Those who still rely on older Mac OS X operating systems, know these still are going strong. There are so many things you can do with past OS X — like Lion, Mavericks or Yosemite — each one of these operates flawlessly. So if you're looking to give your Mac a fresh start with just a classic Mac OS X and nothing else, to clean install Mac OS from USB is the best option for you.

Once it's all cleaned up, the next you should do is backup your newly cleaned Mac. And finally, after doing a backup, you can clean install OS X of your choice from USB.
