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.

To clean install Mac OS from USB, there are three things you should do. First, you should clean up your Mac from the old baggage — system files that have piled up over time. 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.

We’ve got the steps outlined below, so let’s get to it.

Step 1: Clean system junk on your current Mac OS X

Whatever OS X you are currently on, system junk and outdated cache files are a potential source for software conflicts. Having cleaned them up, you may discover around 35 GB of newly created space previously taken by junk. What's more, old caches may interfere with your new Mac OS X installation, so this step is pretty essential.

Cleaning can be done either manually or using a dedicated app. If you don’t want to spend the next 20 minutes on repetitive clicking and typing, jump right to the automatic solution further down.

The manual way to remove old user caches:

  1. Click on a Finder window and choose “Go to Folder” in the Go menu.
  2. Type in ~/Library/Caches and click Enter to go open the folder.
  3. Go through each of the folders and remove their contents.

Note: Do not remove the folders themselves, just their insides. Kontakt 5 full version.

Next off, do the same steps, but now replace..

~/Library/Caches with… /Library/Caches

Step 2: Back up your Mac

Before you begin to reinstall Mac OS from USB, you should back up your Mac. Note: If you don’t do this step, you will not be able to recover files, nor restore anything if something goes wrong. To back up your Mac:

  4. Click “On” on the left-hand side of the screen to turn Time Machine on.
  5. On the right, under the name of the storage device, there are three lines that say, “Oldest backup,” “Latest backup,” and “Next backup.” Your backup should be scheduled within the next 5 minutes.
  6. Don’t want to wait? In the menu bar at the top of your screen, a few icons left of the Date & Time, click on the “arrow clock” icon and select “Back Up Now.”

Step 3: Installing Mac OS from USB

You will need 3 essential things:

  • The OS X Installer (downloaded from the App Store)
