}}}

    b. heavy docker desktop, business paid {{{
brew install --cask docker
}}}

 3. AI note: Colima is especially popular among developers on Apple Silicon Macs (M1, M2, M3, M4, M5) because it uses Apple's own virtualization (VZ) and can enable Rosetta for running Intel/x86 containers efficiently.
