My machine will not run longer than 5 minutes. Sometimes an error comes up, sometimes it just stops. CM will not connect, CM will not open, CM tries to open but the icon sits there and bounces infinitely. Cannot restart my Mac, need to choke it.
Now the wheel of death… I wait, it stops, softwares seems to be fine as if it connected, but nothing.
This problem likely began w/ a premature disconnect caused by electrical grounding issues: http://www.shapeoko.com/wiki/index.php/Electronics#Recommendations
Other people have managed to restore the connection to their Mac by resetting the PRAM (command option p r while rebooting), others have had to reset the System Management Unit, or re flash the Arduino — if what you try doesn’t work, contact firstname.lastname@example.org and they’ll get you squared away.
