Preparing The External Usb Drive
To prepare the external USB drive for installing macOS, you will first need to format the drive to ensure it is compatible with the operating system. Make sure to back up any important data on the USB drive before proceeding, as formatting will erase all existing content. To format the drive, connect it to your Mac and open Disk Utility. Select the USB drive from the list of available drives, choose Erase, and select the macOS Extended (Journaled) format.
Next, you will need to create a bootable macOS installer on the USB drive. Download the macOS installer from the App Store and run the installer to launch the setup wizard. Follow the on-screen instructions until you reach the ‘Select a Destination’ screen. Here, choose the external USB drive as the installation location. This will create a bootable installer on the USB drive, allowing you to install macOS on your Mac from the external drive.
Once the bootable installer is created, safely eject the USB drive from your Mac and it will be ready for use in installing macOS. Having a prepared external USB drive ensures a smooth installation process and gives you the flexibility to install macOS on multiple devices as needed.
Creating A Bootable Macos Installer
To create a bootable macOS installer on your external USB drive, you will need to download the macOS installer from the Mac App Store. Open the App Store, search for the macOS version you want to install, and click ‘Download’. Once the download is complete, the installer will launch automatically, but make sure to quit the installer as soon as it opens.
Next, format your USB drive to ensure it’s ready to become a bootable installer. Connect the USB drive to your Mac, go to Disk Utility, select the USB drive, and erase it using the appropriate format (usually Mac OS Extended Journaled). Then, give it a name like “Untitled” and select ‘Erase’. Once the drive is formatted, open Terminal and enter a command to create the bootable installer. Simply type ‘sudo /Applications/Install\ macOS\ [macOS version.app]/Contents/Resources/createinstallmedia –volume /Volumes/Untitled’ and press ‘Enter’.
The Terminal will ask for your admin password, after which it will start creating the bootable installer on your USB drive. This process may take some time, but once it’s done, you’ll have a fully functional macOS installer on your external USB drive ready for installation on any compatible Mac computer.
Configuring Bios Settings
To configure the BIOS settings for installing macOS from an external USB drive, start by restarting the computer and entering the BIOS menu by pressing the designated key during startup, such as F2 or Del. Once in the BIOS settings, navigate to the Boot tab using the arrow keys on your keyboard.
In the Boot tab, change the boot order sequence to prioritize booting from the external USB drive. Locate the option for changing the boot order and set the external USB drive as the first boot device. Save the changes and exit the BIOS menu. This step ensures that your computer boots from the external USB drive when installing macOS, rather than the internal hard drive.
Lastly, ensure that any other unnecessary boot devices are disabled or removed from the boot order to prevent any conflicts during the installation process. Double-check that the changes are saved before exiting the BIOS settings. Configuring the BIOS settings correctly is crucial for a successful installation of macOS from an external USB drive.
