Yes, I know this question has been asked many, many times. I promise I have tried everything all of the solutions that I could find. I'm running OC X El Capitan on a MacBook Air.

My latest attempt was to delete my Bootcamp partition with diskutil in Terminal. Output from diskutil list:

   #:                       TYPE NAME                    SIZE       IDENTIFIER
   0:      GUID_partition_scheme                        *251.0 GB   disk0

   5:                  Apple_HFS DELETEME                50.5 GB    disk0s5
/dev/disk1 (internal, virtual):
   #:                       TYPE NAME                    SIZE       IDENTIFIER
   0:                  Apple_HFS Macintosh HD           +199.0 GB   disk1
                             Logical Volume on disk0s2
                             1BF2795D-D4B7-4C5C-BD7A-4243ADA8BD64
                             Unlocked Encrypted

But then the minus sign was grayed out in Disk Utility when I went to finally delete it and merge my harddrive back together.

So I tried to merge Bootcamp with my Apple core storage using diskutil and I got a message that 'the chosen disk does not support resizing.'

The chosen disk does not support resizing.
Do you wish to format instead? (y/N) 

I am at a loss. I have tried everything.

    What model Mac? What version of Windows? What version of macOS? Output from diskutil list? Output from diskutil cs list? Output from sudo gpt -r show /dev/disk0 run from installation flash drive or Internet macOS Recover. – David Anderson Mar 23 '18 at 2:38
  • Not quite everything....backup, nuke and pave. – ArchonOSX Mar 23 '18 at 11:01
  • Ok, I've added the output from the various diskutil commands. Ideas? – MeC Mar 23 '18 at 14:45

You need to remove the Apple_HFS and Microsoft Reserved partitions before recovering the free space. The commands to enter are given below.

sudo  diskutil  erasevolume  free  n  disk0s5
sudo  diskutil  erasevolume  free  n  disk0s4
sudo  diskutil  cs  resizestack  1BF2795D-D4B7-4C5C-BD7A-4243ADA8BD64  0
