So I was playing around with Disk Utility today. I created a second partition. Format is Free Space.
How do I undo this? As in, I want to have just one primary partition "Macintosh HD"
1) In Disk Utility, I select the partition tab. The "-" character is greyed out. As in, it cant be clicked on.
2) Rebooted in Recovery mode (CMD+SHIFT+R) and did above. Same result. The partition cannot be removed. The "-" button is greyed out. It simply cannot be clicked.
This is what
diskutil list returns:
