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.

The latest version is macOS Mojave, which was publicly released in September 2018. UNIX 03 certification was achieved for the Intel version of Mac OS X 10.5 Leopard and all releases from Mac OS X 10.6 Snow Leopard up to the current version also have UNIX 03 certification. Sep 25, 2020 If your Mac is using an earlier version of any Mac operating system, you should install the latest Apple software updates, which can include important security updates and updates for the apps that are installed by macOS, such as Safari, Books, Messages, Mail, Music, Calendar, and Photos.

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Whatever OS X you are currently on, system junk and outdated cache files are a potential source for software conflicts.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.

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:

1. Open an app called Time Machine.
2. Click “Select Disk.”
3. Select where you wish to save your files (an external drive works best, Apple Time Capsule is a safe bet).
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)
• The backup of your old system
• Startup drive to install OS X on

Once it’s all prepared, it’s time to clean install OS X. But first, you need to create a bootable drive using a USB containing Mac OS X of your choice. Don’t know how? Then read on.
