Before I installed rEFInd, I believe there were three partitions to my Mac, disk0, disk1, disk2.

Now, when I run in the Command line

 diskutil list

This is what remains:

    #:                       TYPE NAME                    SIZE       IDENTIFIER
    0:      GUID_partition_scheme                        *500.1 GB   disk0
    1:                        EFI EFI                     209.7 MB   disk0s1
    2:                  Apple_HFS Macintosh HD            499.2 GB   disk0s2
    3:                 Apple_Boot Recovery HD             650.0 MB   disk0s3

I'm not sure what to think of this. Previously /dev/disk0s2 was Apple_CoreStorage of a size around 499 GB. Then there was a /dev/disk1, which was "Apple_HFS Macintosh HD". Notice that's now disk0s2 above.

Should I worry? Thankfully I have everything saved on an external hard drive.

EDIT: If it helps, my HD used to look like the second screenshot on this web tutorial, after diskutil list. http://www.theinstructional.com/guides/disk-management-from-the-command-line-part-1

  • That's a pretty standard GPT partition layout. Looks fine to me. – Fake Name May 26 '15 at 3:09
  • @FakeName My only concern really is that "Apple_CoreStorage" seems to have disappeared. That's strange. – ShanZhengYang May 26 '15 at 3:32
