How do I speed up a MacBook Pro?

If you're using Google Chrome as your browser, look at the top right corner, at the end of the search bar. You should see three dots in a vertical line. Click on them. A list should pop up. Mouse over the option that says "More Tools," and click "Clear Browsing Data." If you're using Safari as your browser, look up at the Apple menu bar at the top, that has "File" and "Edit" and all that jazz. If you see an option that says "Develop," click on it. Near the bottom of the list, there is an option that says "Empty cache." Select it. If you don't see "Develop," click "Safari>Preferences>Advanced Settings>Show Develop Menu in menu bar."
