kqueue doesn't support character devices like PTY before Mac OS 10.9. This issue is discussion on Tulip mailing list, no decision was taken yet how to fix this issue.

ERROR: test_read_pty_output (test.test_asyncio.test_events.KqueueEventLoopTests)

During handling of the above exception, another exception occurred:

The issue was discussed here:

The decision is to skip the test on Mac OS X < 10.9.
