Best Thunderbolt 4 Dock for Mac in 2025: OWC 11-Port vs OWC Go Dock (UK Guide)
If you've been shopping for a Thunderbolt 4 dock for your Mac, you've probably already noticed that OWC makes more than one. There's the OWC 11-Port Thunderbolt 4 Dock, there's the OWC Thunderbolt Go Dock, and depending on what you need, the right answer isn't always obvious.
This guide cuts through the spec sheets. We'll tell you exactly what each dock does, who it's for, and which one you should buy — based on how you actually use your Mac.
Why Thunderbolt 4 matters in 2025
Before we get into the comparison, it's worth a quick word on why Thunderbolt 4 is still the right choice for most Mac users in 2025 — even as Thunderbolt 5 starts to appear.
Thunderbolt 4 delivers 40Gbps of bandwidth. For the overwhelming majority of workflows — including 4K video editing, photography, audio production, software development, and general creative work — 40Gbps is more than enough. Thunderbolt 5 docks exist, but they're more expensive, and unless you're working with 8K RAW footage or multiple high-bandwidth drives simultaneously, you won't feel the difference.
Every modern Mac — from the MacBook Air M2 onwards, through the MacBook Pro M3/M4, Mac mini M4, iMac M4, and Mac Studio — works perfectly with Thunderbolt 4 docks. One cable from your Mac to the dock, and everything else plugs into the dock.
OWC 11-Port Thunderbolt 4 Dock — The Desktop Workhorse
The OWC 11-Port Thunderbolt 4 Dock is the one that lives on your desk and doesn't move. It's compact — only 19.8cm wide and less than 3cm tall — but it's packing serious connectivity.
What you get:
- 1 x Thunderbolt 4 upstream port (to your Mac)
- 3 x Thunderbolt 4 downstream ports (for drives, displays, accessories)
- 3 x USB-A 3.2 Gen 2 (10Gbps)
- 1 x USB-A 2.0
- 1 x Gigabit Ethernet
- 1 x SD card reader
- 1 x 3.5mm audio combo jack
- Up to 96W power delivery to your laptop
Display support is excellent: you can run two 4K displays at 60Hz, a single 5K or 6K display, or push all the way to 8K at 60Hz. For most professionals — including photographers, video editors, and developers — dual 4K covers everything.
The dock comes with a 0.8m Thunderbolt 4 cable included, a 2-year OWC warranty, and uses an external power adapter (135W total). The aluminium chassis runs cool and quiet, and there's a subtle adjustable LED if you want to dial in your desk aesthetic.
Who it's for: Anyone building a permanent desk setup. You dock once in the morning, charge your MacBook at up to 96W, run your monitors, connect your drives and peripherals, and pick up the laptop when you leave. It's the one-cable solution for a serious workstation.
OWC Thunderbolt Go Dock — The One That Goes With You
The OWC Thunderbolt Go Dock is something genuinely different: it's the world's first full-featured Thunderbolt dock with a built-in power supply. No external power brick. You plug a standard figure-8 power cable directly into the dock itself — the same type of cable used by countless devices you already own.
That matters more than it sounds. If you travel with a dock, a traditional external power adapter adds weight, takes up bag space, and is one more thing to forget or lose. The Go Dock solves that by folding the power supply inside the aluminium chassis.
What you get:
- 1 x Thunderbolt 4 upstream port (to your Mac)
- 2 x Thunderbolt 4 downstream ports
- 1 x USB-C 3.2 Gen 2 (10Gbps)
- 2 x USB-A 3.2 Gen 2 (10Gbps)
- 1 x USB-A 2.0
- 1 x HDMI
- 1 x 2.5 Gigabit Ethernet (faster than standard 1GbE)
- 1 x SD card reader (UHS-II)
- 1 x 3.5mm audio output
- Up to 90W power delivery to your laptop
The Go Dock has one fewer Thunderbolt downstream port than the 11-Port, but compensates with 2.5GbE networking and the addition of an HDMI port — useful when you're connecting to hotel room screens, conference room displays, or client setups where you can't assume a Thunderbolt display is waiting for you.
Display support matches the 11-Port: two 4K displays at 60Hz, or up to 8K at 60Hz.
Who it's for: Video professionals who work across locations. Hybrid workers splitting time between a home office, studio, and client sites. Anyone who travels regularly with their MacBook and wants full dock functionality without a bag full of adapters and bricks.
Head-to-Head Comparison

| Thunderbolt 4 downstream ports | 3 | 2 |
| USB-A ports | 4 (3x 10Gbps + 1x 2.0) | 3 (2x 10Gbps + 1x 2.0) |

| Weight | 400g | 949g |
| Best for | Fixed desk setup | Mobile / multi-location |
Worth noting: the Go Dock is actually £11 cheaper than the 11-Port, despite including an HDMI port, faster ethernet, faster SD reader, and no external power brick. If you're on the fence, the value case for the Go Dock is strong.
Which one should you actually buy?
Buy the OWC 11-Port Thunderbolt 4 Dock if:
- Your Mac lives on one desk, most of the time
- You need three Thunderbolt downstream ports to connect drives, enclosures, and a display
- You want 96W charging to keep a 16-inch MacBook Pro fully topped up
- You don't care about the power brick because it stays plugged in anyway
Buy the OWC Thunderbolt Go Dock if:
- You work across multiple locations and take your Mac with you
- You want cleaner cable management with no external power brick
- You need 2.5GbE for faster network performance
- The HDMI port is important for your setup
- You want the faster UHS-II SD card reader for ingesting footage on the road
A note on M1 MacBook Air and base M1/M2/M3 Mac mini: These models only support a single external display via Thunderbolt. So whether you buy the 11-Port or the Go Dock, you'll only get one monitor working over Thunderbolt on those machines. If multi-monitor is essential, consider the MacBook Pro M-series or Mac mini M4 which have full multi-display support.
A word on Thunderbolt 4 vs USB-C
Both docks work with USB-C Macs and devices too — not just Thunderbolt. If you plug in a MacBook with a USB-C port rather than Thunderbolt, the dock functions as a USB hub. You won't get Thunderbolt speeds, but you still get connectivity. And if you're using a Thunderbolt 3 Mac (anything from 2016 onwards), both docks work fully — backward and forward compatibility is built in.
