Preferred Order of NVRAM/PRAM, SMC, and OS resets Is there a preferred order in which I should reset the NVRAM/PRAM, SMC, and OS on my MBP?

If so, what is this order (and why)?



Edit: I intend to do all of them to completely reset my computer. No need to explain what each does, I know what they do.
Yes, don’t do any of these until you have a very specific reason to do each. They handle entirely different functions so cycling through each of them would be equivalent to not even refining what you want to handle.

Take a medical analogy:


bandages are for cuts
anti-inflammatory is for swelling
anti-pyretic is for fever
rest and liquids are for colds
antiboitics are for infections


Prescribing the wrong treatment just wastes time and can cause further injury if you’re not treating the actual problem at hand.
