Installing macOS on a clean hard drive involves a few essential steps that can help ensure an optimal setup. This guide will walk you through the entire procedure, perfect for users who want a fresh start with their system.Prerequisites
Before you begin, you need to prepare the following:- A USB drive with at least 16GB of storage.

Step-by-Step Installation Process
1. Download macOS Installer: Start by downloading the macOS installer from the App Store. Ensure that you have the correct version compatible with your Mac. 2. Create a Bootable USB Drive: You can create a bootable installer by using the Terminal application.

Select the USB Drive: Choose the USB drive with the macOS installer. Once selected, press Return to continue. 5. Open Disk Utility: Before installing, it's advisable to format your hard drive. Once the macOS installer loads, select "Disk Utility" from the Utilities window. 6. Erase Your Hard Drive: In Disk Utility, select your main hard drive (usually named "Macintosh HD"), then click on "Erase." Use APFS or Mac OS Extended (Journaled) depending on the macOS version you intend to install. 7. Close Disk Utility: Once the formatting is complete, close Disk Utility to return to the installer. 8. Install macOS: Choose "Reinstall macOS" from the menu and follow the on-screen instructions to complete the installation. Enter your Apple ID and set up your preferences as prompted.Post-Installation Tips
