Snagged a MacBook from a auction dirt cheap for wife(I hate MacBooks). Missing 2 keys ordered replacements other than that perfect. BUT computer is slower than my grandma. System is running 90% user is 10%. Kernel_task is running 375.2% (what the fuk) how do I fix this.


/also ordered a new hard drive from eBay and on the hard drive it has some Carbon Copy Cloner? Can’t find shit about it online but assuming it makes copies of the operating system and the seller transfers into a bunch a hard drives? Idk I need help should I return the hard drive?

Very delayed here, but can you give more detail about the MacBook?

What year is it?
What version of OS X is it running?
Is it a clean install or did you just make a new account?

Also, if possible, upgrade it from a hdd to a ssd.

Activity Monitor calculates CPU usage by combining each core into a cumulative CPU total. So each core is 100%, and a 4-core CPU (i5, etc) will be 400% in activity monitor. It's odd, but it is how Apple does things.
