MacOS system files took up excessive storage. This script deletes files that I believe are safe to be deleted inorder to free up storage.

macos_cleanup.sh

#!/bin/bash

# Instructions:
# 1) Open Terminal
# 2) Change file permissions "chmod +x macos_cleanup.sh" 
# 3) Then run the file "./macos_cleanup.sh"

# Append filepaths to be removed here. Removes reports, backups, archices, cache, etc.
