Ask HN: Should I buy mac studio M4 max or macbook M5 pro?

A developer working with AI coding agents asks whether to buy a Mac Studio M4 Max or a MacBook M5 Pro for a system that runs continuously day and night, seeking advice on which is more worth the investment.

Background

- The user is choosing between Apple's Mac Studio (a powerful desktop, M4 Max chip) and a MacBook Pro (laptop, M5 Pro chip) for running AI coding agents around the clock. - "AI coding agents" are software tools that autonomously write, review, or debug code using large language models (LLMs). Running these locally requires sustained high compute power, often maxing out CPU/GPU for hours or days. - The M4 Max (Mac Studio) offers more GPU cores and unified memory than the M5 Pro (MacBook), making it better for sustained AI workloads. But it's a desktop — no battery, no portability. - The MacBook Pro (M5 Pro) is portable but can throttle performance under sustained load due to thermal limits and battery drain; running it plugged in 24/7 may degrade battery life faster. - This trade-off is common for developers: desktop = raw performance + longevity vs. laptop = flexibility + slower speed + potential wear.

It notes that even third-party developers are constrained by Apple's rules, while a few apps like BBEdit and Fantastical still maintain strong icon identities.
