Wish to clean install macOS 10.13 High Sierra Beta on your Mac? You need to first create a macOS 10.13 High Sierra USB installer to get through the process with ease. With the bootable USB installation drive, you can easily download the latest macOS on multiple devices; without having to re-download the beta profile.
Before going through the process, make sure you have a USB flash drive of at least 8GB. If you have important files in the drive, get them out of it as they will be completely wiped out. Enough gossip? Let's get through the process!
How to Create a macOS 10.13 High Sierra Beta Bootable USB Drive
Step #1. First up, download the High Sierra Beta installer and keep it in your /Applications folder.
Make sure not to change the default name “Install macOS 10.13 Beta.”
Step #2. Next, you have to insert your 8GB USB drive. Make sure to save all the important files you have stored in the drive before cleaning it up. To keep things simple, name the USB drive as USB.
Step #3. Now, you have to open the Terminal window. Then, paste in the command given below to move the Beta Installer to the USB and make it bootable:
sudo /Applications/Install\ macOS\ 10.13\ Beta.app/Contents/Resources/createinstallmedia --volume /Volumes/USB --applicationpath /Applications/Install\ macOS\ 10.13\ Beta.app --nointeraction
Note: Just in case, you had changed the name of the High Sierra Installer or the USB drive you will have to edit the command. Likewise, if you had moved the Beta Installer from Applications edit the command to reflect its current location.
Step #4. When asked, you have to enter your Account Password.
Now, the USB drive will disappear from the Desktop and Terminal will show the readout of the progress.
When the files have been copied, and the drive is ready to be bootable, the drive will show up again on the Desktop. Then, Terminal will confirm you that the process has been completed.
How to Use the macOS High Sierra USB Installer
Step #1. To use the USB installer, you need to boot your Mac while holding the Option/Alt (⌥) key.
Step #2. Next, select the drive named Install macOS 10.13 Beta.
The Mac will now boot to the macOS 10.13 High Sierra Beta install screen.
