woops accidentally did solved on bootcamp

You can run

diskutil eraseVolume free free disk0s3

which will convert it to Free Space, or you format it as HFS+ or FAT32.

You will lose the ability to run Local Recovery.

Before you erase, test if Command+R during Reboot does give you the Recovery console without a spinning globe.

Unless you erased the incorrect disk slice, based on

dev/disk0 (internal, physical):

#: TYPE NAME SIZE IDENTIFIER

0: GUID_partition_scheme *1.0 TB disk0

1: EFI EFI 209.7 MB disk0s1

2: Apple_CoreStorage Macintosh HD 796.4 GB disk0s2

3: Apple_Boot Recovery HD 203.6 GB disk0s3

the Recovery HD should have been converted to Free Space. Can you run the commands in Recovery which I posted earlier and post the output.

In Recovery Console, click on Utilities -> Terminal, run

diskutil list disk0

Select, Copy (Command+C) the output of the Terminal session, quit Terminal, start Safari (Get Help Online), and Paste (Command+V) the output as a reply to this discussion.

No worries. I responded to the other discussion.

We can convert the current 200GB to free space, but your CS is not revertible, so absorbing Free Space will still be an issue.

If you run

diskutil list disk0

can you Select, Copy (Command+C), quit Terminal, start Safari (Get Help Online), and Paste (Command+V) the output as a reply to this discussion.
