The Two Installing Options for macOS Catalina

• You can put Catalina over the Mac’s current settings
• You can run a clean install

This is a tutorial on how to clean install macOS Catalina, so we’ll be talking about the second option. But first, let’s explain what both alternatives mean.

The Ultimate Guide: How to Clean Install macOS Catalina

Step 1: Back Up the Data You Need

Since the clean install of macOS Catalinawill delete everything from your hard drive, you should back up important data, so you won’t lose it. You can use iCloud, Dropbox, or any other cloud-based service to do that. If you don’t have too many files and everything is already on iCloud, you’re good.

But if you have a lot of files that aren’t on the cloud, uploading them would be a long and stressful process. You can opt for Get Backup Pro – a simple app that creates bootable clones of your important files.

• Return. When the system asks for your admin password, provide it.
• Wait for the procedure to go through. Once you see the Done button, click on it.

What Makes Catalina So Good?

Some Mac users don’t want to bother with the installation process. They got a Mac because of the easy user experience, and all this seems too complicated. They start thinking: “I’m okay with Mojave, so why should I bother?”

There are a few aspects that make Catalina better than Mojave:

• An opportunity to use iPad as a second screen to your Mac, thanks to the Sidecar function.
• Functional updates to Photos, Find My, Reminders, and other native apps.
• An option to use a subscription gaming service: Apple Arcade.

1. Back up your data

First, back up everything. Your Mac probably contains your personal data and documents that you don’t want to lose. So, to keep those alive after the downgrade, you need to back up your data.

You can use Google Drive, iCloud Drive, or any other cloud you prefer. After the backup is done, you can move on to the next step.
