Cloning a hard disk in MacOS is a bit easier than Windows because you can use its tool Disk Utility Built-in to perform the same function. However, there are many third-party alternatives, such as the popular Carbon Copy Cloner, but Disk Utility does the job well. You don't need the latest version of MacOS Mojave, but it's never a bad idea to keep your Mac up to date.

Step 1:Start on a different volume

The only disadvantage of Disk Utility compared to some third-party tools is that it disassembles all drives to speed up the copy process. That means you cannot make a clone of the hard drive you are currently working with. You should start from another drive or volume with a running MacOS installation or use the volume of Recovery HD.
