MacBook Pro not booting
MacBook Pro (OS X 10.11.3) was working heading into last weekend, coming out of it, it can not boot properly. Can't think of a reason why this would suddenly be the case. Shut down normally & was working fine. Since restarting it would only load up to a point in the startup & go no further.
Any suggestions/solutions?
Thanks.
