macOS: Removing all Homebrew stuff

Join the AI Workshop to learn more about AI and how it can be applied to web development. Next cohort February 1st, 2026

The AI-first Web Development BOOTCAMP cohort starts February 24th, 2026. 10 weeks of intensive training and hands-on projects.

Stuff just accumulates over time.

I looked into the /opt/Cellar folder, which holds all the Homebrew packages, and it was 10GB.

So I found this suggestion and ran:

brew remove --force $(brew list --formula)

and then

brew remove --cask --force $(brew list)

to remove all commands and apps installed through Homebrew.

Then I reinstalled just the thing I needed.
