Apple announced a series of new Macs running Apple Silicon, but they have limited ports. AppleInsider has gathered the best Thunderbolt 3 docks to pair with your new Mac.
The new MacBook Air, 13-inch MacBook Pro, and Mac mini have only two Thunderbolt 3 ports for charging and connecting peripherals. If you need to connect more to your devices, you'll need a dedicated hub.
The Mac mini has an additional auxiliary jack, Ethernet port, HDMI port, and two USB-A ports, but for some desktop users this still won't be enough.
You can find dozens of docks online, but very few will actually meet an individuals requirements. So it is important to understand why you'd want a dock and what to look for when shopping before even making a purchase.
Read below to find out more about Thunderbolt 3 docks, or skip ahead to the list of docks recommended by AppleInsider.
What does a Thunderbolt 3 dock do?
Simply put, a Thunderbolt 3 dock plugs into a Thunderbolt 3 port via USB-C, and in exchange provides a multitude of other connections. Think of it as a USB hub, but instead of simply providing more of the same port, the dock usually includes a selection of commonly-used connections, alongside another Thunderbolt 3-capable port.
This selection typically includes USB Type-A ports, USB-C, video outputs like DisplayPort or HDMI, Gigabit Ethernet, and memory card slots. Some models also offer legacy connections, including eSATA, VGA, and occasionally FireWire, which may have limited utility for most users, but could be essential for people with older hardware that simply doesn't support newer variants.
Some Thunderbolt 3 docks offer Power Delivery too, which means your portable Macs will be able to receive power via the dock, as well as power all peripherals without draining the battery. The single cable will attach you to all of your needs without fighting cables or finding outlets.
Even though many docks offer multiple video connections like HDMI and Displayport, your M1 powered Mac can only connect to one external display via Thunderbolt.
Why do I need one?
The simplest answer is to have more connection options. Each of the new M1 powered Macs have only two Thunderbolt 3 ports, which can be rather limiting. Even with the Mac mini's additional ports, users may need even more ports or legacy connections in order to get the job done.
There's also something to be said about using it as a central docking point for a home setup. If the display, network, external drives, speakers, and peripherals are all connected up to the dock, the user could simply connect all of them at once to the MacBook Pro using a single Thunderbolt 3 cable. One cable attachment and you're fully connected to everything, even if you're using an 18-port hub.
This fast connection is also accompanied by a quick disconnection routine, as users could simply unplug the dock and take their MacBook Pro with them, while still leaving a fully-usable desktop setup at home or in the office, ready and waiting for their return.
What should I look for?
The first consideration is what ports are required. This will largely be determined by the user's present hardware needs, though they will also have to take into account any future items they may need ports for. It's typically better to go over the top with ports than to stick with just what you need.
Don't be afraid to "future proof" either. Just because you don't need a certain port now doesn't mean that you won't need it later. Consider all possibilities, especially with relatively new specs.
In the same vein, remember to take into account the data needs of the devices that you are plugging into the dock. Thunderbolt 3 offers 40Gbps of bandwidth, which is a considerable amount to use, but while it is more than enough for a Gigabit Ethernet connection, a display, and a smattering of slower connections, it can still be overwhelmed in some situations.
Remember to take advantage of the second Thunderbolt 3 port too. Connect a bunch of peripherals to the dock then leave that spare Thunderbolt 3 port for a direct connection to your external storage for optimum speeds.
Take note of what wattage your device needs to receive a charge before buying a dock with Power Delivery. In effect, you need a dock with at least 30W power delivery to fully power a MacBook Air, a 60W version for a 13-inch MacBook Pro, 87W for the 15-inch MacBook Pro, and 96W for the 16-inch MacBook Pro. The Mac mini is constantly connected to power so you don't need Power Delivery if purchasing for that machine.
And finally, pay attention to the specifications of the dock's ports. If you need DisplayPort or want to connect HDMI2.0 via your dock, look for those specs. Some USB-A ports will be USB 2.0 and not the faster USB 3.2, so know your needs there. If connecting a microphone or keyboard, USB 2.0 is fine, but anything else may want a better spec.

Again, docks with multiple display-out options will still only support one of those connections at a time when using an M1 powered Mac. Docks with three or more display-out connections may not be worth the extra cash unless they include crucial ports for your work. Dock manufacturers will likely consider this limitation in future models of their Mac-specific docks.
