Below, we are going to run through the steps that are required in order to create a bootable macOS USB drive for a clean install. You’re obviously going to need a USB 3.x USB-C or USB-A drive with a minimum of 32GB capacity. [BUY]
- Download the macOS installer from Mac App Store.
- Once downloaded, close the installer that automatically pops up. You don’t want to be installing it just yet.
- Open a Finder window and head to Applications. Right-click on Install macOS 10.14 and select the Show Package Contents option.
- Open Contents > Resources. You’re going to need something from this sub-folder from here in a minute.
- Fire up Terminal either via Spotlight or from Applications > Utilities. Once open, type sudo followed by a space.
- Drag the createinstallmedia to that newly opened Terminal window.
- Now enter the following command, which will once again be followed by a space: –volume.
- Next up and back in Finder, select Go > Go To Folder. In here type /Volumes and click the Go button.
- Connect your USB drive and watch for it appearing in the Finder window.
- Drag the USB drive volume into the still open Terminal window.
- Press return, submitting the command that we just built via the magic of drag and drop.
- Type a y when prompted and hit return again.
- This whole process can take around 30 minutes and will see the USB drive be erased before the installer is copied over.
You now have a bootable USB drive which you can use to install macOS. You can do this by connecting the USB to your Mac and restarting it while holding the Option (⌥) key. The macOS installer will appear and you will be ready to go.
