How to install osx on new hard drive

Installing macOS on a new hard drive is a bit more involved than installing Windows, but it's still a relatively straightforward process. Here's a step-by-step guide to help you through it:

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. Download the macOS installer: Go to the Apple Support website and download the macOS installer (e.g., macOS High Sierra or later) from the "Download macOS" page.
  3. Create a bootable USB drive: You'll need a bootable USB drive to install macOS. You can use a tool like DiskMaker X or create a bootable USB drive using the Terminal command sudo /Applications/Utilities/Install\ macOS\ [version].app/Contents/Resources/createinstallmedia --volume /Volumes/Install\ macOS\ [version] --applicationpath /Applications/Install\ macOS\ [version].app.
  4. 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. Restart your Mac: Restart your Mac and immediately hold down the 'Option' (⌥) key while booting up. This will bring up the boot menu, where you can select the USB drive as the boot device.
  2. Select the USB drive: Select the USB drive from the boot menu and press 'Enter' to boot from it.
  3. Select your language and country: Follow the on-screen instructions to select your language and country.
  4. Agree to the terms: Agree to the terms and conditions of the macOS installer.
  5. Select the installation type: Choose the installation type: "Install macOS" or "Reinstall macOS" (if you're upgrading from an existing installation).
  6. Select the hard drive: Select the new hard drive as the installation destination. You may need to format the drive first.
  7. Wait for the installation to complete: The installation process will take some time, so be patient and let it complete.
  8. Set up your Mac: Once the installation is complete, you'll be prompted to set up your Mac, including setting up your user account, Wi-Fi, and other preferences.

Post-installation

  1. Transfer your data: Transfer your backed-up data from the external hard drive or cloud storage service to your new hard drive.
  2. Install any necessary updates: Install any necessary updates to your macOS installation using the App Store or Software Update.
  3. Set up your Mac: Set up your Mac as you normally would, including setting up your user account, Wi-Fi, and other preferences.
