I wouldn't buy any Mac products for LLM usage. It's cheaper to just buy a subscription. You enjoy Mac for your personal/professional use. I have been running LLM on Mac, honestly for such an expensive machine I wouldn't want to use it for long runs just for a quick 30 minute usage. It heats up so much you can make an omelette on it. I would NOT want my dedicated MacBook run hot for long these things last forever. Fairly confident if I run LLM's all day long their life will be short lived. In my family my kids are still using their laptops which are papas handovers. I have an iMac from 2014 that my kids still use.
