To perform a clean installation of macOS 10.15 Catalina, the most reliable method is to download the installer directly from Apple and create a bootable USB drive. While "DMG" files are common on third-party sites, using the official Create Install Media process is the safest way to ensure your system remains secure and stable. 1. Download the macOS Catalina Installer
Apple provides official links to the Mac App Store for older versions of macOS. Official Link: Download macOS Catalina
Process: Click the link to open the Mac App Store. Click Get. This will open the Software Update pane in System Settings. When prompted, confirm the download.
Result: Once finished, an app named Install macOS Catalina will appear in your /Applications folder. Do not run it yet. 2. Prepare Your USB Drive
You will need a USB flash drive with at least 16GB of space. Plug in the drive. Open Disk Utility (Applications > Utilities). Select your USB drive and click Erase. Format: Mac OS Extended (Journaled) Scheme: GUID Partition Map Name: Give it a simple name like MyVolume. 3. Create the Bootable Installer
Instead of a raw DMG, macOS uses a command-line tool to turn the installer app into a bootable disk. Open Terminal (Applications > Utilities).
Paste the following command (assuming your USB is named MyVolume):sudo /Applications/Install\ macOS\ Catalina.app/Contents/Resources/createinstallmedia --volume /Volumes/MyVolume
Press Enter and type your administrator password (characters won't show).
Type Y to confirm erasing the drive and wait for the process to reach 100%. 4. Perform the Clean Installation
Now that you have your bootable media, follow these steps to wipe your drive and install Catalina:
Backup your data: A clean install deletes everything on your Mac. Shut down your Mac. Insert the USB drive. Boot to Startup Manager:
Intel Macs: Turn on the Mac and immediately press and hold the Option (Alt) ⌥ key.
Apple Silicon (M1/M2): Turn on the Mac and continue to hold the Power button. Select Install macOS Catalina from the screen. In the Recovery window, select Disk Utility.
Select your internal hard drive (usually "Macintosh HD") and click Erase. Use APFS format.
Close Disk Utility and select Install macOS. Follow the prompts to finish the setup. Compatibility Check
Before starting, ensure your Mac supports Catalina. Generally, this includes: MacBook: Early 2015 or newer MacBook Air/Pro: Mid 2012 or newer iMac: Late 2012 or newer Mac mini: Late 2012 or newer
Note: macOS Catalina was the first version to drop support for 32-bit apps. Ensure your essential software has 64-bit updates before upgrading.
