MacOS Sierra cannot be installed on "(null)"

[bsilberman]

Is anyone else seeing this error on the OS install? The install completes successfully, but curious if this is a wider issue.

Yeah its been there since the betas and has happened to every person I know. Doesn't seem to affect anything.

How have you been installing this? I've went through beta and installed the official version with no instances of "null" errors.
