I don't know why my retina MacbookPro keeps crashing and how to fix My mid2014 retina pro keeps crashing, can't boot into safe mode and can't choose utilities when booting into recovery mode because no mouse commands are accepted. (not sure what key combo would choose a utility such as disk recovery) it resolves itself over time--not sure how.  

I Kept the log from last night's crash == 92 pages so i tried to post what might be relevant but i really have no idea.  Any help is greatly appreciated, thanks in advance
