Q: MacBook Pro 2015 overheating and slowing down
I've got a huge problem with my MacBook Pro 2015 (15 inches). When it's getting hotter outside (today it's about 35 deg Celsius in Germany), the Mac gets very hot and slows down until you can hardly use it. I've installed the Intel Power Gadget and can see that the processor is throttled down to 0.8 GHz, which is the reason for the terrible performance. Just recently, I had the machine checked by Apple, and they swapped the motherboard. But even after this, the problem returned once it got warmer again. The only difference is that the kernel task isn't taking up lots of CPU power, the processor is throttled nearly immediately. I don't run CPU intense apps. Any idea what might cause this weird behavior? In Yosemite, I remember there was a trick to reset some setting .plist file, but this doesn't work for El Capitan. I also tried to reset the SMC, but to no avail.
MacBook Pro (Retina, 15-inch, Mid 2015), OS X El Capitan (10.11.6)
