Security Cleaner Mac Hard Drive

A clean install represents a fresh start, and its achieved by erasing all data from the Mac hard drive and then performing a fresh clean installation of MacOS Catalina onto that Mac.

A clean install sort of feels like getting a new Mac in the sense that no data is on the device at all, there are no apps, no user accounts or user data, no system preferences or customizations, there is nothing left on the Mac at all, its just a blank new installation of MacOS Catalina.

Be sure you have a complete backup of your Mac and all important data made before proceeding.

All personal data, apps, files, and anything on the Mac is erased in this process.

Do not proceed unless you are comfortable removing all data and have backups made.

The Mac will reboot itself automatically during the process, let it finish and do not interrupt the installation.

Nonetheless if you are encountering problems with MacOS Catalina, check out this troubleshooting guide for help addressing macOS Catalina problems.

Some users still use Mavericks and even Snow Leopard and earlier releases, it all depends on personal use case and what is necessary for a particular workflow.

MacOS Catalina works great for some users but not for others, and some of the changes make Catalina impractical for use (like if you require 32-bit app support).

For a true fresh start with a clean install, most users dont want to bring existing data and configurations over anyway, but that means everything must be reconfigured and setup again admittedly, a hassle.

Thats still fairly time intensive and more complicated than a simple update to macOS Catalina, however.

Because theyre a hassle to reconfigure everything, reinstall apps, transfer personal data, etc, to get everything back to how it was prior to the clean install, its not widely used for simply updating macOS.

In other words, how do you get a clean install of your data, now that you have a clean install of your OS.

For personal data that is kept within particular applications, its a bit trickier and depends on those individual apps and where they store stuff.

For the majority of users, its much easier to simply update an existing macOS installation.
