Your Mac mini needs these 8 upgrades to become a serious AI agent

Yes, you could rely on the Mac mini’s built-in Wi-Fi, but a wired Ethernet network connection offers consistency, and when you’re moving a lot of data around, a stable connection is just as important as a fast one. The Mac mini has a gigabit Ethernet port, so you might as well take advantage of it with a Cat 7 cable for the best possible speeds at all times. You can learn more about why all Ethernet cables aren’t the same from our friends at Tech Advisor.

The last thing you want to happen is to have your Mac abruptly shut down in a power outage while your AI agent is doing its thing. That’s why you need an uninterruptible power supply (UPS). This CyberPower unit has 6 battery-backed and surge-protected outlets, which should be enough for your Mac mini, display, router, and other items, such as external storage devices. It also has six surge-protected (but not battery-backed) outlets for non-essential things. This particular device offers 83 minutes of runtime (based on 100 watts of usage), but CyberPower also offers smaller UPSs if they are a better fit for your budget.

With all the work your Mac mini is going to do, you need to make sure it can stay cool. Standing it vertically allows more air to flow through the Mac mini’s bottom vents, and a stand like this well-liked one from Snanshi can help keep the Mac mini in place—and running cool.

The Mac mini is available with up to 8TB of internal storage, but it’ll cost nearly $5,500. Instead, consider a fast external SSD for storing your AI models and other data. OWC’s 1M2 has a USB4 port rated at 80Gbps— plenty fast for AI work—and plugs right into the Mac mini’s Thunderbolt port. It’s available as a case only so you can provide your own PCIe Gen 3.0/4.0/5.0 NVMe M.2 SSD, or you can get it with an SSD module in capacities up to 8TB. See our other best picks for external SSDs.

Since your Mac mini AI agent is doing very important work, you should back up its data on a regular basis. You can use a slower hard drive for Time Machine backups, which is much cheaper than the SSD above. Don’t worry about the speed; backups can run overnight or whenever your agent has some down time. See our best picks for external hard drives.

If you plan to do any work with voice AI agents, then you should have a quality microphone for dictation and other voice instructions. We use the MV7+ for the Macworld Podcast and love it. It connects via USB-C, and this model in particular includes a tripod. You can get it with or without a tripod in either black or white.

Even if you’re not working on voice AI agents, you may want an external speaker for your Mac mini. There’s a wide variety to choose from, from cheap desktop speakers to devices designed for serious audiophiles. We picked the Bluetooth Beats Pill because it’s small, produces good sound, and can double as a portable speaker.

If you’re using a display without a built-in webcam, you’ll need to get one, and we like the Brio. It offers auto-light correction and very sharp and detailed picture quality at 4K/30 frames per second. Read our best picks for Mac webcams.
