Unibeast 5.1.0 hangs

I've tried this using several different USB drives (at least 8GB) and on a Hackintosh running 10.9.5 and a Macbook Pro on 10.10.3. It gets almost to the end, but then the hang occurs. At the point it appears Unibeast starts to spin on something as the fan on my MBP goes much faster.

I've tried this off and on over the last several weeks, but I get the same result. Any ideas on what's wrong?

The following is from /var/logs/install.log:

UniBeast is failing when it is trying to install the smbios on the target disk.

Not sure why, will look into it further.
