last week my dev laptop (MacBook Pro 13-inch, 2019, Four Thunderbolt 3 ports) went super slow. The laptop fan was working at high speed, it sounds like a bitcoin miner.
I was curious to see what happened. Nothing was working correctly, really weird!.
I opened the Activity monitor and checked processes and app resource usage. CPU usage was normal, then I moved to the memory, it was fine, and then I moved to the disk usage. OH! There were just a few megabytes free.
How it was possible, I use this Macbook just for working purposes.
I used the grandperspectiv to visualize the HDD usage.
and found these 3 major reason:
- docker.raw (64GB )
- node_modules folders
- Application cache (chrome, Mozilla, developer tools, yarn and nvm)
solutions:
- you can change the size of docker.raw in docker settings ( have a look at this link
- I suggest using this command in your home folder to remove node_modules in all old packages
find . -name 'node_modules' -type d -prune -exec rm -rf '{}'
- clean npm and yarn cache
Just by these 3 simple solution I freed up to 100GB of my disk storage.
