I know I'm too hobbyist- and small-business-minded for lots of folks on HN, but that monthly fee is a mind-boggling non-starter for me. I know that cloud services are never the cheapest option and I don't want to come off as a skinflint, but AWS' Mac pricing is just absurd. Two months' rental pays for the machine outright (three, if you upgrade the RAM or storage). I wouldn't leap into running a public-facing service on a machine parked in the back corner of an office somewhere, but it's not a big deal if your CI/CD machine goes offline for a few minutes if power or data connectivity stumbles.
