You have to rent it for a minimum of 24 hours. I don't know if this is in 24 hour increments, but lets say you need 1 build a day then you are already paying for it every day.

There must be some existing tooling to let you integrate a physical mac you have lying around into your build system, so comparing rental macs vs bought macs isn't so strange.

At work, we use GitLab CI for this and have one of the developers' old MBPs sitting on a rack shelf for this very purpose.

Ah the old load bearing Mac Mini approach :)

It was said on launch day - they bill for the 24 hours upfront, then in 1 second increments after.

The issue with spinning it up "on demand" is that there is a minimum 24-hour billing period for each machine you start because of Apple's EULA. So, each time you want to spin up an AWS Mac, you're paying at least $25.99.
