01
Which Mac mini are you selling?
The chip tier is the first question, and on this machine it is the one that moves the number most. The current generation runs the M4 and the M4 Pro, which are priced separately because the Pro is a materially different machine rather than a faster version of the same one. Before that came the M2 and M2 Pro years, and the M1 before them.
What a buyer is paying for is the combination, not the badge. An M4 with the base memory and the entry SSD, and an M4 Pro loaded with memory and a large drive, are different products commercially even though both are "a Mac mini M4 generation".
If you do not know your configuration, you do not need to work it out. Click the Apple menu, then About This Mac, and send us a screenshot of what appears. That single screen carries the chip, the memory and the macOS version, and it settles the question faster than any description.
02
Why the configuration matters more than the model name
Chip tier first, as above. Then unified memory, which is the item most often underestimated. Memory is soldered on Apple silicon and cannot be added later, so a mini ordered with more of it stays more valuable for its whole life. The same applies to the SSD: capacity is fixed at purchase, and the larger configurations are worth noticeably more than the entry drive.
Ports come next, and they matter more on a desktop than on a laptop, because the machine lives on them. Thunderbolt ports, the USB ports, the HDMI output and ethernet are all tested, and a dead port is a heavier deduction here than it would be on a MacBook.
Then the physical state, which on a mini is usually mild: scuffs on the base, marks around the port cluster, occasionally a dented corner. Normal desk wear is priced in rather than argued over.
Repair history closes it. A replaced power supply, a board worked on outside Apple, or a third-party drive in one of the Intel-era machines all change what the next owner is buying. Say so upfront and the quoted number holds.
03
How to find your Mac mini specification
Apple menu, About This Mac. Screenshot it and send the screenshot. It gives us the chip, the memory and the macOS version in one shot, and it removes every round of guessing.
For the storage figure, open System Settings, then General, then Storage, and read the total capacity rather than the free space. Those are different numbers and only one of them is useful to us.
If the machine will not boot, that is not a problem and it does not end the quote. Tell us what it does when you press the power button, whether it chimes, whether anything appears on a connected display, and send a photo of the back of the unit showing the port layout. The port layout alone narrows the generation considerably.
One thing you should not do, here or anywhere else: post the serial number publicly. We do not need it for a quote, and it is checked at inspection with you present.
04
Selling a Mac mini with accessories
The one thing to bring is the power lead. A mini we cannot power on is a mini we cannot test, and an untested machine cannot carry a firm price, so this matters more than any other accessory.
An Apple Magic Keyboard, Magic Mouse or Magic Trackpad that came with the machine or was bought alongside it can be included, and each is valued as its own item rather than folded into the price of the mini. Tell us the model and whether the batteries or internal cells still hold a charge.
A display can be included if it is an Apple one. Third-party monitors, hubs, docks and generic peripherals sit outside what we resell, so we would rather say so now than have you carry them across town for nothing.
The original box is welcome and adds a little, mostly because it makes the machine easier to move on intact. It is not required.
05
Selling several Mac minis from an office?
A rack of minis coming out of a studio, a lab or a finance floor is a different job from selling one, and it is handled differently. Send a list with the quantity, the chip tier, the memory and storage of each configuration, the rough condition, and one detail people often forget: whether the machines are still enrolled in company device management.
A batch is valued unit by unit and then settled as one figure and one invoice, so a dead machine in the corner of the pallet does not drag down the working ones. Collection is free and we come to your office rather than asking anyone to move hardware.
Every unit is wiped and a certificate issued per device. If the estate runs to more than minis, and it usually does, the corporate IT fleet page covers how a mixed collection is quoted and settled.
06
Prepare your Mac mini before you sell it
Back up first, to Time Machine or to a drive you keep, and confirm it finished. Everything after this erases the machine.
Then sign out of iCloud and turn off Find My Mac. On Apple silicon, run System Settings, General, Transfer or Reset, then Erase All Content and Settings, which clears Activation Lock as part of the process. An Activation Lock nobody can clear is the one thing that stops a sale outright, and it cannot be lifted at our counter or yours.
If the machine came from an employer, check whether it is still enrolled in mobile device management before you erase it. A managed Mac re-enrols itself on setup and has to be released by whoever issued it, which is a conversation with your IT department rather than something we can do at the desk.
Then bring it with its power lead. Nothing else is required.
