Macbook pro 13'' late 2011 excruciatingly slow
I have a macbook pro late 2011 that is running slow. On startup the fan is running on high revs and it will start after about 10 minutes or so. On CPU usage it the kernel task is using about 200%.
n. b. i recently bought it and i have zero knowledge of its history
MacBook Pro 13″, OS X 10.11
