Problem Installing Elk2 on Mac: Rhino WIP

I have dragged Elk.gha and all other files into the correct folder, but elk components do not show up in the toolbar. 

Errors given in rhino command:

Command: Grasshopper
The Elk2 component library was build against an older version of the Grasshopper SDK:
The current SDK: 1.0.6226.26143
The referenced SDK: 1.0.0.20
An error occured during GHA assembly loading:
Path: /Users/KevanKasmai/Library/Application Support/McNeel/Rhinoceros/MacPlugIns/Grasshopper/Libraries/Elk2.gha
Loader Exceptions:
Exception System.IO.FileNotFoundException:
Message: Could not load file or assembly or one of its dependencies.

----
Main Exception:
Exception System.Reflection.ReflectionTypeLoadException:
Message: The classes in the module cannot be loaded.

I would really like to get this component installed, so any help would be greatly appreciated
