Tips: How to Clean Install macOS Catalina
1. Check if Your Mac Can Handle It
Before you figure out how to clean install macOS Catalina, it's important to know if your device is compatible with the release. These are the devices that support it:
- All iMac Pros
- iMacs from 2012 on
- Mac minis from 2012 and on
- Mac Pros from 2013 and on
- MacBook Pros from 2012 and on

2. Choose the Type of Install You Want to Upgrade to
Apple gives you two upgrade options for macOS Catalina:
- Install macOS 10.15 Catalina while preserving all data intact. Most people have important files on their computers. Losing them would probably be a total disaster. Imagine a writer losing all their documents or a control freak losing their apps. Of course, the cloud is always there, so you can always recover things that get lost. But learning how to install macOS Catalina without losing any of your data will lead to a less stressful experience.
- A clean install for a fresh start. This gives you the feel of a brand new computer. During the installation process, all system junk will be gone and you'll be left with a clean slate. This is a good option for those who don't need any of the data on their computer. Maybe it's full of photos and documents that you transferred on an external drive. If you don't need anything, a clean macOS Catalina installation will make your computer faster. But even if you do this type of install, you might want to back up some of your data. This is the type of install we'll be talking about in the continuation of this article.
