The new MacBook Pros based on the M1 Pro and M1 Max SoCs proved to be very productive in a number of tasks. But mining is definitely not one of them.
There is already a video on the web with a test of a new laptop based on the M1 Pro, and the result cannot be called even just modest. The PC demonstrates a performance of 5 MH / s, which is very, very little. For example, the budget GeForce GTX 1650 reaches about 12 MH / s.
True, the power consumption of the laptop during mining is limited to only 17 W, but this still does not neutralize the very low performance. Of course, the payback depends on the rate of the cryptocurrency at a particular point in time, but at the moment the MacBook Pro will pay off for about 17 years.
A MacBook Pro based on the M1 Max with a top-end GPU will clearly perform better, but such a laptop is also more expensive. And even with a doubling of productivity, this is still very, very small.
