One generation old is a strong time to sell
Used buyers pay nearly current-model money for one-generation-old Airs because the day-to-day difference is small for most people. That perception gap is your margin, and it lasts until the next Air launch pushes the M4 further down the curve.
Most M4 Airs we buy come from people switching to a Pro, a desktop, or consolidating kit. If you are upgrading anyway, selling now still captures more than waiting for the following refresh.
One generation behind is still a strong sale because most everyday buyers cannot tell an M4 Air from an M5 across a desk. That perception gap is your margin, and it lasts until the next Air launch pushes the M4 two generations back.
Compare the M5 page if you are choosing which Air to keep. The M4 is the one-behind sweet spot for many students and first-time Mac buyers who want near-current speed without newest pricing.
What an M4 Air is worth by spec
The 15-inch carries roughly a £100 premium over the 13-inch. RAM is the bigger lever this generation - 24GB and 32GB configurations quote well above the base 16GB. Colour makes no difference to us, though Midnight models with visible fingerprint wear can grade slightly lower on condition.
Fill in the quote form with size, RAM and storage and your fixed quote arrives by email within 2 working hours. Damaged M4 Air? Even cracked-screen units retain around half their working value - describe the fault for an instant quote.
Battery health rarely wrecks an M4 quote on a machine this recent. Mention cycle count or health percentage if it is low, and the figure already reflects it. Cracked lids and liquid marks still get instant faulty-grade quotes with no photo upload.
Timing your M4 Air sale around an upgrade
A large share of the M4 Airs we buy come from students and recent graduates trading up. Late summer and early autumn still see strong demand for a clean Air ahead of the academic year.
If you are funding a Pro for a heavier course or a new job, moving the Air on while it is only one generation behind is still the smart play: you capture a strong figure and put that cash straight toward the replacement.
If you are funding a Pro or a desktop, moving the Air on now keeps more of the upgrade budget. Waiting through another launch is the decision that usually costs £100-£150 on this generation.
Broken M4 Airs remain valuable for the same reason: recent displays and boards stay in demand. Describe the fault in the quote form and you will get a fixed figure by email within 2 working hours, locked for 14 days while you pack.
Sign out of Find My before you post. Every Mac we buy is wiped again to NIST 800-88 standards after inspection, so Activation Lock is the one prep step that truly protects a smooth payment.
Good to know
MacBook Air M4 - FAQs
Everything sellers ask us before posting their Mac - answered straight.
How much is a MacBook Air M4 worth in 2026?
Indicatively, around £720 for a 13-inch in good condition and £820+ for the 15-inch, with RAM upgrades adding more. Faulty units typically fetch 45-50% of working value. Your emailed quote is the exact price we pay, locked for 14 days.
Is the M4 still worth selling now the M5 Air is out?
Yes. The M4 is one generation behind, not obsolete, and stays in strong demand. Its steepest drop already happened when the M5 landed; from here it eases down more gently. If it is idle or replaced, selling now still beats waiting.
Does the 15-inch M4 Air sell for more?
Yes, typically about £100 more than the equivalent 13-inch. Both sizes are in strong demand - the Air is the UK's most-bought Mac, so used ones sell quickly and prices stay liquid across the range.
Do you buy damaged M4 MacBook Airs?
Yes - cracked screens, dents, liquid damage, dead units. A faulty M4 Air still fetches around £330 because parts carry premium value. Describe the fault in the quote form and the quote arrives instantly, no photos needed.
About the buyer
What is SellMacBooks?
SellMacBooks is a UK buy-back service for Apple computers only. We have no shops and no drop-in counter: every sale runs by post, anywhere in the country. You describe your Mac, we email a fixed quote within 2 working hours, you post it free on a fully insured label, and payment leaves by bank transfer within 24 hours of the machine passing inspection.
We buy Apple Silicon Macs only - M1-generation and newer (2020 onward), working or broken. We do not buy Intel Macs. Macs are the only thing we handle, so the person pricing yours knows what the model is worth this month rather than reading it off a generic gadget table. See how it works or read about us.
The inspection
Everything we check before quoting a MacBook Air M4
Your quote is built from what you tell us, and the bench check on arrival exists to confirm that description rather than renegotiate it. Here is exactly what we look at:
- Power-on and a clean boot to the desktop
- Screen: cracks, dead pixels, backlight and marks
- Chassis and cosmetics: dents, deep scratches, worn palm rests
- Battery health percentage and cycle count
- Keyboard, trackpad, speakers and every port
- Storage size, memory and chip against the spec you quoted
- Find My / Activation Lock signed out (we cannot buy a locked Mac)
- Accessories included, such as the original charger
The quoted price is fixed and locked for 14 days. If the machine differs from your description, you get photos and a plain explanation with a revised offer - accept it, or decline and we return the Mac free and insured. Full detail on the three grades is on our grading page.
Versus the alternatives
How we compare
Selling a Mac in the UK usually comes down to a big trade-in site, a marketplace listing, or a specialist buyer like us. The differences that cost sellers money are these:
- Big trade-in sites can keep you waiting days after delivery. We pay within 24 hours of your Mac passing inspection.
- eBay takes roughly 14% in fees, plus postage, plus return and scam risk. Our quote is the amount that lands in your bank.
- Some buyers put the courier damage risk on you in their small print. Our label is insured at our expense, both ways.
- Return fees for declining a revised offer are common in this market. Ours are always free, both ways, whatever inspection finds.
- Most quotes quietly expire or float with the market. Yours is locked for 14 days.
