For #3 that is an issue for remote debugging with things like XDebug for PHP. I have been using this command:
sudo ifconfig lo0 alias 10.254.254.254
And setting the remote host to 10.254.254.254 instead of localhost inside the container to work around that issue. It's been working pretty well.
I've been using the Beta version of Docker for Mac for many months and haven't had many issues with it at all. The biggest issue I've seen was the QCow file not releasing space and growing to 60+GB, but deleting it and restarting Docker did the trick (although I had to rebuild or repull any containers).
