I'm still rather new to my MacBook but so far I love it. Could someone help me with something. I want to delete some unwanted files I may have downloaded that takes up some of my memory. I have quite a few vids but their all in a designated folder so I know how many Gb it takes up. It just does not add up, it seems like I have quite a few more Gb taken up by something. Is there a way to find out what stuff I put on my computer that it did not originally come with? I want to get my Gb back to a higher number but dont want to delete needed applications. Thanks people
