After doing diskutil list:

/dev/disk0 (internal):

and sudo gpt -r show disk0:

I deleted some partitions I was using for a dual boot with Ubuntu using gdisk, but now Disk Utility nor diskutil will show empty space from deleting the volumes. Although my GUID_partition_scheme shows I have 500 gigs on the disk, the space is just gone and no longer able to be expanded to the "Macintosh HD" partition. I tried rebooting but nothing seems to work. Any ideas?

  • @user3439894 It says, "No CoreStorage logical volume groups found" and Disk Utility wouldn't let me delete them, so its not like I had any other choice. – user191609 Aug 27 '16 at 1:22
  • @Midi, Did you try using diskutil from Terminal vs the Disk Utility app to remove what you deleted with gdisk before resorting to it? – user3439894 Aug 27 '16 at 1:30
  • @user3439894 Yes, I tried both. – user191609 Aug 27 '16 at 1:32
  • @klanomath So any ideas? – user191609 Aug 27 '16 at 1:38
  • @klanomath If you add it to the answers, then I'll select it if you want. Thanks. – user191609 Aug 27 '16 at 1:53

Under these circumstances - only one main volume - the proper command to expand it to its full size is:

diskutil resizeVolume /dev/disk0s2 R

This command will not work if your main volume is part of a CoreStorage Volume Group.
