How to erase a disk Proceed based on whether you're erasing your startup disk or some other disk. Your startup disk is the disk volume that your Mac started up from. By default it's the disk built into your Mac, named Macintosh HD.
The steps above also work when erasing a storage device that you're not using as a startup disk. And you don't need to delete data volumes first: just select your disk in Disk Utility, then click Erase. In some circumstances, you might need to change the partition map scheme while erasing.
If you're following instructions that require choosing a scheme, the steps in Disk Utility differ from the steps above. Are you formatting the disk that came built into your Mac? Are you about to install macOS High Sierra or later on the disk?
If you need to erase your disk before installing High Sierra or later for the first time on that disk, choose Mac OS Extended Journaled.

Thank you for the informations. It's running fine this way.For now, though, the Terminal is our friend. Once there, issue this command to find out where your APFS container lives:.
My output looks like the image below. Locating your APFS container prior to resizing it. You use the same command for both processes, but you might be likely to want to reduce the size of your APFS partition first, perhaps to install another operating system on your Mac. We need to use sudo here, to take administrative privileges over the Terminal session. I could have also issued the command like this, and diskutil would automatically determine the size for my new partition:.
Note that in my case, I could replace disk0s2 with disk1 for either command, since my APFS container is located at disk1.
The diskutil command automatically locates the physical store for my APFS container, and resizes things accordingly. If you decide you want to reclaim that space into your APFS container, you can do that using diskutil as well. This command will do the trick, assuming your volume is named disk0s3. In this case, diskutil automatically claims all available free space on the physical storage device, but you can also replace 0 with a size value.
You will notice that your Mac becomes unresponsive for a time, as it verifies the filesystem, checks everything out, and then carries out the resize operation. I live on the bleeding edge, though, and did this from the live filesystem without any data corruption. This site uses Akismet to reduce spam. Learn how your comment data is processed.
