I dont think thats an correct interpretation of the EULA, they are just choosing to ignore it - https://wiki.licenseware.io/catalog/rules/apple-macos-lease-...

If a business reserves a Mac for 24 hours (and allows no other users for that window), it complies with the EULA, no?

That doesn't mean the business has to charge the user for 24 hours. You could charge for 6 hours and then just let the Mac sit idle and unused the remaining 18.

You're eatting the cost of that unused time, but if its a differentiator that leads to more business than it might still be worth it.

I don’t think they are doing this.

From the wording of the parent comment my understanding is that 24 hour period applies to the MacOS VM, not the hardware itself. Since they split each physical host into at least 2 different VMs the 24 hour period is for that VM. Even stronger case if they also lock the core affinity to the physical layout like Max editions having multiple Pro chips/dies within...

For Amazon EC2 the case is different since it doesn't allow VMs but only possible to get dedicated bare-metal hosts. Obviously Amazon could offer VMs but they would not because the current way allows them to charge 24 hours even if user uses the host only 1 hour. And obviously no body big enough challenging the status quo and impacting AWS' revenue hard enough.
