Rick ChurchillRecently my "13inch early 2015 MacBook Pro" often restarts when left idle. Sometimes the mouse curser becomes "sticky" and video on Youtube will stutter as if the CPU is under too much load. As I write this I realise I should have looked at Activity Monitor to see if I can work out what is loading the CPU.
What should I look for and is there any other diagnostic apps I can try?
The report says "Fatal Error"
