Hello, I would like to know if there's a way to check all components of my macbook's hardware. I am aware there is a hardware test if you hold D when rebooting, however if I shut down my macbook it has problems booting up and doesn't respond to any commands, so I would like to avoid having to turn the laptop off. I'm trying to see if any part of this laptop is failing or has something wrong. Thank you!
MacBook
Pro, OS X El Capitan (10.11.6)
