docker, waiting for SSH to be available

I installed docker CE and its ToolBox on "MAC OSX Yosemite 10.10.5", and when I launch the "Docker Quickstart Terminal" I get the message below saying waiting for SSH to be available and asking for a password. Please suggest a solution, any answer will be highly appreciated.

Go to launch VirtualBox, check for updates (at top left, beside the Apple icon), Update VirtualBox then I solved this.

ps: I also changed VirtualBox(default) setting enter image description here
