Question: Almost 50% of storage is used by "Other" on MacBook Pro
I have a MacBook Pro 13-in, Early 2011 with a 2.3 GHz processor and a 320 GB SATA Disk Hard Drive. When I installed OS X El Capitan last year, I noticed significant performance loss, so much so to the point where I haven't been able to use the computer it is so slow. I just replaced the battery (which was beginning to swell) turned off File Vault, deleted almost everything including all iPhoto and iTunes delete folders, re-indexed my spotlight, and STILL have 154.41 GB of "Other" storage. I'm not sure what I can even do to get that storage back.
Any help would be great! I've tried almost everything listed on all of these forums and nothing has helped.
MacBook Pro, iOS 10.3
