[OSX] 'No Drag&Drop has been setup. Please' error when dragging any item in Unity



- This issue happens seemingly at random, with no rhyme or reason. There are a few threads with users experiencing this problem, but it's not that frequent.

1. Download project: Drag_Bug
2. Open "scene_main" scene
3. Press Window > Open TreeView Test Window
4. Try Drag and Drop for example "Red" on "Blue"

  1. Resolution Note (fix version 2019.2):

    Hard to repro, and affects few users.

    Still there on 2018.1.0b13 - Mac OS Sierra 10.13.3. It looks like it functions but I still get the error message.

    Also reproduced in Unity 2017.2 Beta (Mac OS Sierra 10.12.5), with one difference being that the drag does work now, but the errors are still logged in the console (many times per drag in my case).
