So I did some research and found another post on AskDifferent that explained how to delete a partition from terminal (in recovery mode) by first unmounting the physical disk using diskutil unmountDisk /dev/disk0 and then deleting the partition using gpt remove. However the option to delete the BOOTCAMP partition is disabled in Disk Utility. So what I thought I could try is delete my BOOTCAMP partition, which is about 100GB, and then merge the free space into the problem partition so that I can run fsck -fy in single user mode to try to repair the volume which now will have enough space to complete the operation. Now the disk is greyed out in disk utility and I can't reinstall mac os x because I would need to erase all of the data on the drive and I don't want to lose the files I have on it. Sorry I didn't get any screenshots or anything but that is basically what happened. (I had about 13GB of free space at this time) Then it tried to restore the disk to it's original state on mount but it couldn't do this either, I'm guessing because of lack of disk space.
So I opened in recovery mode and ran the first aid and it tried to fix the B-Tree of the catalog file, however there wasn't enough disk space to do this.
If you don’t want to proceed with partitioning the disk, click Cancel.Īfter the operation finishes, click Done.Īfter you partition a storage device, an icon for each volume appears in both the Disk Utility sidebar and the Finder sidebar.I was trying to repair permissions today on my Mac so I ran the Disk Utility's First Aid on my drive and it said that there was an Invalid Index Key and that my disk was corrupt and I needed to run the first aid in Recovery mode.
If you want to proceed with partitioning the disk, click Continue. If a dialog appears that indicates it will take a long time to resize the startup volume, read the information in the dialog, then do one of the following: Read the information in the Partition Device dialog, then click Partition. Type a name for the volume in the Name field.įor MS-DOS (FAT) and ExFAT volumes, the maximum length for the volume name is 11 characters.Ĭlick the Format pop-up menu, then choose a file system format.Įnter the size or drag the resize control to increase or decrease the size of the volume. Note: If you click Add Volume instead, you can click the Add button to create an additional APFS volume in the container, or click Cancel to return to the Disk Utility window without making any changes to the storage device.
