Running display_manager.py show on my Mac (running 10.14 (18A365a)) gives this warning:

/System/Library/Frameworks/Python.framework/Versions/2.7/Extras/lib/python/PyObjC/objc/_bridgesupport.py:674: RuntimeWarning: Error parsing BridgeSupport data for IOKit: PyObjCRT_SkipTypeSpec: Unhandled type '0' warnings.warn("Error parsing BridgeSupport data for %s: %s" % (frameworkName, e), RuntimeWarning)

before it outputs the expected information:

display "main":
resolution:     1440x900
refresh rate:   0
HiDPI:          True
rotation:       0
brightness:     1.00

Similarly display_manager.py help gives this warning:

Hello @tjluoma:

Thanks for taking the time to post back about this issue. We will investigate and troubleshoot and reply back on status.

@tjluoma,

Thank you for letting us know about this issue. We've been able to reproduce it, and are investigating the cause right now. However, it looks like attempting to set the resolution, brightness, rotation, underscan, or mirroring all work as intended (albeit with the unexpected RuntimeWarning). Let us know if you've experienced a different result, and we'll try to get to the root of the problem soon.

The error is distracting, but everything seems to work fine.

@tjluoma

Thanks again for letting us know about the issue. We've found the source, and it won't affect Display Manager -- PyObjC is simply sending a general warning about incompatibility within a part of IOKit that we don't use. Everything else is working, so we've suppressed the warning in v1.0.1. If you'd like to reinstall using the latest installer, you'll no longer be distracted by the warning.
