10 tests fail on macOS

[marcelstoer]

This was triggered by #150 (comment).

The Travis file guided me to running the tests locally on my Mac. For some reason, I didn't investigate why, some of the tests fail.

Regardless of what the outcome is here I suggest to have the Travis CI build also run on macOS.

What's the pendulum version you are using? Are you sure those tests ran on the current master?
I had the same issues with pendulum 2.0.0 which API is currently not compatible with maya.
That's why maya pins the pendulum version in setup.py for now: https://github.com/kennethreitz/maya/blob/master/setup.py#L28

[marcelstoer]

Are you sure those tests ran on the current master?

I thought it was master - until I noticed that you force-downgraded pendulum in this upstream repo only 4 days ago. I pulled in that change and now all is well.
