Aug 10, 2020 macOS Recovery makes it easy to reinstall the Mac operating system, even if you need to erase your startup disk first. All you need is a connection to the Internet. If a wireless network is available, you can choose it from the Wi-Fi menu, which is also available in macOS Recovery. Next, click Erase and after Disk Utility does its thing, quit Disk Utility. You should return to the MacOS Utilities window. (If not, restart your Mac again, holding down Command-R while it reboots.). You need to put your MacBook ($630 at Back Market) into recovery mode in order to erase all of your data and reinstall MacOS. To enter recovery mode, restart your Mac and immediately press and hold. In that mode, when you choose to reinstall without erasing the drive, my recollection is that Recovery looks for the current OS system installer on your startup disk in the Applications folder.
Most users use Disk Utility to erase a disk or hard drive. But some Mac users might need to erase them from the command line on Mac OS. To do that, the only thing you need is a bit of precise syntax to make sure that you are erasing the proper disk.
Here I'll show you how you can erase and format a disk using the command line.
Working with Terminal
Start off by running the following command in the command line: Diskutil list
This is going to list all the mounted drives on your Mac.
Once you have found the proper drive to erase, just copy its identifier so you can use it for the next command. Then pick a name and a system format type. This is the syntax we need: Diskutil eraseDisk FILESYSTEM DISKNAME DISKIDENTIFIER

Let’s say the disk I want to erase has “/dev/disk5s2” as its identifier and I’m going to use Mac OS Extended Journaled (JHFS+) as the system format type and name it “Empty”. The syntax is going to look like this: Diskutil eraseDisk JHFS+ Empty /dev/disk5s2
It’s important to keep in mind that if you run the eraseDisk command, the target disk is going to lose all its data, so make sure you are erasing the proper disk.
