It's pretty much all in the question, but here are some specifics.a couple of specific info.

I'm running macOS Sierra.Sierra

I've downloaded the latest versions:

• versions: * RhinoWIP: 5.3 WIP (5D129w)
• (5D129w) * GHPython 0.6.0.3 (worked until there),
• there), * Ladybug 0.0.63 and Honeybee 0.0.60.

I've copied ItemSelector.gha into ~Library/Application Support/McNeel/Rhinoceros/MacPlugIns/Grasshopper/Libraries, and all of the *.ghuserfiles into ~/Library/Application\ Support/McNeel/Rhinoceros/MacPlugIns/Grasshopper/UserObjects

Now when I try to launch Grasshopper (via the ExplicitHistory command), Rhino becomes unresponsive.

Has anyone successfully used Ladybug/Honeybee on mac?
