Sierra downloaded and runs but nothing happens ...
Im trying to update to Sierra from OS X 10.8.4 on a 2012 macbook and I have encountered a problem. The installer downloaded and seems to run without errors until it prompts for a restart. After the computer is restarted nothing happens, im still running OS X 10.8.4 and Sierra has not been installed. Does anyone have any suggestions?
