Lost partition space after deleting a Bootcamp partition

[jkkruse]

Hi all.

I've been struggling with a loss of space on my Macbook for the past year or so after I've deleted a Bootcamp partition and ever since I've been limited to 185 GB on my macbook and not the 251 GB that I originally had. I'm not even able to locate the remaining 66 GB in my disk utility list. Finally, my mac is stuffed so I do not have any space left and therefore I need to get back the lost disk space.

Is there anyone out there who are able to help me out?

The read out from my diskutil list is as follows:

/dev/disk0 (internal, physical):

#: TYPE NAME SIZE IDENTIFIER

0: GUID_partition_scheme *251.0 GB disk0

1: EFI EFI 209.7 MB disk0s1

2: Apple_APFS Container disk1 185.0 GB disk0s2

/dev/disk1 (synthesized):

#: TYPE NAME SIZE IDENTIFIER

0: APFS Container Scheme - +185.0 GB disk1

Physical Store disk0s2

1: APFS Volume OS X Base System 179.1 GB disk1s1

2: APFS Volume Preboot 45.6 MB disk1s2

3: APFS Volume Recovery 517.1 MB disk1s3

4: APFS Volume VM 3.2 GB disk1s4

Your Mac partition is 185gb, is this correct?
Then, you need an EXTERNAL drive about 250gb in size. It can be either a USB flashdrive, or a USB external drive.

Once you have that, do this:
1. Connect the USB drive to the Mac.
2. Open Disk Utility and erase the external drive. Choose "GUID" partition map, then choose APFS.
3. Once the flashdrive is erased/initialized...
4. Download CarbonCopyCloner from here:
http://www.bombich.com/download.html
(CCC is FREE to download and use for 30 days - you won't need to register it)
5. Open CCC. Accept all CCC's defaults for now
6. Put your Mac partition (from the internal drive) "on the left". This is your SOURCE.
7. Put the external USB drive "in the middle". This is your TARGET.
8. Click the clone button. If CCC asks if you wish to clone the recovery partition as well, YES, you want to do this.
9. The clone will take some time, as the entire contents of your Mac partition get "cloned over".

Now, when CCC is done, do this:
(we're going to "reclone" the clone BACK TO the internal drive)
1. RESTART the Mac.
2. IMMEDIATELY hold down the option key and KEEP HOLDING IT DOWN until the startup manager appears.
3. Select the external cloned backup and hit return.
4. The MacBook should boot from the cloned backup. It will take a little longer if it's a platter-based drive.
5. Get logged in and to the finder.
6. Open "about this Mac" (Apple menu) and be sure that you're booted from the cloned backup
7. Open Disk Utility
8. In DU's upper left, make sure that "all devices" is shown in the popup menu.
9. Select the topmost in the list representing the INTERNAL drive.
10. Click ERASE and choose GUID partition map and APFS file system
11. Now, ERASE the internal drive back to a SINGLE PARTITION
12. When done, quit Disk Utility and re-open CCC
13. This time, put the BACKUP drive "on the left"
14. Put the internal drive "in the middle"
15. Click "clone" and let CCC do it's thing (again, clone the recovery partition if asked).

When done, power down, all the way off.
Disconnect the cloned backup
Press the power on button and "do the option key trick" again.
Select the internal drive and hit return.
Do you get a good boot?
Check to see that there is now only one partition, using the full amount of disk space available.
ONE MORE THING:
Open the startup disk preference pane. Click the lock and then select the internal drive as the boot drive.

Now, restart once more.
Do you get a good boot to the login screen?
Login ok?
You're done.

YES, this is going to be some work. But it WILL "work".

Bit of advice:
Don't be botherin' with BootCamp again. It's not worth the trouble.
