Common Questions

Why buy a refurbished 15-inch M4 Air instead of new?

It's the same machine Apple sells today — same M4 chip, same 15.3-inch Liquid Retina display, same macOS 26 Tahoe — for a serious saving, fully tested and graded honestly, with a 12-month warranty and free next-day delivery. The only differences are cosmetic and the price.
Should I choose 16GB, 24GB or 32GB?

16GB (the M4 standard) is genuinely enough for almost everyone, including Docker and local AI dabbling. 24GB or 32GB is for keeping heavy workloads open simultaneously — photographers with huge catalogues, serious multitaskers.
What's the difference between Fair, Good and Excellent?

Purely cosmetic — every Mac is fully tested and works perfectly regardless of grade. Fair has noticeable scratches or light dents (our best value), Good shows light signs of use, and Excellent looks like new. See our grading guide with photos.
Can it drive external monitors?

Yes — the M4 Air drives up to two external displays with the lid open, a first for the Air. Ideal for docked desk and trading setups.
What's included, and what about warranty and delivery?

Every Mac comes with a fully compatible charger, a 12-month RTB hardware warranty, 14-day returns, an 85%+ battery-health guarantee (under 400 charge cycles) and free insured next-day UK delivery on weekdays.
15-inch vs 13-inch Air — which should I pick?

Pick the 15-inch if the laptop mostly lives on a desk or lap and screen space matters — it's still only 1.51kg. Pick the 13.6” M4 for the same chip in a lighter, cheaper chassis, or the 15” M3 for the same screen at the best value.
