how do you run diagnostics on a 2015 MacBook? I have tried starting up the mac holding the D key down and also option+D but nothing seems to work to get it into diagnostic mode. I have been having issues with programs freezing and needing to be forced quit. I also had a panic crash that pointed to a cpu issue

Core: 0


Thanks in Advance

Hit the (f4) mission control button and go under 'disk utility'.
 
+1 etrecheck

I think it's actually slightly better than Apple's own suite of inbuilt diagnostics.
 
really, it comes down to what might be wrong. programs freezing? a kernel panic? honestly, it might be worth trying to call apple. what errors does etrecheck show?

EDIT: maclife magazine recommends 'maccheck' from micromat.com, another freebie...

Thanks and sorry for the late reply I will try this and let you know it probably will not be for a couple days
[doublepost=1476221785][/doublepost]Ok I was able to run it a little bit ago. But it doesn't really show any issues. but here is the CPU Panic error
