Un-Partitioning Hard Drive Error on MacBook Pro
Good Day everyone,
I have MacBook Pro 2013 with OSX El-Capitan 10.11.4. I had windows installed on Boot Camp and I erased the content of its partition by mistake from the disk utilities. I then tried to reinstall it but couldn't so I went back to disk utilities to format, un-partition and then re-partition it all over again. However I had the problem shown in the pictures when I tried to un-partition it. It refuses to remove the pink part and shows it as a free unused space. Any help please!!
MacBook Pro, OS X El Capitan (10.11.4)
