Getting this: “Couldn’t register com.abc.MyApp with the bootstrap server. Error: unknown error code.” when trying to run a unit test in AppCode.

The underlying Xcode version is 4.3.1

The only way to resolve it is restarting the computer.

I cannot even get magsafe to work. The magsafe is connected to the connector, but the battery icon is showing: “Not charging”. Something is a very wrong at the kenrel level.
