But I was much less excited about cloud macOS options for CI.</p> <p>GitHub charges <a href="https://docs.github.com/en/billing/reference/actions-runner-pricing">$0.062 a minute</a> for their cheapest macOS runner, ten times the Linux rate. A 20-minute build is $1.24. Push twice a day and macOS CI alone is over $50 a month. That was surprising enough that I went and measured what the money buys.</p>
