I am having the exact same issue when it comes to not being able to reclaim space as in the answered question below...

Reclaim hard drive space from deleted partition and reclaim Apple bootloader

I went into terminal and compared my data to the solved and could not figure out which index I need to be focused on while in recovery mode. And is there a way I can send a message or ask a question to a specific person on this site such as the person who had solved the above issue? Please any help is really appreciated! Some Terminal info is below.

  • The problem here is a little bit different compared to the linked question: 1. you have two Recovery HDs and 2. your main volume is a CoreStorage stack. – klanomath Jun 04 '16 at 07:23

Though similar to the linked question your partition table has some specific differences: you have a second Recovery HD with a false partition type and your main volume is part of a CoreStorage stack.

First you have to determine the proper system versions of the Recovery HDs and then remove the older or - if identical - remove the one with the wrong partition type (disk0s4). After removing one of the Recovery HDs you have to resize the CoreStorage stack:

Preparation:

  • Restart to Internet Recovery Mode by pressing alt cmd R at startup.

    The prerequisites are the latest firmware update installed, either ethernet or WLAN (WPA/WPA2) and a router with DHCP activated.
    On a 50 Mbps-line it takes about 4 min (presenting a small animated globe) to boot into a recovery netboot image which usually is loaded from an Apple/Akamai server.

    I recommend ethernet because it's more reliable. If you are restricted to WIFI and the boot process fails, just restart your Mac until you succeed booting.

    Alternatively you may start from a bootable installer thumb drive (preferably Yosemite or El Capitan) or a thumb drive containing a full system (preferably Yosemite or El Capitan). If you boot to a full system and login as admin you have to prepend sudo to execute some commands like gpt ... or newfs_hfs ...!

Check system versions of Recovery HDs

  • Open in the menubar Utlities->Terminal
  • Enter diskutil list and gpt -r show /dev/disk0 to get an overview

  • Get the product version of the visible Recovery HD:

    grep ProductVersion -A 1 /Volumes/Recovery\ HD/com.apple.recovery.boot/SystemVersion.plist

    depending on the main system version it should yield something like:

    <key>ProductVersion</key>
<string>10.11.5</string>

  • Unmount disk0s4:

    diskutil unmount disk0s4

  • Mount the hidden Recovery HD partition:

    diskutil mount disk0s3

  • Check that only one Recovery HD (disk0s3) is mounted:

    df

  • Get the product version of the invisible Recovery HD:

    grep ProductVersion -A 1 /Volumes/Recovery\ HD/com.apple.recovery.boot/SystemVersion.plist

    depending on the main system version it should yield something like:

    <key>ProductVersion</key>
<string>10.11.5</string>

  • If the product version of the visible is the same or older than the one of the invisible Recovery HD delete the visible Recovery HD partition:

    diskutil list
diskutil umount diskX #Unmount the logical volume residing on disk0s2 with X: 1...~16 (e.g. disk1) like shown in the previous command
diskutil umountDisk disk0
gpt remove -i 4 disk0

  • Get the UUID of the logical volume:

    diskutil cs list

  • Resize the CoreStorage stack to fill the whole disk:

    diskutil cs resizeStack lvUUID 0 #lvUUID: UUID of the logical volume

    The 0 (zero) as magical size sometimes fails. Then use a size ~1g smaller than your disk size (i.e. 250g or 249700m).
