Windows os deleted, Partition Space is not returned.
I wanted to allocate more space to windows so I deleted the partition through bootcamp. I then checked the storage of my Mac to find that the Macintosh HD partition still had 750 GB of storage partitioned for it. However the system recognises the 1 TB Fusion Drive. How can I partition the remaining 250 GB of storage for the Mac too.
