums...

UPDATE: (2-8-8): Forums are back online. Thanks guys.
