Why is my MacBook running slow after replacing the display?
I replaced my MacBook using the ifixit guide for my MacBook Early 2015 Retina display 13" and it has been running extremely slow ever since. I checked the activity monitor and "kernel_task" is taking about 300% cpu to run. Also occasionally the fan will run extremely loudly. I ran a hardware diagnostic but the only thing that popped up was that the battery needed to be replaced. I'm thinking that there might be a sensor that is inaccurate due to a bad connection. Any help would be greatly appreciated as I just spent 400 dollars to get a new screen only to be left with an extremely slow MacBook.
