Not to mention the lack of host:container socket sharing and the fact that the Moby VM time drifts due to system sleep. I love Docker for Mac, I use it every day, and it's definitely still beta quality.
How much does your time drift? We changed the mechanism so that it should sync from the OSX ntp server now, which seems to be giving good results. If you are having problems can you create an issue and we can look into it.
Host container socket sharing will come, but it is complex as sockets only exist with in a single operating system, so we have to bridge them across two. We are using this for the docker socket, and debugging the issues across Mac and Windows, so it is in the roadmap.
Actually GA may have fixed this. I was able to reproduce it, but may have checked too quickly. I opened https://github.com/docker/for-mac/issues/17 against it, and may end up closing it.
