Install macos 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 with a clean slate. 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 macOS High Sierra or later, 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 your 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: Once you've set 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. Install any necessary software: You may need to install any necessary software or applications to get your Mac up and running.

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