![]() Consistently, the Mac will not boot unless I cut the power to it and then power on. ![]() When I cut the power (on my surge protector) and power back on, then the machine boots. I press the power button and then nothing. ![]() In fact, with up to 64GB memory onboard, it can still outperform the new M1-based Mac Mini in memory-intensive workloads, which ironically do not really require a lot of CPU horsepower at all times, and therefore its power draw in those workloads will not hit the ceiling demonstrated by Apple’s test.

Yet it was a quite powerful machine for its time. ![]() In fact, as far as power efficiency is concerned, the 2018 Mac Mini is the most power-hungry Mac Mini ever. Apple’s measurements are significantly higher than those obtained by AnandTech, which means that Apple indeed uses a burn-in test that stresses all parts of the system, something that arguably happens in any real-world situation. Power consumption of the whole system counts in consumption of all of its components, including memory, storage, connectivity controllers (with the new Mac Mini, we're talking about a bunch of chips that includes Apple's own Wi-fi/Bluetooth (and GbE controller) as well as voltage regulation overhead (something we know from 80Plus badges in the non-Apple world).
