    I bought an older gen Macbook air off of Amazon and I seem to be having issues with it maxing out its CPU or using almost all of it using just a single program, whether it Safari or Visual Studios. I wonder if a part of it is going faulty or if there is some way to fix it. If you have any idea please let me know.

    if you go into Activity Monitor, then choose "All Processes" from the View menu, then sort by % CPU (descending), what is the first item in the list?
