Lost space after removing bootcamp partition via bootcamp assistant please help 
i lost 150gb space after deleting the partition via boot camp assistant and the disk utility won't recover it or partition it as one disk 
i tried to recover by timemachine but the disk looked the same size and iam afraid the restore wont get the space back
Try to extend the size in the last shown screenshot by entering a new size in the field or dragging the white dot to the top in the chart on the left.

If this does not work, you need to manually resize the CoreStorage via the recovery system. Look here how to do it.
