Excellent.
It is readily accepted that Linux reduces overhead versus Windows on the same system.
What is less readily accepted is the same result versus macOS. Yes, it is considerably more work to get Linux running well on a Mac, since it is ultimately a closed ecosystem. But the point should be made that macOS also has a lot of unnecessary overhead over which the user has little or no control.
The PC vs Mac thing should be dead by now, tbh, in favor of corporate vs FOSS.
