I have two MacBook Pros each with Docker for Mac installed. Today one updated to 1.12.0-rc3-beta18. The other states that version 1.12.0-rc2-beta17 is the latest. I removed the 1.12.0-rc2-beta17 Docker app and re-downloaded but it once again shows as: 1.12.0-rc2-beta17.
Did they pull the 1.12.0-rc3-beta18 update? Seems strange I have two machines each with different versions and each stating they are at the latest version.
