Long time mac user, versed in Linux but have been using Mac for its "convenience" for years: Upgraded to high sierra, and my power modes started working totally irrationally with seemingly no explanation. When I closed the lid it suddenly started going crazy and nearly burnt a hole in my desk. I think it burnt out the logic board in this way, the GPU and kernel started panicking after 2 minutes running. When turned off it would turn itself on and go into this crazy hyper swap mode, the box when I was shipping it to applecare seemed like it would catch on fire. Had to keep using SMC shutdown to get it to turn off. I dont know if the issue was High Sierra, macbook pro 2016 (which are total crap in my opinion why in the world would you hardwire the hard drive into the logic board??), or both, but it suffices to say I'm buying a Thinkpad, and Im only using Ubuntu on it.
