From 1.1.8, if mkcert is installed, create and rename turn HTTPS on and reissue the shared certificate. Local HTTPS “like production” is part of Free, not a checkout extra.
If Safari does not trust it:
- Doctor / refresh HTTPS (
macstack https refresh).
- In Keychain Access, set the mkcert local CA to Always Trust.
Chrome often accepts it before Safari. Default HTTPS port is 8443 (80/443 — Settings → Ports).
Download 1.1.8 and create a project: you no longer tick HTTPS by hand.
