How I cleanup about 150 Gb storage of my macbook.
 - Currently, I used mac book that have 256Gb SSD. On an beautiful day, I opened the Storage check, and see that I only have 30Gb left. That's quite shocking. This is my working laptop, shouldn't have any thing that too heavily effect on volumn.

After some check I found that 2 big monster that eaten my volume:
 - Docker: When you used docker, after a while, you would have tons of images, containers, volume, those things are very big on size. So, I use `prune` to clean up all my obsoleted images, containers, volumes.
 - The Cache: The mother of monster is here: `/Users/<your_username>/Library/Caches/`. So, I run: `rm -rf /Users/taynguyen/Library/Caches/`, it takes about 15mins to completed.

Boom, I recovered about 140Gb of my SSD.
What's fun thing. :D
