Hi, I have a Macbook air from 2017, just got it under a month ago… I have tried resetting the SMC many times and it has successfully worked fine… although after a couple of days, it is back to normal again… I do this because the batterylife is draining a little too fast and the fan makes loud noises without having barely anything open. I was thinking if there was a way so I didn’t have to reset the SMC all the time? Thanks
