"Other" taking up over HALF of my storage space
You can try Daisy Disk and it will give you a pictorial view of your drive and what is taking up space. It has a free trial so you can use it without buying it.  There is also a free app called Disk Inventory X which does about the same but lists the sizes of everything it "sees". It also makes a colored map of you disk. I highly recommend you use these to scan your disk. 

How can I figure out what&#39;s slowly eating my HD space?
