I ran Disc Inventory X to see where the excess space was taken.
1. Remove old iPhoto library.
Look at this screenshot from Disk Inventory X: The pink section surrounded by the yellow line is my old ‘iphoto’ library. The large turquoise section to the left is the new ‘Photos’ library. El Capitan came with a new app called ‘Photos.’ The new Photos app imported my old iPhoto library, but it didn’t delete it! They are the same photos, the entire library has been duplicated. Deleting my old iPhoto library released almost 7 G of space!

While I was at it I went to my ‘Applications’ folder and deleted the old ‘iphoto’ app which took up 1.7GB.
I could do this pretty confidently because my macbook air is my second machine, all my photo’s are only home computer if anything goes wrong.
