My MacBook Pro 15 2018 is too hot I bought a 15'' MacBook Pro a few days ago and it gets too hot under load. Idle temperatures are about 40-50 degrees light use 60 degrees but opening a light game like league of legends will set the CPU at 80-90 degrees.
I want to know if this is normal or not and if it will damage my battery.I still have time to return the laptop. Thank you.
I presume you mean 40-50 degrees C, not F. 

Yes, that's pretty normal. I'm just browsing the web with Safari, and my laptop is at 111 degress F
