Unity3d: Drag & Drop setting not installed

Question

I was working on a Unity 2D game project on OS X 10.10 and I cannot drag a file or folder, it will show this error.

No Drag&Drop has been setup. Please
UnityEditor.DockArea:OnGUI()

I tried:

• save the project and then reload
• click Assetsfolder and selectReimport All

But it doesn't seem to work, how to fix it?

Answer 1

Unity uses NSPasteboard (the general OSX clipboard manager) to store data for Drag & Drop, so any process that controls / modifies the clipboard can be messy with Drag & Drop.

Answer 5

Based on @ user3130047 answer, this is another version. Mac only.

• Get out of unity.
• Place this command in the console and execute it.
  
  ps aux | grep pboard | grep -v grep | awk '{print $2}' | xargs kill -9 | launchctl start com.apple.pboard
  
• Open unity.
  

It.

But this can lead to your other open copy of applications and pasting not working. Therefore, you need to restart them.

Answer 6

This is the easiest way to accomplish the best answer:

killall -HUP pboard

(from a terminal or similar, obviously)
