`comfy install` fails on Mac: "Cargo, the Rust package manager, is not installed or is not on PATH"

Describe the bug When using comfy install to install ComfyUI on a Mac M3 Pro, an error is thrown related to "Cargo" not being installed. The end result is, that I can't install ComfyUI.

To Reproduce

Run comfy install
Choose mac_m_series
See the error

Expected behavior I can install ComfyUI on my Mac.

Additional context

Python: 3.13.0
comfy-cli: 1.3.1
MacOS: 15.0.1

Even after installing Rust on my Mac, I see errors:
