A one-click setup for a fresh macOS install to my specifications: Homebrew, apps, and system preferences get configured automatically, then a series of guided steps walk you through anything that needs a click or a login.

Download Mac Setup

First run only: macOS blocks scripts downloaded from the internet by default.

Unzip the download, then right-click install.command and choose Open (don't just double-click it), then confirm Open in the dialog that appears.

If you already double-clicked it and got blocked, go to System Settings → Privacy & Security and click Open Anyway next to the warning about install.command.
