How to Upgrade macOS
There are two ways to upgrade macOS: directly in Mac App Store, or upgrade using an USB device.
No matter which way you choose, always remember to back up your data before performing an upgrade.
Time Machine Backup
Apple has its own official backup tool: Time Machine. This feature was released in OS X 10.5 Leopard. If you have never backed up, let me tell you how important it is.
Time Machine can connect to your Mac and any external hard drive via USB, FireWire or Thunderbolt port. Back up everything on your Mac directly to your hard drive, in case the Mac cannot upgrade properly.
It also supports Apple’s Time Capsule and backup disks connected over a network as long as the disks support AFPS. As long as the disk is available to your Mac, you can use it for Time Machine backups.
When enabled, Apple’s Time Machine will periodically transfer all files and store data on an inserted external hard drive or on a Time Capsule connected to the network.
You can choose hourly, daily or weekly backup to store your data on the external hard drive. When the external device is full, Time Machine will delete the oldest backup and replace it with the newer version.
Let’s check how to enable Time Machine backup on Mac devices.
1. Choose “System Preferences…” from the Mac menu.
2. Double-click the Time Machine icon.
3. Click “Select Backup Disk…” to select the disk you want to use as a Time Machine backup.
4. Select the “Back Up Automatically” check box so that your Mac will automatically back up data to your chosen disk.
If you want to restore files from Time Machine, make sure your Mac is running. Click “Enter Time Machine”, find the previous file or folder, and then click “Restore.”
Besides Time Machine, you can try other great backup and restore software such as Carbon Copy Cloner (CCC) and SuperDuper.
1. Direct Upgrade in Mac App Store
Generally, you can upgrade your system directly in the Mac App Store by clicking “Check for Updates” or click the following link to download macOS High Sierra:

If you use a Beta version, you still need to click the link above to download the system, or go to the developer’s website for download information.
If you want to choose “USB clean upgrade”, check the detailed information below.
2. Upgrade using USB device

i. USB Preparation
Before formatting your current operating system, download macOS High Sierra from the Mac App Store first. You will need a copy of macOS High Sierra to perform a clean installation later. If you want to upgrade to this version, it is possible as long as your current operating system version is lower than macOS High Sierra.
Natively, look for “Disk Utility” in your application, select an external USB device with a capacity of 8 GB or larger, format it directly, and remember to choose the format “Mac OS Extended (Journaled)”. If it is a hard disk, it would be better to make a partition beforehand.
If you have already downloaded the macOS High Sierra package, do not click on the installation. Directly open the “terminal” program, which you can find in the application.
When typing the following text in the terminal, check the name of the formatted external USB device. If you do not name it “Untitled”, you need to change the command syntax of the path name: Volumes/Untitled. The names of external USB devices cannot contain spaces and are case sensitive.
sudo /Applications/Install macOS High Sierra.app/Contents/Resources/createinstallmedia –volume /Volumes/Untitled –applicationpath /Applications/Install macOS High Sierra.app –nointeraction
Press “Enter” on your keyboard to execute the command. You will then be prompted to enter the administrator password. It will start the process after the operation, which can take a long time, depending on the transfer speed of the external USB device. When done, the terminal window will report “Done.”
