Frequently asked questions
What does a battery replacement cost on the MacBook Pro 16''?
DKK 2,200–2,600 including labour and 2 years' warranty. A larger battery (100 Wh) than the 14'' version, but the same workflow. See current pricing at macmo.dk/reparation.
What's the difference between the 14'' and 16'' Pro?
Display: 14.2'' vs. 16.2''. Battery: 70 Wh vs. 100 Wh. Cooling: the 16'' has larger heatsinks → better sustained performance on Max chips. Weight: 1.55 kg vs. 2.15 kg. Price: typically DKK 5,000–7,000 more for the 16''.
Should I pick the Pro or Max chip?
The Pro is enough for 90% of pro work (code, web, photo, lighter video). The Max only pays off for heavy GPU workloads (4K+ ProRes editing, 3D, Stable Diffusion locally). Difference: ~DKK 3,000–6,000 extra for the Max.
