I have an M4 Max and when I was trying out local LLM work with pi it has probably felt like the hottest I've ever felt any kind of Macbook be. I could feel the radiated heat off it even a few inches away. Honestly felt hotter than any Intel Macbook I've used. Because of that I stopped as I didn't want to harm my laptop in case I need to hold it for 10 years due to all the supply issues/price increases.
