Sell Your Mac mini M4 Pro

M4 or M4 Pro: how to tell which Mac mini you have

Both chips shipped in the same 2024 redesign, the small square case with two ports on the front and the power button underneath, so the outside will not tell you. About This Mac names the chip in its first line. If the mini will not start, look at the three USB-C ports on the back: on the M4 Pro they are Thunderbolt 5, and on the base M4 they are Thunderbolt 4. The HDMI port, the Ethernet port and the two front USB-C ports are the same on both.

The M4 Pro itself came in two versions. The standard chip has a 12-core CPU and a 16-core GPU; the upgrade has 14 CPU cores and 20 GPU cores. Memory was 24GB as standard, with 48GB and 64GB as options, and 64GB was never offered on the base M4 at all. Storage ran from 512GB to 8TB. Copy the core counts, memory and storage from About This Mac into the quote form, because those figures decide the price, not the chassis.

One more option is invisible from outside: 10Gb Ethernet. It was a paid upgrade over the standard Gigabit port, and the buyers who want an M4 Pro mini as a small server or a shared render node care about it. Check the Ethernet line under System Report, or your original order, and mention it if you have it.

What decides a Mac mini M4 Pro quote

Memory first, storage second, then the chip version. Memory cannot be added after purchase, so a 48GB or 64GB machine sits well above the 24GB base at resale; developers running containers, editors and anyone experimenting with local models buy for headroom. A 1TB or 2TB drive adds a clear step over 512GB, and the 4TB and 8TB drives more still.

Condition barely moves the number on a mini. There is no display and no battery, so scuffs on the aluminium cost next to nothing. Faults do count, but they do not sink the machine: a dead port, a fan that has stopped or a board that will not power on still sells, at around £250 for a faulty M4 Pro, because the memory and logic board keep their parts value. Describe the fault in the form and the figure is instant, with no photos.

This page is for the Pro chip. If yours is the base M4 mini, its page carries the £380 figure and the 16GB, 24GB and 32GB memory tiers. If you own the newer M5 Pro mini, that page prices the current pro-tier machine.

Now one behind the M5 Pro mini: sell or keep?

The M5 Pro mini went on sale on 22 September 2026, and that launch was the step down the M4 Pro was always going to take. What follows is a gentler slope until the next pro-tier refresh, when it becomes two generations old and drops again. If the machine is idle, or an M5 Pro or a Studio has already replaced it, the months before that refresh are the better time to sell.

The case for keeping it is real too. An M4 Pro with 48GB or 64GB still handles serious compile, edit and inference work, and Thunderbolt 5 keeps it current for fast external storage. Nobody should sell a daily machine to chase a curve. Selling makes sense when the mini has become the spare, because a spare loses a little more at every Apple event.

Upgrading anyway? Quote the M4 Pro first and hold the price. The 14-day lock gives you time for the new machine to arrive and for Migration Assistant to move everything across before you box the old one.

Posting a Mac mini M4 Pro

The mini is the easiest Mac to sell by post: the power supply is built in, so there is no brick to find, and the whole machine fits in a shoebox with padding. Print the free insured label we email, hand the parcel in at any Post Office, and the transit risk is ours up to the quoted value. You do not need to send the power cable, a keyboard, a mouse or a display.

Sign out of your Apple Account and turn off Find My before you pack it, so the mini is not Activation Locked. Leave the erase to us: every Mac we buy is wiped to NIST 800-88 standards after inspection. Payment follows within 24 hours of the mini passing, and if a revised quote is ever declined we return it free and insured, with no fee.
