There's nothing special about Apple's SMC other than it's got proprietary code and you cannot purchase it from TI.Īpple tells you when you should reset your SMC and all of the reasons have to do with power, temp, sleep, etc. It's a chip made by Texas instruments that manages the flow of current, the fans, monitors the temperature, etc. This is your power controller or what is known in the rest of the computer industry as a PMU (Power Management Unit). It has nothing to do with the running of your Apps or whether some of the keys on your keyboard work or don't. Your NVRAM holds pre-boot environment variables like initial screen resolution, boot volume, Bluetooth keyboard identification, boot chime volume, etc. NVRAM is used with the Intel CPU based Macs. PRAM was used with the PPC (Power Macintosh) like the G3, G4, PowerBook, etc. NVRAM means Non-Volatile RAM (Random Access Memory). Many times you see this incorrectly referred to as PRAM as well. So, what do they actually do? Reset the NVRAM 99% of the time, they are not the right thing to do. So often we see these as the very first go-to suggestions/solutions to every problem that a Mac faces. Resetting Your NVRAM/SMC, Safe Mode, Verbose Mode, and reinstalling macOS I hope I can save you some time and alleviate any consternation with respect to the diagnostic procedures in getting you to a solution to your problem. I wrote the following to shed some light on the some of the commonly held misconceptions regarding the all too familiar procedures for "fixing" a broken Mac by resetting the SMC/NVRAM, resintalling the software, etc.

Your keyboard is broken: Keyboard key stuck or not being recognized how to fix Again, same accident, but this time you just repaint and reupholster the interior.
Same accident, but this time you remove all the bumper stickers, the large spoiler, empty the groceries from the trunk, clean out the glove compartment and put in a fresh, clean tank of gas. This is like getting into an accident where a wheel falls off and thinking that if you can only reset the check engine light, things will work again. None of these things are going to fix a physical issue with your computer. Let's look at this from the perspective of an automotive analogy. The left Shift ⇧ control ⌃ option ⌥ does not respond so I can't reset the SMC Your keyboard is damaged and it needs to be replaced. I was thinking it didn't get any damage, but several keys are not working anymore and the keyboard black light is also down. My MBP (13-inch, 2017, Four Thunderbolt 3 Ports) has been hit by a small object on its keyboard.
