Install osx on new hard drive from usb

A fresh start! Installing macOS on a new hard drive from a USB drive is a great way to start from scratch. Here's a step-by-step guide to help you through the process:

Preparation

  1. Backup your data: Before installing macOS, make sure you have backed up all your important files and data to an external hard drive or cloud storage service.
  2. Create a bootable USB drive: You'll need a bootable USB drive with the macOS installation media. You can create one using a Mac with a USB drive and the built-in createinstallmedia command, or use a third-party tool like Etcher.
  3. Prepare your new hard drive: Connect your new hard drive to your Mac and make sure it's recognized by the system. You can use the Disk Utility app to format the drive and erase any existing data.

Installation

  1. Insert the USB drive: Insert the bootable USB drive into your Mac.
  2. Restart your Mac: Restart your Mac and immediately hold down the 'Option (⌥)' key. This will bring up the boot menu.
  3. Select the USB drive: Select the USB drive with the macOS installation media from the boot menu.
  4. Follow the installation prompts: The installation process will begin. Follow the prompts to select your language, country or region, and keyboard layout.
  5. Select the hard drive: Choose the new hard drive as the installation destination. You may need to format the drive, so make sure you're prepared to erase all data on the drive.
  6. Install macOS: The installation process will begin. This may take some time, depending on the speed of your hard drive and the size of the installation.
  7. Set up your Mac: Once the installation is complete, you'll be prompted to set up your Mac. Follow the prompts to create a user account, set up your network, and configure other settings.

Post-Installation

  1. Install any necessary updates: After setting up your Mac, you may need to install any necessary updates to ensure you have the latest security patches and features.
  2. Transfer your data: If you backed up your data before installing macOS, you can now transfer it back to your new hard drive.
  3. Customize your Mac: Take some time to customize your Mac to your liking, including setting up your desktop, installing any necessary apps, and configuring your security settings.

That's it! You should now have a fresh installation of macOS on your new hard drive.
