I'm trying to get an encrypted dual-boot running and ran into some issues.

My setup is thus: half the hard drive is an encrypted OSX partition, and I would like the other half to be encrypted Kali+swap and what have you. All the instructions I can find are either for just encrypting the home folder or for encryption during install, which doesn't seem to let me aim at a particular partition. I have Kali installed already unencrypted, but I can re-install again if necessary.

I don't know if I should be asking this here or not but my second issue is that Kali won't detect/connect to 5GHz bands. OSX does with no problem, so I know it's most likely a driver issue since the hardware clearly works.

Thanks in advance!
