How to permanently delete photos from iPhoto and Mac
Version OSX 10.9.5
I backed up all photos to my external hard drive and now I'd like to remove them permanently from my MacBook and clear up the 36G of space they are taking up.
Went into iPhoto, selected all photos and deleted them
Went into iPhoto>Trash and emptied it
Went to the System Trash and deleted the photos there
Found a copy of my iPhoto Library via Finder and deleted it.
Yet, somehow, the space has not cleared up on my Hard Drive. It still has exactly the same amount of available space as before I did all of that deleting and trash emptying. I have spent approx the past hour searching through forums on the internet, but have not found a solution that works.
Can anybody help me? Thank you in advance.
MacBook Pro (Retina, 13-inch, Late 2013), OS X Mavericks (10.9.5)
