Just like Windows, macOS also gives us a seamless option to format the hard drives for Mac (and PC). The operating system has an inbuilt tool, which is known as Disk Utility. Using it, you can erase a hard drive, create new partitions, and even repair your disk as well. Plug your HD into the Mac and open Disk Utility, which can be accessed by searching for it in Spotlight. Then, select your hard drive from the left sidebar. Now go to the Erase tab.
These instructions apply only to Mac computers with an Intel processor.
Erasing your Mac permanently deletes all of its files, so make sure that you make a backup of any files that you want to keep. If you're attempting to restore your Mac to factory settings, first learn what to do before you sell, give away, or trade in your Mac.
