Why Should We Upgrade to macOS High Sierra?
Apple released the latest macOS, High Sierra, and added some new features including a new and improved Apple File System (AFPS), a faster browser, stellar graphics, better gaming capabilities and VR support. MacOS 10.13 is absolutely worthwhile to upgrade your Mac.

You can download and install macOS High Sierra OS for free in 2009 or later. Basically, if your Mac is currently running macOS Sierra system (macOS 10.12), you can smoothly upgrade to macOS High Sierra.

- Mac mini (Mid 2010 or newer)

Some features, such as High Efficiency Video Coding (HEVC) encoding and decoding require newer processors and devices, some of which unfortunately cannot run on older devices.
If you are running OS X Lion (10.7.5) or later, you can upgrade directly to macOS High Sierra.
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.
