How to create a bootable macOS Catalina installer drive Put the macOS Catalina installer on an external USB thumb drive or hard drive and use it to install the operating system on a Mac. Performing a factory reset on your MacBook or Mac can solve many macOS problems, and is essential if you're selling. Here's how to reset a Mac, whether it's an iMac, Mac mini or MacBook.

Downloading and installing a new OS gives you the opportunity to do some major house cleaning if you so desire. If you feel like you'd like a fresh start with macOS Catalina, you can always opt to do a clean install: Just follow the steps below, even if you've already installed macOS California.

Make sure you understand the difference between a clean install and a standard install before you get started.

Note: If you are reading this article on the Mac you want to perform the clean install with, switch to another device or print this page before continuing so you can read along as you go.

Step 1: Back up your Mac

This process will erase whichever OS you're currently using from your hard drive entirely. That means any files, programs, or documents you have will be deleted. To save your files, put them on an external hard drive or a cloud-based program like Dropbox, OneDrive, or iCloud. If you don't save these important files off your computer, you will lose them.

Step 2: Create a bootable drive of macOS Catalina

Before you erase your current operating system, download macOS Catalina from the Mac App Store. You'll need a copy of macOS Catalina to perform a clean install later on. If you don't create a bootable drive for macOS Catalina, you may have to install an older Mac operating system first and then upgrade to macOS Catalina afterward.

Step 3: Erase your hard drive

1. Connect your Mac to the internet via Wi-Fi or Ethernet
2. Click on the Apple icon.

3. Select Restart from the drop-down menu.

4. Hold down Command-R when you hear the startup chime (or the screen turns black on newer Macs) and keep holding the keys until your computer reboots.
5. Click on Disk Utility in the OS X Utilities selector.

6. Click Continue.

7. Select your Startup Disk.

8. Click on the Erase tab at the top of the window.

9. Enter a name for the file to be destroyed (Like macOS Mojave or something).
10. If your Mac is using HFS+, select Mac OS Extended (Journaled) from the format list. If your Mac is using APFS, select APFS from the format list.
11. If Scheme is available, select GUID Partition Map.

12. Click Erase.

Step 4: Reinstall a new copy of macOS Catalina

1. Click on Reinstall a new copy of macOS.

2. Click Continue.

3. Click Continue again when the installer window appears.
4. Agree to the software terms and conditions.
