Once you have selected it, click on the Erase button at the top of the window and then enter a name for your disk in the pop-up window that appears. Finally, choose either Mac Extended (Journaled) or APFS as your format option before clicking Erase once again to confirm your changes.

So if you’re looking for a quick way to refresh your computer without losing any data or information, look no further than Disk Utility in Mac OS High Sierra!
