Fusion Drive Free Space

I have a 2.12 TB Fusion Drive on my iMac that says it has Macintosh HD 1.06TB partition and a Free Space 1.06TB partition. I'm assuming the Free Space is left over from when I had Windows installed via BCA. How can I reclaim this Free Space partition? Here's what it looks like in Disk Utility


Thanks for the help.

iMac 27″ 5K, macOS 10.13

Hello!


Before making any major partition changes in Disk Utility, make sure you have a Time Machine backup of your Mac:


Back up your Mac with Time Machine - Apple Support.


Next, shut down your Mac, then startup into Recovery Mode (Command-R) by immediately pressing and holding those keys at startup. Then, open Disk Utility, and select "View" > "Show All Devices". Click "Partition" on the "Fusion Drive" entry.


Are you able to select "Free space" and click the minus (-) to delete it? That space should then be added back to Macintosh HD.


If not, are you able to manually enter the full "2.12 TB" in the "size" entry for Macintosh HD?
