Why sell a current-generation iMac?
All-in-ones depreciate in steps at each refresh, and current machines skim the top of used demand from home offices and creative desks that want a clean display computer without hunting parts. Selling while the M4 is current captures that peak before the next 24-inch chip announcement resets used expectations overnight.
We collect free by courier, so you never wrestle a 24-inch panel to a Post Office. Insurance covers the quoted value in transit. That alone is why many sellers choose cash buyback over trying to list a glass-fronted desktop on a marketplace, where collection risk and no-shows eat the headline figure.
If you are moving to a Studio, mini and monitor, or a laptop-only setup, sell the iMac while buyers still call it the newest 24-inch model. Waiting until the next refresh usually costs more than any convenience of delaying the handover.
Home offices refreshing from Intel all-in-ones are a steady buyer pool for the M4, which keeps liquidity high even in quieter retail months. That demand is why current-generation iMacs usually move faster than older towers of similar cash value.
What moves the price on an iMac M4
Unified memory first, then storage, then cosmetic condition on the aluminium and glass. Because RAM is soldered, list exact GB from About This Mac. Guessing the base memory on the quote form is the fastest way to leave money on the table.
Screen marks and dents matter more on an iMac than on a mini because the display is the product. Be honest in the form; cracked glass still sells with an instant broken-style quote rather than a surprise deduction on arrival.
You do not need the Magic Keyboard or mouse for a quote, but original peripherals can nudge a grade when present and unused. Keep them if you are staying on Mac; include them only if you want a complete handover.
Colour and stand options rarely change the headline much; the chip, memory and screen condition do. If the glass is clean and the ports work, you are already in the strong band for this generation.
Collection, wipe and payment
After you accept the quote we book a courier on a day you choose. Box with generous padding; our desktop packing guide shows how using materials most homes already have. Payment lands within 24 hours of inspection.
Sign out of Find My before collection so Activation Lock never blocks the sale. Every purchased Mac is erased to NIST 800-88 standards after intake, so you do not need a perfect wipe if you are short of time, though a clean erase still speeds intake.
Compare older bands on the iMac hub. An M3 or M1 24-inch still sells; the M4 is simply the current peak for this form factor. Prefer cash to store credit? Specialist buyback usually nets more than manufacturer trade-in on an all-in-one of this age.
If we ever revise a quote on arrival and you decline, the courier returns the iMac free and insured. No return fee, and the 14-day lock means you are never rushed into a bad handoff.

iMac M4 - FAQs
Everything sellers ask us before posting their Mac - answered straight.
How much is an iMac M4 worth in 2026?
Indicatively around £850 in good condition for a 24-inch M4, with higher memory and storage above that. Faulty units typically retain about 40-45%. Your emailed quote is locked for 14 days.
Do you collect iMacs?
Yes. Free, fully-insured courier collection from your door UK-wide. You box it; we carry transit risk up to the quoted value.
Do I need to send the keyboard and mouse?
No. We buy the iMac alone. Keep peripherals if you are staying on Mac, or include them if you prefer a complete handover.
Do you buy broken iMac M4 machines?
Yes. Cracked glass, no-power boards and dead ports still sell. Describe the fault for an instant quote; no photo upload required.
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 an iMac 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.
