Why high-memory M4 Max laptops resell so well
The M4 Max is the only truly portable Mac that can hold large models in memory, so it's bought by people who need a workstation they can carry - AI engineers, VFX artists, developers. Because unified memory is fixed at purchase, the 64GB and 128GB builds are scarce on the used market and priced at a premium: the step from 36GB to 128GB can add £700 or more to your quote.
That demand is durable. Even a generation on, buyers who want serious on-device compute without paying new-Max prices keep the M4 Max liquid - so it depreciates far slower than a base MacBook Pro.
What your M4 Max is worth by build
Memory first, then screen size, then storage. A 16-inch 128GB machine can be worth £1,000 more than a 14-inch 36GB M4 Max. High-capacity SSDs (2TB, 4TB, 8TB) add meaningfully too, because AI and video work fills them fast. Cosmetic condition matters but battery cycles barely register on a machine this recent.
Put the exact memory, size and storage into the quote form and your fixed quote arrives by email within 2 working hours. Cracked screen or a fault? We quote those instantly - a faulty M4 Max still holds serious value because its board and memory are in demand.
Selling before you move to the M5 Max
The M5 Max has landed, so the M4 Max is one generation behind - its steepest drop is already past, and what's left is a gentle slope held up by the high-memory demand above. If you're upgrading to an M5 Max anyway, selling now still captures more than waiting for the M6 will.
Post it free with our insured label; for a machine worth this much, the transit insurance covering its full quoted value matters - if anything happened on the way to us, you'd still be paid in full.
Good to know
MacBook Pro M4 Max - FAQs
Everything sellers ask us before posting their Mac - answered straight.
How much is a MacBook Pro M4 Max worth in 2026?
Indicatively: a 16-inch M4 Max from around £1,600, with 64GB builds higher and a 128GB machine up to £2,600 - the memory buyers pay most for. Faulty units retain 40-50%. Your emailed quote is the exact price we pay, locked for 14 days.
Does the 128GB M4 Max really sell for that much more?
Yes. Unified memory is fixed at purchase, and 128GB is what lets a laptop run large AI models on the move - so it's scarce and sought-after. The jump from 36GB to 128GB can add £700 or more to your quote versus the base configuration.
Is it worth selling my M4 Max now the M5 Max is out?
If you're upgrading anyway, yes. The M4 Max's biggest price step already happened when the M5 Max launched; from here it eases down slowly, propped up by strong demand for high-memory portable machines. Selling before the next generation still beats waiting.
Do you buy M4 Max laptops with faults?
Yes, and they hold value well - a faulty 16-inch M4 Max is still a four-figure machine because its board and memory are exactly what buyers want. Describe the fault in the quote form for an instant quote; no photos, no renegotiation if the description matches.
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 Pro M4 Max
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.
