If we can provide a patch (a pull request), it can be used by Homebrew to make working juju 2.0.0

Per bug 1629444 this was fixed. Either the commit as bad, or Juju wasn't updated to use the right https://github.com/juju/utils
    https://github.com/juju/utils/commit/28c01ec2ad930d41fe5acd9969b96284eb61660b

Also per bug 1465317, juju client needs to stop checking its host's version because it is not jujud in a cloud.

[Chris MacNaughton (chris.macnaughton)]

Any eta for this getting distributed?

[Anastasia (anastasia-macmood)]

It has been committed to master tip and will be released as part of 2.0.1 (most likely at the end of this week).

[Jay R. Wren (evarlast)]

I do not think this actually fixes the bug.

Juju is still built with Go 1.6, the resulting executable is effectively not usable on MacOS Sierra: https://github.com/golang/go/issues/17234#issuecomment-256821918

[Curtis Hovey (sinzui)]

Homebrew uses golang 1.7 for sierra and yosemite to create the juju client. MacOS never runs the agent.
