M6 Mac Mini Buying Guide: Which One Is For You?

If you need a new Mac mini, the choice can be rather overwhelming. Exciting. But quickly overwhelming.

In August 2026, Apple introduced a new M6 Mac mini and an M5 Pro Mac mini (and an even more super-powered Mac Studio, but that’s for another day). The latest Mac minis are more expensive than the models they replace (in some instances, considerably so), and to make things even more agonising, the M4 Mac mini is now flooding the Apple refurb store and second-hand market at very tempting prices.

Oh, and let’s not forget the pre-redesign M2 Mac mini. That remains very interesting in a world where everything is really expensive, doesn’t it?

The good news is that I’ve been reviewing and assessing Mac minis for years, and I’m confident I know how to help you buy the right one.

Let’s get straight into it.

The M6 Mac Mini

If you want the latest entry-level Mac mini, it now comes with a monstrously powerful M6 chip, and it starts at £899/$899 (education discount: £799/$799).

For that, you get a CPU that’s 40% faster than the M4 version, four times faster AI, and up to twice as fast graphics and storage. The design remains the same as before, as does the port selection (three Thunderbolt 4, two front USB-C, and one HDMI), although Ethernet has been upgraded to 2.5Gb as standard.

The M6 specs are impressive – it’s the first Mac chip built on a 2nm process, and you get a 12-core CPU, 12-core GPU, 16-core Neural Engine, 16GB of unified memory as standard, and the ability to configure the latter up to 32GB. Storage ranges from 256GB to 2TB. The most you can spend on an M6 Mac mini is £2,399/$2,399.

As one should expect in 2026, the key upgrade relates to AI performance and the latest Neural Engine inside the Mac mini. It is, arguably, the first base Mac mini that can be considered a relatively serious local AI machine.

That means if you’re interested in cutting the cord from the big AI firms and setting up your own LLM that doesn’t need an internet connection to help you with your report writing, the M6 Mac mini could be the machine for you.

Equally, if you’re upgrading from an older Mac mini and want to know you’re moving across to the latest and greatest, the M6 Mac mini will remove any form of buyer’s remorse you may suffer if you choose something else.

But what if the M6 Mac mini isn’t powerful enough for you?

The M5 Pro Mac Mini

At £1,699/$1,699 (education discount: £1,599/$1,599), the M5 Pro Mac mini, despite technically being one generation behind the M6 base model, heads into serious desktop computer territory.

It can be configured with up to an 18-core CPU, 20-core GPU, 8TB of storage, and 64GB of unified memory (it starts with 24GB). The most you can spend on an M5 Pro Mac mini is a trouser-erupting £6,799/$6,799.

What do you get over the M6 version? Well, beyond the higher-spec options, the M5 Pro Mac mini also has more memory bandwidth, enhanced shader cores and third-generation ray tracing support, and Thunderbolt 5 ports. Versus the outgoing M4 Pro Mac mini, the M5 Pro version promises:

• up to 4x faster LLM prompt processing in LM Studio;
• up to 1.4x faster rendering with ray tracing in Blender; and
• up to 1.5x faster image processing in Affinity.

That’s significant, and if any of the above means anything to you and is important to you, the M5 Pro Mac mini is the one to get. The higher unified memory and storage ceiling, combined with the presence of Thunderbolt 5 angles the more expensive Mac mini toward serious creative and business use.

It will, of course, be even better than the M6 version at AI stuff, too – particularly with the ability to add a significant amount of memory.

However, as I always say, if you don’t know whether you need all of this stuff, you probably don’t. The M6 Mac mini will do you just fine.

But I know you’re tempted by something else, so let’s address the mini elephant in the room.

The M4 and M4 Pro Mac Mini

While the M4 and M4 Pro Mac mini might have left Apple’s official store shelves, it is starting to appear on the Cupertino company’s refurb store. At the time of writing, the UK version of that store lists the entry-level M4 Mac mini from £679, with meatier configurations at £849 (was £999) and £1,019 (was £1,199).

This is why that pesky elephant won’t leave the room. The M4 and M4 Pro Mac mini remain utterly superb desktop Macs in 2026, regardless of the numbers attached to their replacements.

What you don’t know won’t hurt you, as they say.

Even if the performance difference does bother you a little, you’ll probably be buoyed by the fact that the previous generation Mac mini possesses the same chassis, design, and port selection (on both versions – the M4 Pro also has Thunderbolt 5). And, if you buy yours via the Apple refurb store, you’ll get full warranty, a new outer shell, and other new bits where applicable. It’s basically a brand-new Mac in brown packaging.

Hit the second-hand market, and you’ll probably save even more if you don’t mind buying someone else’s beloved Mac mini, which might have a sign or two of use.

If you’re really interested in local AI performance, the M6 Mac mini is a sensible investment. Equally, if this is to be a machine that feeds your business bank account and you work in serious creative, coding, or AI fields, the M5 Pro is the one to get.

If you don’t fall into either of those camps, the M4 generation Mac mini is looking like more of a bargain by the day.

The M2 Mac Mini

If your budget is on the low side and you have zero interest in the latest and greatest, there’s another option.

We still have an M2 Pro Mac mini in my studio, and it doesn’t feel like a three-year-old computer. Sure, it doesn’t have the CPU, GPU, or AI performance of the M6 Mac mini, let alone the M5 Pro Mac mini, but that doesn’t matter. It does the job for us.

It also has two USB-A ports, which the latest Mac minis don’t have. That’s an easy benefit to overlook.

It could do the job for you, too, particularly if you’re looking for a Mac mini to act as a home media server, a Plex box, a simple Claude box, or a machine for your kids to use.

Apple doesn’t stock the M2 generation Mac mini on the refurb store, but the second-hand market is awash with them, and as M6 Mac mini deliveries start to make their presence felt, it’ll be even more awash.

Just one word of warning. The M2 Mac mini shipped with 8GB of unified memory as standard. I’d remove that from your search filter and look for 16GB upwards.

Wrap Up

The Mac mini has always been a wonderful computer, but there has never been a better time to be in the market for one.

Everything is expensive in 2026, therefore, if you can save several hundred pounds or dollars on your next Mac desktop, you’re spoilt for choice.
