I downloaded Ladybug Tools 1.5.0 however Honeybee has this error.
Please see Ladybug Tools | Forum for questions related to the Ladybug Tools.
You are still running legacy Ladybug tools, It is not supported on mac.
make sure you only use V1.5 components (it should be on a separate tab) these components will show 1.5 version under each component.
Since these legacy plugins are not mac compatible, I suggest removing them.
