Apple Mac mini (2024), Apple M4, 16GB, 256GB review

This is the base Mac mini with the Apple M4, 16GB of unified memory and a 256GB SSD. It targets people who want a compact desktop that sips power. The headline figure is an idle draw of 4W, measured at the wall for this configuration. Maximum draw is 65W. Apple also states the unit is ENERGY STAR certified.

The trade-off is flexibility. Memory and storage are fixed at purchase, and the network connection on the base model is Gigabit. Those points shape who should buy it.

The M4 has a 10-core CPU, split into four performance cores and six efficiency cores. It also has a 10-core GPU and a 16-core Neural Engine. Owners repeatedly point to performance for the money as a strength.

Memory is 16GB of unified memory. It is soldered, and there is no DIMM or SO-DIMM slot. The maximum is 32GB, and Apple lists that as a choice you make when you configure the machine at purchase. With a 16GB base and a 32GB ceiling, anyone planning heavier multitasking or several concurrent workloads should decide on memory before ordering, because it cannot be changed later.

The 4W idle figure is the strongest part of this machine's case for a homelab or an always-on desk box. At that level, leaving it running around the clock costs little in electricity. Owners name low idle power as a recurring positive.

The 65W maximum gives a ceiling for planning, for example when sizing a power strip or a UPS. Apple's ENERGY STAR certification backs up the efficiency story.

The base model has a 256GB SSD. Owners say that fills quickly, and they also flag that the storage cannot be upgraded. ServeTheHome describes the SSD as not user-upgradable. Together with soldered memory, that means the internal specification you buy is the one you keep.

The small base drive is the obvious limit here. If you expect to hold large datasets, VM images or media locally, the 256GB capacity is likely to feel tight. Because the SSD is not user-upgradable, that capacity is what the machine has for its whole life.

The base model has Gigabit Ethernet (10/100/1000BASE-T, RJ-45). Wi-Fi 6E (802.11ax) and Bluetooth 5.3 are built in. Apple offers 10Gb Ethernet as a configure-to-order option, but it is not part of the base configuration.

For a homelab, Gigabit is the main networking limit. It is fine for light services and general use. Anyone moving large files across the network, or building around faster links, should look at the 10Gb option at the time of purchase rather than the base unit.

The back has three Thunderbolt 4 (USB-C) ports supporting USB 4 at up to 40Gb/s and DisplayPort, plus an HDMI port and the Ethernet jack. The front has two USB-C ports (USB 3, up to 10Gb/s) and a 3.5mm headphone jack.

That is a good spread of high-speed ports and display outputs. The catch is that the Mac mini has no USB-A ports. Owners call this out as a recurring annoyance. If you have older USB-A peripherals, keys or adapters, budget for a hub or adapters.

Feedback is consistent. People like the low idle power and the performance for the money. They dislike the small base storage, the fixed internal storage and the lack of USB-A. None of these are surprises given the specification, and all of them come down to deciding on configuration before you buy.

The M4 Mac mini makes sense if its fixed hardware matches your needs from day one. A 4W idle draw, a 10-core chip and three Thunderbolt 4 ports are strong points. Soldered memory, non-upgradable storage and Gigabit-only Ethernet on the base model are the constraints to weigh.
