Ah sorry minutes, they bill the most for macOS probably because of what a pain it is to scale it with apples EULA (I'm guessing) https://docs.github.com/en/billing/reference/actions-runner-...

ah ok, minutes makes more sense. thanks.

Mins here being short for minutes, not minis.

And, presumably for a combination of the Mac build (and hardware) being of niche interest and sitting outside the standard Linux workflows so it's annoying to administer. And serving a money-making audience (iOS app devs) who have a revenue stream and see the extra CI cost as worth it.

What is a macOS mini…

Not “mini”, “mins” -> minutes.
