Installation with Virtualbox 4 present fails, requires uninstall/reinstall of Docker

Expected behavior

I installed on a Mac that had Virutalbox 4.3. Uninstalling Virtualbox should resolve the issue. It would also be nice if Docker installer checked for presence of Virtualbox before progressing, as the incompatibility was unexpected.

Actual behavior

Both Docker and Virtualbox needed to be uninstalled, and Docker installed again. Frustrating but can be worked around.

Information

OSX 10.11.4
Docker Version 1.11.1-beta10 (build: 6662)

Steps to reproduce the behavior

  1. Install Virtualbox 4.3
  2. Install Docker 1.11.1-beta10
  3. Launch the Virtualbox DMG and select the uninstall tool to uninstall Virtualbox
  4. Launch Docker – hangs
  5. Uninstall docker
  6. Reinstall docker
  7. Launch Docker – works
